Chapter 2 Installing the Server

Initial Server Setup

This section includes the following topics:

•

Connecting and Powering On the Server (Standalone Mode), page 2-8

NIC Modes and NIC Redundancy Settings, page 2-11

Connecting and Powering On the Server (Standalone Mode)

This section describes how to power on the server, assign an IP address, and connect to server

management when using the server in standalone mode. To use the server in a Cisco UCS integration,

specific cabling and settings are required. See Installation for Cisco UCS Integration, page D-1.

Note

The server is shipped with a default NIC mode called Shared LOM EXT, default NIC redundancy is

active-active, and DHCP is enabled. Shared LOM EXT mode enables the 1-Gb Ethernet ports and the

ports on any installed Cisco virtual interface card (VIC) to access the Cisco Integrated Management

Interface (CIMC). If you want to use the 10/100 dedicated management ports to access the CIMC, you

can connect to the server and change the NIC mode as described in Step 4 of the following procedure.

In that step, you can also change the NIC redundancy and set static IP settings.

To perform initial setup of the server, follow these steps:

Step 1

Attach a supplied power cord to each power supply in your server, and then attach the power cord to a

grounded AC power outlet. See the Power Specifications, page A-2 for power specifications.

Wait for approximately two minutes to let the server boot in standby power during the first bootup.

You can verify the power status by looking at the Power Status LED (see Figure 1-1 on page 1-1):

•

Off—There is no AC power present in the server.

Amber—The server is in standby power mode. Power is supplied only to the CIMC and some

motherboard functions.

•

Green—The server is in main power mode. Power is supplied to all server components.

Note

During bootup, the server beeps once for each USB device that is attached to the server. Even if

there are no external USB devices attached, there is a short beep for each virtual USB device

such as a virtual floppy drive, CD/DVD drive, keyboard, or mouse. A beep is also emitted if a

USB device is hot-plugged or hot-unplugged during a BIOS power-on self test (POST), or while

you are accessing the BIOS Setup utility or the EFI shell.

Step 2

Connect a USB keyboard and VGA monitor by connecting the supplied KVM cable to the KVM

connector on the front panel (see Figure 1-1 on page 1-1).

Note

Alternatively, you can use the VGA and USB ports on the rear panel. However, you cannot use

the front panel VGA and the rear panel VGA at the same time. If you are connected to one VGA

connector and you then connect a video device to the other connector, the first VGA connector

is disabled.

Step 3

Connect Ethernet cables to the server ports or card ports that you want to use.

Chapter 2 Installing the Server

Initial Server Setup

Step 4

Set NIC mode and NIC redundancy, and choose whether to enable DHCP or set static network settings:

a. Press the Power button to boot the server. Watch for the prompt to press F8.

b. During bootup, press F8 when prompted to open the BIOS CIMC Configuration Utility.

c. Set the NIC mode to your choice for which ports to use to access the CIMC for server management

(see Figure 1-2 on page 1-2 for identification of the ports):

•

Shared LOM EXT (default)—This is shared LOM extended mode. This is the factory-default

setting, along with Active-active NIC redundancy and DHCP-enabled. With this mode, the shared

LOM and Cisco Card interfaces are both enabled.

In this mode, DHCP replies are returned to both the shared LOM ports and the Cisco card ports. If

the system determines that the Cisco card connection is not getting its IP address from a Cisco UCS

Manager system because the server is in standalone mode, further DHCP requests from the Cisco

card are disabled. Use the Cisco Card NIC mode if you want to connect to the CIMC through a Cisco

card in standalone mode.

•

Dedicated—The 10/100 management port is used to access the CIMC. You must select a NIC

redundancy and IP setting.

Shared LOM—The 1-Gb Ethernet ports are used to access the CIMC. You must select a NIC

redundancy and IP setting.

Cisco Card—The ports on an installed Cisco UCS virtual interface card (VIC) are used to access the

CIMC. You must select a NIC redundancy and IP setting.

Note

Cisco Card NIC mode is currently supported only with a Cisco UCS VIC that is installed in PCIe

slot 1, 4, or 7. See also Special Considerations for Cisco UCS Virtual Interface Cards, page 3-45.

d. Use this utility to change the NIC redundancy to your preference. This server has three possible NIC

redundancy settings:

–

None—(Available only with the Shipping NIC mode) The Ethernet ports operate independently

and do not fail over if there is a problem.

–

Active-standby—If an active Ethernet port fails, traffic fails over to a standby port.

Active-active—All Ethernet ports are used simultaneously. See NIC Modes and NIC

Redundancy Settings, page 2-11 for more information.

e. Choose whether to enable DHCP for dynamic network settings, or to enter static network settings.

Note

Before you enable DHCP, your DHCP server must be preconfigured with the range of MAC

addresses for this server. The MAC address is printed on a label on the rear of the server. This

server has a range of six MAC addresses that are assigned to the CIMC. The MAC address

printed on the label is the beginning of the range of six contiguous MAC addresses.

f. (Optional) Use this utility to make VLAN settings, and to set a default CIMC user password.

Note

Changes to the settings take effect after approximately 45 seconds. Press F5 to refresh the screen

and wait until the new settings appear before you reboot the server in the next step.

g. Press F10 to save your settings and reboot the server.

Chapter 2 Installing the Server

Initial Server Setup

Note

If you chose to enable DHCP, the dynamically assigned IP and MAC addresses are displayed on

the console screen during bootup.

Step 5

Use a browser and the IP address of the CIMC to connect to the CIMC Setup Utility. The IP address is

based upon the settings that you made in Step 4 (either a static address or the address assigned by your

DHCP server).

Note

The default user name for the server is admin. The default password is password.

To manage the server, see the Cisco UCS C-Series Rack-Mount Server Configuration Guide or the Cisco

UCS C-Series Rack-Mount Server CLI Configuration Guide for instructions on using those interfaces.

NIC Modes and NIC Redundancy Settings

This server has the following NIC mode settings that you can choose from:

•

Shared LOM EXT (default)—This is shared LOM extended mode. This is the factory default setting,

along with Active-active NIC redundancy and DHCP-enabled. With this mode, the shared LOM and

Cisco Card interfaces are both enabled.

Note

In this mode, DHCP replies are returned to both the shared LOM ports and the Cisco card ports.

If the system determines that the Cisco card connection is not getting its IP address from a Cisco

UCS Manager system because the server is in standalone mode, further DHCP requests from the

Cisco card are disabled. If the system determines that the Cisco card connection is getting its IP

address from a Cisco UCS Manager system, the reply has parameters that automatically move

the server to UCSM mode.

•

Dedicated—The 10/100 management port is used to access the CIMC. You must select a NIC

redundancy and IP setting.

Shared LOM—The 1-Gb Ethernet ports are used to access the CIMC. You must select a NIC

redundancy and IP setting.

Cisco Card—The ports on an installed Cisco UCS virtual interface card (VIC) are used to access the

CIMC. You must select a NIC redundancy and IP setting.

Note

The Cisco Card NIC mode is currently supported only with a Cisco UCS VIC that is installed in

PCIe slot 1, 4, or 7. See also Special Considerations for Cisco UCS Virtual Interface Cards,

page 3-45.

This server has the following NIC redundancy settings that you can choose from:

•

None—The Ethernet ports operate independently and do not fail over if there is a problem.

Active-standby—If an active Ethernet port fails, traffic fails over to a standby port.

Active-active—All Ethernet ports are used simultaneously.

The active/active setting uses Mode 5 or Balance-TLB (adaptive transmit load balancing). This is

channel bonding that does not require any special switch support. The outgoing traffic is distributed

according to the current load (computed relative to the speed) on each slave. Incoming traffic is

received by the current slave. If the receiving slave fails, another slave takes over the MAC address

of the failed receiving slave.

Chapter 2 Installing the Server

Service DIP Switch

Using the BIOS Recovery DIP Switch

Depending on which stage the BIOS becomes corrupted, you might see different behavior.

•

If the BIOS BootBlock is corrupted, you might see the system get stuck on the following message:

Initializing and configuring memory/hardware

•

If it is a non-BootBlock corruption, the following message is displayed:

****BIOS FLASH IMAGE CORRUPTED****

Flash a valid BIOS capsule file using CIMC WebGUI or CLI interface.

IF CIMC INTERFACE IS NOT AVAILABLE, FOLLOW THE STEPS MENTIONED BELOW.

1. Connect the USB stick with recovery.cap file in root folder.

2. Reset the host.

IF THESE STEPS DO NOT RECOVER THE BIOS

1. Power off the system.

2. Mount recovery jumper.

3. Connect the USB stick with recovery.cap file in root folder.

4. Power on the system.

Wait for a few seconds if already plugged in the USB stick.

REFER TO SYSTEM MANUAL FOR ANY ISSUES.

Note

As indicated by the message shown above, there are two procedures for recovering the BIOS. Try

procedure 1 first, then if that does not recover the BIOS, use procedure 2.

The server must have CIMC version 1.4(6) or later to use these procedures.

Procedure 1: Reboot With recovery.cap File

Step 1

Step 2

Download the BIOS update package and extract it to a temporary location.

Copy the contents of the extracted recovery folder to the root directory a USB thumb drive. The

recovery folder contains the recovery.capfile that is required in this procedure.

Note

The recovery.capfile must be in the root directory of the USB thumb drive. Do not rename this

file. The USB thumb drive must be formatted with either FAT16 or FAT32 file systems.

Step 3

Step 4

Step 5

Insert the USB thumb drive into a USB port on the server.

Reboot the server.

Return the server to main power mode by pressing the Power button on the front panel.

The server boots with the updated BIOS boot block. When the BIOS detects a valid recovery.capfile

on the USB thumb drive, it displays this message:

Found a valid recovery file...Transferring to CIMC

System would flash the BIOS image now...

System would restart with recovered image after a few seconds...

Step 6

Wait for server to complete the BIOS update, then remove the USB thumb drive from the server.

Note

During the BIOS update, the CIMC will shut down the server and the screen will be blank for

about 10 minutes. Do not unplug the power cords during this update. The CIMC will power on

the server after the update is complete.

Shutting Down and Powering Off the Server

The server can run in two power modes:

•

Main power mode—Power is supplied to all server components and any operating system on your

hard drives can run.

Standby power mode—Power is supplied only to the service processor and the cooling fans and it

is safe to power off the server from this mode.

You can invoke a graceful shutdown or a hard shutdown by using either the CIMC management interface

or the Power button on the front panel.

To use the Power button, follow these steps:

Step 1

Check the color of the Power Status LED (see the “Front-Panel LEDs” section on page 3-2).

•

Green—The server is in main power mode and must be shut down before it can be safely powered

off. Go to Step 2.

•

Drive Population Guidelines

The server can operate with one or two drive bay modules. Each drive bay module can hold up to eight

2.5-inch drives for a total of 16 drives. Figure 3-6 shows the drive bay modules and the drive bay

numbering.

Figure 3-6

Drive Bay Modules and Drive Bay Numbering

Drive bay module 1

Drive bay module 2

Observe these drive population guidelines for optimum performance:

•

When populating drives in a drive bay module, add drives in empty slots from left to right.

If your server has two drive bay modules, populate all eight bays in module 1 before you populate

the module 2 bays.

•

Keep an empty drive blanking tray in any unused slots to ensure proper airflow.

You can mix hard drives and SSDs in the same server. However, you cannot configure a logical

volume (virtual drive) that contains a mix of hard drives and SSDs. When you create a logical

volume, it must contain all hard drives or all SSDs.

Chapter 3 Maintaining the Server

Installing or Replacing Server Components

Replacing a Modular Drive Bay Assembly

The server allows modular configuration of the drive bays, so that you can use one or two drive bays

depending on your needs.

Each drive bay assembly includes the chassis-steel drive bay, the attached drive backplane, and a

transition card (expander or nonexpander version) that provides a connection to your RAID controllers

and the motherboard.

•

Each of the two modular chassis drive bays can hold up to eight 2.5-inch drives.

Each drive backplane connects to one transition card. The transition card connects the drive

backplane to the motherboard and connects to cables from your RAID controller.

•

The transition card is available in two versions:

–

Nonexpander—Two internal connections to the RAID controller card are required to control

eight drives. This version includes two connectors for the cables from your RAID controller.

One connector allows control of drives 1 through 4 on the backplane. The other connector

allows control of drives 5 through 8 on the backplane.

–

Expander—One internal connection to the RAID controller card is required to control eight

drives. This one connector allows control of drives 1 through 8 on the backplane.

•

To use more than eight 2.5-inch drives in the server (up to 16), two drive bay modules are required,

each with its own backplane and transition card.

DIMM Population Rules

Observe the following guidelines when installing or replacing DIMMs (see Figure 3-13):

•

The minimum configuration is one DIMM installed in any of CPU1’s blue sockets (A1, B1, C1, D1).

When populating a channel, fill the blue socket first, and then fill the black sockets (1, 2, 3).

The server supports one, two, or three DIMMs per channel for single- or dual-rank DIMMs.

The server supports only one or two quad-rank registered DIMMs (RDIMMs) per channel. The

server supports one, two, or three quad-rank load-reduced DIMMs (LRDIMMs) per channel.

•

The server supports RDIMMs or LRDIMMs. Do not mix RDIMMs and LRDIMMs in a server.

Unregistered DIMMs (UDIMMs) and non-ECC DIMMs are not supported.

For memory mirroring population rules, see Memory Mirroring Mode, page 3-25.

There is no requirement to install DIMMs evenly across all CPUs. However, for optimal

performance, you should populate sockets in the order that is shown in Table 3-4 for two-CPU

systems or Table 3-5 for four-CPU systems.

Installing or Replacing Server Components

Memory Mirroring Mode

Note

You cannot use memory sparing and memory mirroring at the same time.

When you enable memory mirroring mode, the memory subsystem simultaneously writes identical data

to two channels. If a memory read from one of the channels returns incorrect data due to an uncorrectable

memory error, the system automatically retrieves the data from the other channel. A transient or soft

error in one channel does not affect the mirrored data, and operation continues.

Memory mirroring reduces the amount of memory available to the operating system by 50 percent

because only one of the two populated channels provides data.

If you choose to enable memory mirroring, you must install sets of identical DIMMs as follows:

•

For a two-CPU system, you must install DIMMs in identical sets of four. Use each set of four

identical DIMMs to populate the sockets in the order shown in Table 3-4.

•

For a four-CPU system, you must install DIMMs in identical sets of eight. Use each set of eight

identical DIMMs to populate the DIMM sockets in the order shown in Table 3-5.

Lockstep Channel Mode

When you enable lockstep channel mode, each memory access is a 128-bit data access that spans four

channels.

Lockstep channel mode requires that all four memory channels on a CPU must be populated identically

with regards to size and organization. DIMM socket populations within a channel do not have to be

identical but the same DIMM slot location across all four channels must be populated the same.

For example, DIMMs in sockets A1, B1, C1, and D1 must be identical. DIMMs in sockets A2, B2, C2,

and D2 must be identical. However, the A1-B1-C1-D1 DIMMs do not have to be identical with the

A2-B2-C2-D2 DIMMs.

If you choose to enable lockstep channel mode, you must install sets of identical DIMMs as follows:

•

For a two-CPU system, you must install DIMMs in identical sets of four. Use each set of four

identical DIMMs to populate the sockets in the order shown in Table 3-4.

•

For a four-CPU system, you must install DIMMs in identical sets of eight. Use each set of eight

identical DIMMs to populate the DIMM sockets in the order shown in Table 3-5.

Replacing CPUs and Heatsinks

The server supports up to four EP-Series CPUs. See Figure 3-13 on page 3-22 for the CPU socket

numbering.

•

The minimum configuration is two CPUs (CPU1 and CPU2).

The server must have either two or four CPUs to operate; you should populate CPU1 and CPU2 first,

and then populate CPU3 and CPU4.

This section contains the following topics:

•

Additional CPU-Related Parts To Order With RMA Replacement Motherboards, page 3-27

CPU Replacement Procedure, page 3-28

Additional CPU-Related Parts To Order With RMA Replacement Motherboards

When a return material authorization (RMA) of the motherboard or CPU is done on a Cisco UCS

C-series server, there are additional parts that might not be included with the CPU or motherboard spare

bill of materials (BOM). The TAC engineer might need to add the additional parts to the RMA to help

ensure a successful replacement.

•

Scenario 1—You are re-using the existing heatsinks:

–

Heat sink cleaning kit (UCSX-HSCK=)

Thermal grease kit for C420 (UCS-CPU-GREASE=)

Intel CPU Pick-n-Place tool for EP CPUs (UCS-CPU-EP-PNP=)

•

Scenario 2—You are replacing the existing heatsinks:

–

Heat sink (UCSC-HS-C420M3=)

Heat sink cleaning kit (UCSX-HSCK=)

Intel CPU Pick-n-Place tool for EP CPUs (UCS-CPU-EP-PNP=)

A CPU heatsink cleaning kit is good for up to four CPU and heatsink cleanings. The cleaning kit contains

two bottles of solution, one to clean the CPU and heatsink of old thermal interface material and the other

to prepare the surface of the heatsink.

New heatsink spares have preinstalled thermal interface material covered by a small sheet of plastic. It

is important to clean the old thermal interface material off of the CPU prior to installing the heatsinks.

Therefore, when ordering new heatsinks it is still necessary to order the heatsink cleaning kit at a

minimum.

Replacing a PCIe Card

Caution

Cisco supports all PCIe cards qualified and sold by Cisco. PCIe cards that are not qualified or sold by

Cisco are the responsibility of the customer. Although Cisco always stands behind and supports the

C-Series rack-mount servers, customers using standard, off-the-shelf, third-party cards must go to the

third-party card vendor for support if any issue with that particular third-party card occurs.

This server has seven PCIe expansion slots. See Figure 3-23 and Table 3-6 for information about the

slots. The replacement procedures differ depending on whether the PCIe slot is in a riser or on the

motherboard. This section includes the following topics:

Chapter 3 Maintaining the Server

Installing or Replacing Server Components

Installing Multiple PCIe Cards and Resolving Limited Resources

When a large number of PCIe add-on cards are installed in the server, the system might run out of the

following resources required for PCIe devices:

•

Option ROM memory space

16-bit I/O space

The topics in this section provide guidelines for resolving the issues related to these limited resources:

•

Resolving Insufficient Memory Space to Execute Option ROMs, page 3-46

Resolving Insufficient 16-Bit I/O Space, page 3-47

Resolving Insufficient Memory Space to Execute Option ROMs

The system has very limited memory to execute PCIe legacy option ROMs, so when a large number of

PCIe add-on cards are installed in the server, the system BIOS might not able to execute all of the option

ROMs. The system BIOS loads and executes the option ROMs in the order that the PCIe cards are

enumerated (slot 1, slot 2, slot 3, and so on).

If the system BIOS does not have sufficient memory space to load any PCIe option ROM, it skips loading

that option ROM, reports a system event log (SEL) event to the CIMC controller, and reports the

following error in the Error Manager page of the BIOS Setup utility:

PCI OUT OF RESOURCES CONDITION:

ERROR: Insufficient PCI Resources Detected!!!

System is running with Insufficient PCI Resources!

In order to display this message some

PCI devices were set to disabled state!

It is strongly recommended to power off the system

and remove some PCI/PCI Express cards from the system!

To continue booting, proceed to <Save & Exit> Menu Option

and select Boot Device or <Discard Changes and Exit>.

WARNING: If you choose to continue booting some Operating

Systems might not be able to complete boot correctly!

To resolve this issue, disable the option ROMs that are not needed for system booting. The BIOS Setup

Utility provides the setup options to enable or disable the option ROMs at the PCIe slot level for the

PCIe expansion slots and at the port level for the onboard NICs. These options can be found in the BIOS

Setup Utility Advanced →PCI Configuration page (see Figure 3-26).

Guidelines for RAID controller booting

When the server is configured in the factory, the RAID controllers are installed in PCIe slot 3 or

slot 5 for single RAID controller configuration, or in both slot 3 and slot 5 for dual RAID controller

configuration.

If the server is configured to boot primarily from RAID storage, make sure that the option ROMs

for slot 3 or slot 5 are enabled in the BIOS, depending upon your RAID controller configuration. If

the RAID controller does not appear in the system boot order even with the option ROMs for slot 3

and slot 5 enabled, the RAID controller option ROM might not have sufficient memory space to

execute. In that case, disable other option ROMs that are not needed for the system configuration to

free up some memory space for the RAID controller option ROM.

•

Guidelines for onboard NIC PXE booting

If the system is configured to primarily perform PXE boot from onboard NICs, make sure that the

option ROMs for the onboard NICs to be booted from are enabled in the BIOS Setup Utility. Disable

other option ROMs that are not needed to create sufficient memory space for the onboard NICs PXE

boot.

Resolving Insufficient 16-Bit I/O Space

The system has only 64 KB of legacy 16-bit I/O resources available. This 64 KB of I/O space is divided

between four CPUs in the system because the PCIe controller is integrated into the CPUs. This server

BIOS has the capability to dynamically detect the 16-bit I/O resource requirement for each CPU and then

balance the 16-bit I/O resource allocation between the CPUs accordingly during the PCI bus

enumeration phase of the BIOS POST.

Chapter 3 Maintaining the Server

Installing or Replacing Server Components

When a large number of PCIe cards are installed in the system, the system BIOS might not have

sufficient I/O space for some PCIe devices. If the system BIOS is not able to allocate the required I/O

resources for any PCIe devices, the following symptoms have been observed:

•

The system might get stuck in an infinite reset loop.

The BIOS might appear to hang while initializing PCIe devices.

The PCIe option ROMs might take excessive time to complete, which appears to lock up the system.

PCIe boot devices might not be accessible from the BIOS.

PCIe option ROMs might report initialization errors. These errors are seen before the BIOS passes

control to the operating system.

•

The keyboard might not work.

To work around this problem, rebalance the 16-bit I/O load using the following methods:

1. Physically remove any unused PCIe cards.

2. If the system has one or more Cisco virtual interface cards (VICs) installed, disable the PXE boot

on the VICs that are not required for the system boot configuration by using the Network Adapters

page in the CIMC WebUI to free up some 16-bit I/O resources. Each VIC uses a minimum 16 KB

of 16-bit I/O resource, so disabling PXE boot on Cisco VICs would free up some 16-bit I/O

resources that can be used for other PCIe cards that are installed in the system.

Uncheck the “Enable PXE boot entry” in the vNIC properties dialog to disable the PXE boot, as

shown in Figure 3-27.

Enabling the Intel Trusted Execution Technology Feature For the TPM

Intel Trusted Execution Technology (TXT) provides greater protection for information that is used and

stored on the business server. A key aspect of that protection is the provision of an isolated execution

environment and associated sections of memory where operations can be conducted on sensitive data,

invisibly to the rest of the system. Intel TXT provides for a sealed portion of storage where sensitive

data such as encryption keys can be kept, helping to shield them from being compromised during an

attack by malicious code.

To enable the TXT feature, follow these steps:

Chapter 3 Maintaining the Server

Installing or Replacing Server Components

Replacing Power Supplies

The server can have one or two power supplies. When two power supplies are installed they are

redundant as 1+1.

To replace or install a power supply, follow these steps:

Note

If you have ordered a server with power supply redundancy (two power supplies), you do not have to

power off the server to replace power supplies because they are redundant as 1+1.

Step 1

Remove the power supply that you are replacing or a blank panel from an empty bay (see Figure 3-30):

a. Perform one of the following actions:

–

If your server has only one power supply, shut down and power off the server as described in

the “Shutting Down and Powering Off the Server” section on page 3-8.

–

If your server has two power supplies, you do not have to shut down the server.

b. Remove the power cord from the power supply that you are replacing.

c. Grasp the power supply handle while pinching the release lever towards the handle.

d. Pull the power supply out of the bay.

Step 2

Install a new power supply:

a. Grasp the power supply handle and insert the new power supply into the empty bay.

b. Push the power supply into the bay until the release lever locks.

c. Connect the power cord to the new power supply.

d. If you shut down the server, press the Power button to return the server to main power mode.

Supercap Power Modules (RAID Backup Units)

This server supports installation of two supercap power module (SCPM) backup units. The units mount

to trays on the removable air baffle (see Replacing the Supercap Power Module (RAID Backup Unit),

page 3-49).

The SCPM is available only when using the LSI MegaRAID-CV controller cards. This module provides

approximately 3 years of backup for the disk write-back cache DRAM in the case of sudden power loss

by offloading the cache to the NAND flash.

Mixing Drive Types in RAID Groups

Table C-2 lists the technical capabilities for mixing hard disk drive (HDD) and solid state drive (SSD)

types in a RAID group. However, see the best practices recommendations that follow for the best

performance.

Table C-2

Drive Type Mixing in RAID Groups

Mix of Drive Types

Best Practices For Mixing Drive Types in RAID Groups

For the best performance, follow these guidelines:

•

Use either all SAS or all SATA drives in a RAID group.

Use the same capacity for each drive in the RAID group.

Never mix HDDs and SSDs in the same RAID group.

RAID Controller Cabling

The maximum two supported RAID controller cards should be populated in PCIe slots in the following

order (see Figure 3-23 on page 3-40):

1. PCIe slot 3

2. PCIe slot 5

Refer to the following examples for cable routing guidelines:

•

Example 1—One Nonexpander and One RAID Controller with Eight Drives, page C-3

Example 2—Two Nonexpanders and Two RAID Controllers with 16 Drives, page C-4

Example 3—Two Expanders and One RAID Controller with Sixteen Drives, page C-5

Appendix C RAID Controller Considerations

Restoring RAID Configuration After Replacing a RAID Controller

When you replace a RAID controller, the RAID configuration that is stored in the controller is lost.

To restore your RAID configuration to your new RAID controller, follow these steps.

Step 1

Step 2

Replace your RAID controller. See Replacing a PCIe Card in a Motherboard Slot, page 3-43.

If this was a full chassis swap, replace all drives into the drive bays, in the same order that they were

installed in the old chassis.

Step 3

Note

Reboot the server and watch for the prompt to press F.

For newer RAID controllers, you are not prompted to press F. Instead, the RAID configuration is

imported automatically. In this case, skip to Step 6.

Step 4

Step 5

Press F when you see the following onscreen prompt:

Foreign configuration(s) found on adapter.

Press any key to continue or ‘C’ load the configuration utility,

or ‘F’ to import foreign configuration(s) and continue.

Press any key (other than C) to continue when you see the following onscreen prompt:

All of the disks from your previous configuration are gone. If this is

an unexpected message, then please power of your system and check your cables

to ensure all disks are present.

Press any key to continue, or ‘C’ to load the configuration utility.

Step 6

Watch the subsequent screens for confirmation that your RAID configuration was imported correctly:

•

If you see the following message, your configuration was successfully imported. The LSI virtual

drive is also listed among the storage devices.

N Virtual Drive(s) found on host adapter.

•

If you see the following message, your configuration was not imported. This problem can occur if

you do not press F quickly enough when prompted. In this case, reboot the server and try the import

operation again when you are prompted to press F.

0 Virtual Drive(s) found on host adapter.

For More Information

The LSI utilities have help documentation for more information about using the utilities.

For basic information about RAID and for using the utilities for the RAID controller cards, see the

Cisco UCS Servers RAID Guide.
