Hardware Components  
1 Processor:  
QLogic’s ISP  
contains a RISC  
processor.  
5
NVRAM: Non-Volatile Random Access Memory (aka  
EEPROM). Where some of the adapter parameter  
settings are stored. Because NVRAM is a non-volatile  
type of RAM, data is retained even if the power is shut off.  
2
SRAM: Static  
Random Access  
memory. Where  
the firmware is  
loaded. In  
addition to the  
firmware, SRAM  
also retains (in  
queue) the  
various I/O  
commands the  
Fibre Channel  
processor must  
process.  
Transceivers:  
Short for  
transmitter-  
receiver, a  
device (copper  
or optical) that  
transmits and  
receives signals.  
LEDs: Light Emitting Diodes. Display various  
active/inactive states of an adapter. QLogic’s  
Beaconing feature uses LEDs to identify the  
physical location of the adapter.  
Flash: Non-volatile  
form of memory.  
Where the boot code  
is stored.

The reduced instruction set computer (RISC) processor, also known as the intelligent stor-  
age peripheral (ISP) controller, is the heart of the adapter. The RISC processor is a single  
integrated ASIC (application specific integrated circuit) that contains the processing power  
required to run the Fibre Channel and FCoE protocols. The RISC processor also interfaces  
the host bus (PCI-X or PCI Express) and controls the I/O operations.  
The static random access memory (SRAM) provides the runtime memory required for the  
adapter operations. The SRAM is where the firmware is downloaded when the adapter is  
powered up. The RISC processor (see 1) accesses the SRAM to process the firmware  
instructions. In addition, the SRAM stores the runtime context of various I/O operations in  
progress.  
The non-volatile memory, also referred to as Flash memory, contains the boot code run by  
the RISC processor (see 1) when the adapter is powered up. On QLogic Fibre Channel  
Adapter 2400 series and later, the Flash memory contains multiple boot images—the  
FCode, x86 BIOS, and EFI—to support multi-boot capability on different platforms.

LEDs indicate the real-time status of the adapter, Fibre Channel or Ethernet link status, and  
link activity. LED patterns are described in detail in “Troubleshooting with LEDs” on  
page A-1.

Non-volatile random access memory (NVRAM) is used to store the per-port adapter config-  
uration parameters. These parameters are typically loaded at manufacturing and should  
not be modified except by those who have an expert level understanding of the functioning  
of QLogic Fibre Channel and Converged Network Adapters. During adapter initialization,  
the parameters are accessed and used to configure the adapter. Examples of adapter con-  
figuration parameters include Fibre Channel connection type (topology), Fibre Channel  
data rate, Fibre Channel tape support, and so on.  
Software Components  
This section describes the following QLogic adapter software components:  
Boot Code  
OS Driver  
„
„
„
„
Firmware  
Management Tools and Utilities  
Boot Code  
Boot code resides on the Flash memory on the adapter. The primary function of  
the boot code is to communicate with an external boot device before the operating  
system takes the control over when booting from a storage device attached to the  
QLogic adapter. This type of configuration is referred to as boot from SAN.  
OS Driver  
For all QLogic Fibre Channel Adapters currently supported on VMware ESX/ESXi  
4.0, the driver is supported natively with ESX; that is, no separate driver  
installation is required for VMware ESX/ESXi 4.0 to recognize the QLogic Fibre  
Channel Adapters. QLogic Fibre Channel Adapters on VMware ESX/ESXi 4.0  
require no additional driver installation steps to run the adapters. In some specific  
cases, you may need to download from the VMware Web site one of the following:  
„

1–Hardware and Software Components  
Supported QLogic Adapters  
NOTE:  
All inbox drivers for ESX/ESXi are distributed by VMware.  
Firmware  
The firmware module performs most of the Fibre Channel and FCoE  
protocol-related functions, thus freeing the system CPU and memory resources  
from protocol processing. This efficiency keeps the QLogic Fibre Channel and  
Converged Network Adapter drivers thin, which saves runtime system resources  
such as CPU and memory.  
The QLogic Fibre Channel and Converged Network Adapter firmware is bundled  
with the driver. For the QLE8000 Series Converged Network Adapters, the FCoE  
Engine (framer) firmware is resident on the adapter. The FCoE firmware for the  
adapter is also bundled with the driver.  
Management Tools and Utilities  
QLogic offers a comprehensive suite of management tools and utilities, including  
the following:  
„
„
SANsurfer FC HBA Manager provides a graphical user interface for  
simplified management.  
SANsurfer FC HBA CLI (command line interface) enables you to automate  
Fibre Channel Adapter management by means of scripting and interactive  
mode.  
Supported QLogic Adapters  
For a complete list of QLogic Fibre Channel and Converged Network Adapters  
supported on VMware ESX/ESXi 4.0, refer to the online VMware Hardware  
Compatibility Guide located here:

2–Installation  
Installing SANsurfer Management Tools  
Installing SANsurfer FC HBA Manager  
To run SANsurfer FC HBA Manager on a VMware ESX 4.0 server requires a  
two-step installation process, whereby:  
1.  
2.  
You must install the SANsurfer back end, commonly called the qlremote  
agent, on the ESX server.  
You must download the SANsurfer FC HBA Manager GUI from the QLogic  
Web site and install it on a Windows® or Linux® system. SANsurfer FC HBA  
Manager allows you to remotely manage QLogic adapters.  
After SANsurfer FC HBA Manager is installed, you must connect it to the qlremote  
agent using the IP address or host name of the ESX host on which the qlremote  
agent is installed. When SANsurfer FC HBA Manager is connected to the  
qlremote agent, you can use it to view and manage the QLogic adapters.  
NOTE:  
„ You must have the ESX agent from the ESX VMware downloaded  
package.  
„ The SANsurfer FC HBA Manager for Linux downloaded packages can  
be installed on any Windows or Linux box that has LAN access to the  
ESX server, depending on which server the you want to manage the  
ESX server.  
NOTE:  
The qlremote agent requires a service called portmap running on the ESX  
4.0 host. To turn on the portmap service, execute the following commands  
on the ESX 4.0 Server Console:  
# chkconfig firewall off  
# esxcfg-firewall --allowIncoming --allowOutgoing  
# chkconfig portmap on  
# service portmap start  
# service iptables stop  
SANsurfer FC HBA Manager requires that you select the download link to the  
package for your operating system from the QLogic Web site.

Deploying NPIV for VMware ESX/ESXi 4.0  
QLogic Fibre Channel and Converged Network Adapters support N_Port ID  
virtualization (NPIV) for Fibre Channel and FCoE SANs. NPIV enables each  
virtual machine to have its own Fibre Channel-FCoE world wide port name  
(WWPN) by creating multiple virtual adapters on a single physical adapter.

3–Configuration  
Monitoring NPIV Virtual Ports from SANsurfer  
VMware ESX/ESXi 4.0 enables NPIV support on QLogic 4Gb/8Gb Fibre Channel  
Adapters and QLE8000 Series Converged Network Adapters. No additional  
software or hardware installation is required to support NPIV. Note that VMware  
ESX/ESXi 4.0 supports NPIV only on RDM (Raw Device Mapping) devices.  
To configure NPIV, the Fibre Channel-FCoE switch port must be configured to  
enable NPIV. The specific procedure to enable NPIV on the switch port depends  
on the switch itself. For details, refer to the Fibre Channel-FCoE switch  
documentation.  
For more detailed NPIV information, refer to the following documents available  
from VMware:

http://www.vmware.com/pdf/vi3_35_25_npiv_config.pdf (information is also  
applicable to ESX 4.0)  
Monitoring NPIV Virtual Ports from SANsurfer  
QLogic’s SANsurfer management tools also support the NPIV functionality in the  
drivers. SANsurfer FC HBA Manager (GUI) and SANsurfer FC HBA CLI  
(command line interface) both display the virtual ports configured on the system.  
SANsurfer management tools also provide additional information on the virtual  
ports, including diagnostics and monitoring information.  
SANsurfer generates events and notifies the user of any change (such as virtual  
port creation and deletion) at the backend to the virtual ports.  
Figure 3-4 shows a typical virtual environment in SANsurfer FC HBA Manager  
with physical and virtual ports. The proc node provides information on the number  
of virtual ports and their individual states, as well as the target devices with which  
they can communicate (see also “Using Console OS” on page 3-2).

Configuring Boot from SAN  
Boot from SAN refers to installing and booting a server’s operating system from a  
storage device attached to the SAN instead of from a locally attached storage  
device. The OS is installed on one or more LUNs in the SAN array and the Fibre  
Channel and Converged Network Adapters are configured to boot from the  
specified LUN. Boot from SAN providers several benefits including:  
„
„
„
„
Reducing server costs  
Ease of management  
Improved disaster tolerance  
Improved boot LUN availability

Troubleshooting with LEDs  
QLogic Fibre Channel and Converged Network Adapters have LEDs that can help  
you diagnose problems. Typically, administrators observe the LED patterns to  
perform first-level troubleshooting that can indicate some obvious firmware or  
hardware issues.  
Specific QLogic Fibre Channel and Converged Network Adapter families have  
unique LED patterns. The following tables describe the LED patterns for the  
various Fibre Channel and Converged Network Adapter series.

Dynamic Extended Logging  
The QLogic driver provides a mechanism to dynamically enable extended error  
logging about driver operation. These logs provide debugging and error  
information to help you understand driver behavior regarding issues related to the  
adapter. These logs are saved in a system log file named vmkernel, in the  
/var/log/directory.  
To enable extended error logging, execute the following command:  
# echo "scsi-qlaenable-log" > /proc/scsi/qla2xxx/<adapter_number>  
To disable extended error logging, execute the following command:  
# echo "scsi-qladisable-log" > /proc/scsi/qla2xxx/<adapter_number>

A–Troubleshooting  
Troubleshooting with Driver Logs  
When the logging is enabled, the driver version in the  
/proc/scsi/qla2xxx/<adapter number>is appended with a -debugflag  
as shown below:  
# cat /proc/scsi/qla2xxx/5  
QLogic PCI to Fibre Channel Host Adapter for QLE2462:  
Firmware version 4.04.09 [IP] [Multi-ID] [84XX], Driver  
version 8.02.01-k1-vmw41-debug  
BIOS version 2.10  
FCODE version 2.04  
EFI version 2.04  
Flash FW version 4.06.02  
ISP: ISP2432  
NOTE:  
Although the driver logs provide debugging and error information, they also  
increase I/O latency. Therefore, QLogic does not recommend that you  
enable extended logging during normal operations.  
Troubleshooting with Driver Logs  
All messages from the QLogic Fibre Channel Adapter driver are logged in  
/var/log/vmkernel. These messages provide additional information about the  
driver operation: both normal and driver warnings. Messages from the driver are  
usually preceded by scsi(%d), where %d is the adapter instance number.

Boot code for QLogic Fibre Channel  
Adapters is required if the computer  
system is booting from a storage device  
(disk drive) attached to the adapter. The  
primary function of the boot code is  
communication with the external boot  
device before the operating system is up  
and running. Boot code can also perform  
secondary functions, including managing  
the setup for the adapter and initializing  
and testing the adapter's ISP.

The ability for each server on a network to  
boot their operating system from a Fibre

switch that connects to another Fibre  
Channel switch or bridge device by an  
inter-switch link ISL). E_Ports are used to  
link Fibre Channel switches to form a  
multi-switch fabric.  
Cache contents duplicate recently-used  
values stored on disk or elsewhere. Cache  
is quick to access relative to the original  
data which either takes more time due to  
slow disc-access time, or is slow to  
compute. After data is stored in the cache,  
future use can be made by accessing the  
cached copy rather than re-finding or  
recomputing the original data, so that the  
average access time is lower.  
Enhanced Ethernet  
Also called data center Ethernet or  
converged enhanced Ethernet. Refers to  
new enhancements to the existing  
Ethernet standard that eliminate  
Ethernet’s inherent lossy nature and make  
10Gb Ethernet a viable storage networking  
transport.  
„ L1 cache—Primary (smallest) cache  
Ethernet  
on the same chip as the processor.  
The most widely used LAN technology that  
transmits information between computers,  
typically at speeds of 10 and 100 million  
bits per second (Mbps).  
„ L2 cache—Secondary (larger) cache.  
Either on the processor chip or  
external to the processor.  
Converged Network Adapter

LUN  
Logical unit number, a subdivision of a  
Inter-switch link. The connection between  
two switches using E_Ports.  
SCSI target. It is the small integer handle  
that differentiates an individual disk drive  
or partition (volume) within a common  
SCSI target device such as a disk array.  
Intelligent storage peripheral. QLogic  
trademark and family of Fibre Channel and  
SCSI controller chips that replace network  
interface chips in network adapters,  
servers, and storage.  
Technically, a LUN can be a single  
physical disk drive, multiple physical disk  
drives, or a portion (volume) of a single  
physical disk drive. However, LUNs are  
typically not entire disk drives but rather  
virtual partitions (volumes) of a RAID set.  
LAN  
Local area network. Network typically with  
transmissions less than 5 km.  
Using LUNs, the Fibre Channel host can  
address multiple peripheral devices that  
may share a common controller.  
L_Port  
Loop port. Does arbitrated loop functions  
and protocols. NL_Ports and FL_Ports are  
examples of loop-capable ports. See  
E_Port, F_Port, FL_Port, G_Port, N_Port,  
NL_Port.  
media  
Physical-layer information carriers. Fibre  
Channel supports several different  
physical media: copper, multimode optical,  
and single-mode optical. All Fibre Channel  
protocols are supported on all media.  
LIP  
Loop initialization process. The initializa-  
tion process in an arbitrated loop that  
occurs when the loop is powered up or a  
new device is added. One function of a LIP  
is to assign addresses. All data transmis-  
sion on the loop is suspended during a LIP.  
message signaled interrupts  
See  
MSI/MSI-X  
Message signaled interrupts. An alternate  
way of generating an interrupts with  
special messages to allow PCI to emulate  
a pin assertion or deassertion. Message  
signaled interrupts allow the device to  
write a small amount of data to a special  
address in memory space. The chipset will  
deliver the corresponding interrupt to a  
CPU. MSI-X (defined in PCI 3.0) allows a  
larger number of interrupts (up to 2048),  
and gives each one a separate target  
address and data word.

N_Port  
Node port. A port that connects by a  
point-to-point link to either a single N_Port  
node port  
See N_Port.  
NPIV  
or a single F_Port. N_Ports handle  
creation, detection, and flow of message  
units to and from the connected systems.  
N_Ports are end ports in virtual  
point-to-point links through a fabric, for  
example N_Port to F_Port to F_Port to  
N_Port using a single Fibre Channel fabric  
switch. See also FL_Port.  
The ability for a single physical Fibre  
Channel end point (N_Port) to support  
multiple, uniquely addressable, logical end  
points. With NPIV, a host Fibre Channel  
Adapter is shared in such a way that each  
virtual adapter is assigned to a virtual  
server and is separately identifiable within  
the fabric. Connectivity and access privi-  
leges within the fabric are controlled by  
identification of each virtual adapter and,  
hence, the virtual server using each virtual  
adapter.  
N_Port ID virtualization  
See NPIV.  
NIC  
Network interface card or network inter-  
face controller. A computer circuit board or  
card that is installed in a computer so that  
it can be connected to a network.  
NVRAM  
Non-volatile random access memory. A  
type of memory that retains data (configu-  
ration settings) even when power is  
removed. You can manually configure  
NVRAM settings or restore them from a  
file.  
NL_Port  
Node loop port. A port capable of  
arbitrated loop functions and protocols. An  
NL_Port connects through an arbitrated  
loop to other NL_Port and at most a single  
FL_Port. NL_Ports handle creation, detec-  
tion, and flow of message units to and from  
the connected systems. NL_Ports are end  
ports in virtual point-to-point links through  
a fabric, for example NL_Port to F_Port to  
F_Port to N_Port using a single Fibre  
Channel fabric switch. In the absence of a  
fabric switch FL_Port, NL_Ports can  
communicate with other NL_Ports in  
virtual point-to-point links through a FC_AL  
open loop circuit often through FC_AL  
(arbitrated Loop) hub or loop switch  
devices. See: E_Port, F_Port, FL_Port,  
G_Port, N_Port.  
path  
A path to a device is a combination of a  
adapter port instance and a target port as  
distinct from internal paths in the fabric  
network. A fabric network appears to the  
operating system as an opaque network  
between the adapter (initiator) and the  
target.  
Because a path is a combination of an  
adapter and a target port, it is distinct from  
another path if it is accessed through a  
different adapter and/or it is accessing a  
different target port. Consequently, when  
switching from one path to another, the  
driver might be selecting a different  
adapter (initiator), a different target port, or  
both.

This is important to the driver when  
selecting the proper method of failover  
notification. It can make a difference to the  
target device, which might have to take  
different actions when receiving retries of  
the request from another initiator or on a  
different port.  
port login  
See PLOGI.  
reduced instruction set computer  
See RISC.  
registered state change notification  
See RSCN.  
PLOGI  
Port login. A port login occurs in a Fibre  
Channel SAN when two node ports estab-  
lish a connection between each other  
(typically a device such as a Fibre Channel  
Adapter connecting to a switch).  
RISC  
Reduced instruction set computer. A  
computer microprocessor that performs  
fewer types of computer instructions,  
thereby operating at higher speeds.  
point-to-point  
RSCN  
Also FC-P2P. Two Fibre Channel nodes  
directly connected (not in a loop).  
Registered state change notification  
(RSCN) is a Fibre Channel fabric notifica-  
tion sent to all specified nodes when any  
major fabric changes occur. This notifica-  
tion allows nodes to immediately gain  
knowledge about the fabric and react  
accordingly.  
port  
Access points in a device where a link  
attaches. The most common port types  
are:  
„ N_Port—a Fibre Channel port that  
SAN  
supports point-to-point topology.  
Storage area network. Multiple storage  
units (disk drives) and servers connected  
by networking topology.  
„ NL_Port—a Fibre Channel port that  
supports loop topology.  
„ F_Port—a port in a fabric where an  
N_Port can attach.  
SCSI  
„ FL_Port—a port in a fabric where an  
Small computer system interface. A  
high-speed interface used to connect  
devices—such as hard drives, CD drives,  
printers, and scanners— to a computer.  
The SCSI can connect many devices  
using a single controller. Each device is  
accessed by an individual identification  
number on the SCSI controller bus.  
NL_Port can attach.  
port instance  
The number of the port in the system.  
Each adapter may have one or multiple  
ports, identified with regard to the adapter  
as port 0, port 1 and so forth. to avoid  
confusion when dealing with a system  
containing numerous ports, each port is  
assigned a port instance number when the  
system boots up. So Port 0 on an adapter  
might have a port instance number of, for  
example, 8 if it is the eighth port discov-  
ered by the system.

target  
The storage-device endpoint of a SCSI  
session. Initiators request data from  
targets (usually disk-drives, tape-drives, or  
other media devices). Typically, a SCSI  
peripheral device is the target but an  
adapter may, in some cases, be a target. A  
target can contain many LUNs.  
A target is a device that responds to a  
request by an initiator (the host system).  
Peripherals are targets, but for some  
commands (for example, a SCSI COPY  
command), the peripheral may act as an  
initiator.

Transmission control protocol/Internet  
protocol. Basic communication language  
of the Internet.
