Logical Drive and LUN Numbering Strategy
Logical Drive and LUN Numbering Strategy
A suggested strategy is to create a logical drive for each blade server. Each
logical drive has its own LUN. The LUN is 0 so the blade server can boot from it.

Prerequisites
The Modular Server-to-VTrak connection requires:
•
•
•
Modular Server, setup and running with a network connection
VTrak, setup and running with a network connection
Networked PC workstation running Windows OS, to access Module Server
Control and WebPAM PROe
•
•
SAS cable with SFF-8088 Mini-SAS external connectors. The cable must be
long enough to reach from your Modular Server to your VTrak.

Task 2: Enabling External Ports
The Modular Server has external ports that each blade server can access. The
port numbers correspond to the slot number of each blade server. To enable a
port is to enable the external data connection, in this case, to access a LUN on
the VTrak.
To enable the external ports:
1. In the MSC screen, click the Chassis Back tab.
2. Click the SCM 1 component in the enclosure graphic.
3. Click Expansion Port in the SCM 1 Actions menu.

Express – You choose the RAID characteristics and type of application.
Creates a disk array and logical drives based on your input. Faster.
•
Advanced – You specify all parameters for the disk array and logical drives.
One logical drive will be created automatically. You can create additional
logical drives now or at a later time. More options. See page 14.

Task 7: Associating LUNs and Initiators
A LUN represents a logical drive on the VTrak. An initiator represents a blade
server in the Modular Server. Each blade server uses LUN0 for booting and
storage. This task includes the following actions:
•
•

Task 8: Installing an OS on a Blade Server
Task 8: Installing an OS on a Blade Server
In this case, the phrase installing an OS on a blade server refers to installing the
OS onto the VTrak LUN assigned to the blade server.
Connections required to boot the blade server and install the OS are made
through the 15-pin video connector and two USB connectors on the front panel.
This procedure requires a monitor, keyboard, mouse, and an external CD drive
with a USB 2.0 interface.
To install an OS on a blade server:
1. Power off the blade server.
Press the power button on the front panel. See Figure 8.
2. Attach a monitor, keyboard and mouse, and CD drive to the blade server.
3. Power on the monitor, CD drive, and blade server.
To power on the blade server, press the power button on the front panel. See
4. Insert the OS installer CD in the CD drive.
5. Follow the prompts for OS installation.
Be sure you install the OS onto LUN 0.
6. Reboot the blade server.
7. Enter BIOS setup and set the boot order to boot from LUN 0 first.
8. Exit the BIOS setup.
This completes OS installation on this blade server. Repeat the installation on
your other blade servers as required.
Within Windows, you might have to bring the physical drives online to enable
them.
