How To Perform a Boot From SAN Installation
Article: 127
Be sure the following prerequisites are met:
| • |
Only one path is active to the SAN. After the operating system and the multipathing software are installed, you can activate a second path. |
| • |
Only one LUN is presented to the target server. |
| • |
Review HP StorageWorks Booting Windows Systems from a Storage Area Network Application Notes and HP StorageWorks Booting Linux Systems from a Storage Area Network for details about SAN configuration and minimum firmware requirements. |
| 1. |
Configure the SAN storage for the target server.
| a. |
Run the appropriate platform Read HBA Configuration job from the Server Deployment Toolbox\1 - Hardware Configuration\HBA job folder on the target server.
This job creates the .\lib\hwconfig\hba\ID.ini file, where ID is the target server's computer ID. For example:
[HBA0]
WWID=500508b200713e72
HostAdapterBiosEnable=1
SelectBootEnable=1
BootDeviceWWID=
BootDeviceLUN=
[HBA1]
WWID=500508b200713e73
HostAdapterBiosEnable=0
SelectBootEnable=0
BootDeviceWWID=
BootDeviceLUN=
|
| b. |
Create a LUN for the boot volume of the target server. Record the created LUN and the WWID of the boot controller. |
| c. |
Using the target server HBA WWID from the file created in step 1a, configure the SAN switches for zoning or Selective Storage Presentation as needed in your environment. |
|
| 2. |
Configure the target server HBA to boot from the configured SAN storage.
| a. |
Edit the .\lib\hwconfig\hba\ID.ini file created in step 1a, adding the previously record boot controller WWID and LUN. For example:
[HBA0]
WWID=500508b200713e72
HostAdapterBiosEnable=1
SelectBootEnable=1
BootDeviceWWID=395442c135713a41
BootDeviceLUN=01
[HBA1]
WWID=500508b200713e73
HostAdapterBiosEnable=0
SelectBootEnable=0
BootDeviceWWID=395442c135713a42
BootDeviceLUN=01
|
| b. |
Run the appropriate platform Write HBA Configuration job from the Server Deployment Toolbox\1-Hardware Configuration\HBA job folder on the target server. |
| c. |
For ProLiant servers, run the Deploy ProLiant BL System Configuration (Boot From SAN) {LinuxPE} or {WinPE} job from the Server Deployment Toolbox\1-Hardware Configuration\System job folder on the target server. This job disables the embedded array controller and places the HBA controller first in the boot order. |
|
| 3. |
Execute the appropriate operating system installation job from the Server Deployment Toolbox. |
