This chapter contains information and procedures for replacing an LSI host bus adapter.
The following topics are covered in this chapter:
To Replace the LSI Host Bus Adapter on an x64 Server Blade Running Linux or Windows
To Replace the LSI Host Bus Adapter on Any Server Blade Running the Solaris OS
To Replace an Adaptec Host Bus Adapter
If an LSI host bus adapter fails, you must replace it. In the case of the Sun Blade X6220 and T6300 server blades, the host bus adapter is embedded in the server blade so you must replace the entire blade. For other server blades that use a Sun Blade RAID 0/1 Expansion Module (REM), you need to replace the REM.
Note - The procedures below are equally valid whether you are replacing a REM or a server blade with an embedded adapter. |
To Replace the LSI Host Bus Adapter on an x64 Server Blade Running Linux or Windows |
Remove the server blade that contains the damaged host bus adapter.
Replace the host bus adapter (or the entire blade for X6220 servers) and reinsert the server blade.
(Preferred method in all cases) Boot from an external source. Use a bootable thumb drive or a network boot.
If the OS is installed on the server blade (on a single disk in the server blade or in a RAID volume where at least one of the member disks is in the server blade), you can boot from the server’s boot drive. If the boot drive is a RAID volume, during the BIOS boot process you must activate the RAID volume using the LSI RAID configuration utility (see Activating LSI RAID Volumes).
During the BIOS boot process, enter the LSI RAID configuration utility and activate all foreign RAID volumes. (see Activating LSI RAID Volumes).
To Replace the LSI Host Bus Adapter on Any Server Blade Running the Solaris OS |
Remove the server blade that contains the damaged host bus adapter.
Make sure that there is a SAS-NEM in slot NEM 0 and that it is functioning properly (the Fault LED is off).
Remove the SAS-NEM in slot NEM 1, if there is one.
This step is required to make RAID volumes return with the same target ID.
Note - If you have a plain NEM, without SAS capability, in slot NEM 1 you can leave it there. |
Caution - Unplugging the SAS-NEM causes the loss of all secondary network connections and the secondary paths to SAS disks. |
Replace the host bus adapter (or the entire blade for X6220 and T6300 servers) and reinsert the server blade.
Boot from an external source. Use a bootable thumb drive (x64 only) or a net boot.
If the OS is installed on the server blade (on a single disk in the server blade or in a RAID volume where at least one of the member disks is in the server blade), you can boot from the server’s boot drive. If the boot drive is a RAID volume, during the BIOS boot process you must activate the RAID volume using the LSI RAID configuration utility (see Activating LSI RAID Volumes).
Run lsiutil in interactive mode (see To Restore a Snapshot of Your Host Bus Adapter Persistent Mappings). Type 1 and press Enter to open the main menu.
Type 15 on the main lsiutil menu, "Change persistent mappings," and press Enter.
Type 8, "Load persistent mappings from a file," and press Enter.
Reboot the server blade with its own OS.
Rebooting the blade causes it to use the persistent mapping information.
Activate all RAID volumes (see Activating LSI RAID Volumes).
At this point, the blade has been replaced, and all drives and RAID volumes have been configured correctly, thus the blade will be able to boot the OS.
The procedure outlined for LSI host bus adapters is not needed for Adaptec host bus adapters.
