IBM Partner Pavilion DS4100 manual Installing and replacing components

Go to “Manually upgrading the firmware for the DS4100 single-controller storage server.”

28.For the DS4100 base storage server: See the DS4000 Storage Manager client online help for instructions on bringing the controller online. The RAID controller replacement procedure for the DS4100 base storage server is completed.

29.For the DS4100 single-controller storage server:

Because the replacement RAID controller has a different WWNN that the original RAID controller, you must perform the following tasks in order to bring the DS4100 single-controller storage server to running (optimal) state after you replace the RAID controller.

v Reboot the host server that has mapped logical drives from the DS4100 single-controller storage server.

Rebooting the host server enables the multipath fail-over to recognize the logical drives under the new WWNN. In addition, if your multipath driver uses the WWNN of the controller as part of the LUN identification, you may have to reconfigure the LUN fail-over/failback path information.

vUse DS4000 Storage Manager to rediscover the new RAID controller.

To rediscover the new RAID controller, remove the existing DS4100 single-controller storage server entry in the management domain of the DS4000 Storage Manager client Enterprise Management Window (EMW), and then add the DS4100 single-controller storage server back into the management domain using the in-band or out-of-band management method. See step 6 on page 104.

vRe-enable the premium feature keys.

After you replace the RAID controller in a DS4100 single-controller storage server, all of the enabled premium feature keys are displayed as being out-of-compliance. Use the existing key files to re-enable the premium feature keys.

vIf you create zones using the WWNN, update your zoning definitions with the new WWNN for the replacement RAID controller.

If you are able to to make a management connection with DS4000 Storage Manager to the replacement RAID controller, then the RAID controller replacement procedure for the DS4100 single-controller storage server is complete.

If none of these actions enables you to make a management connection with DS4000 Storage Manager to the replacement RAID controller, then call IBM support for help.

Manually upgrading the firmware for the DS4100 single-controller storage server

You will need the most recent printout of your storage subsystem profile to perform this procedure. If you do not have a printout available, contact IBM technical support to determine the controller firmware and NVSRAM version numbers recorded in your storage subsystem profile.

Attention: This procedure is not self-contained. Perform this procedure only if directed to do so in step 27 on page 101. At the end of this procedure, continue with step 29 in the RAID controller replacement procedure.

Be sure that the BOOTP server configuration includes the MAC address you recorded for the new controller. Refer to step 17 on page 100.
