Replacing a ServeRAID controller
Complete the following steps to replace a failed ServeRAID controller in your
high-availability configuration:
1. Shut down the server.
2. Note which SCSI cables are connected to which SCSI channel connectors on
the controller.
3. Note which PCI slot has the controller installed.
4. Remove the failed ServeRAID controller.
For instructions on how to remove and install the ServeRAID controller, see
the installation guide that came with your ServeRAID controller.
5. Install the new ServeRAID controller. Be sure to install the controller in the
same PCI slot from which you removed the failed ServeRAID controller.
Important
v Do not reconnect the SCSI channel cables to the controller at this time.
v You must ensure that you have the same level of ServeRAID BIOS and firmware on both
controllers in the cluster.
The software is available on the IBM Support Web site. See Chapter 16, “Obtaining
ServeRAID updates” on page 141 for additional information.
6. Start the system with the IBM ServeRAID Support CD (version 4.0, or later) in
the CD-ROM drive. The ServeRAID Manager program starts.
7. In the ServeRAID Manager tree, click the new controller.
8. Click Actions → Restore to factory-default settings . The ServeRAID
Manager program initializes the controller configuration.
9. With the new controller still selected in the tree, click ( Configure for
clustering ) on the toolbar. The “Configure controller for clustering” window
opens.
10. Using the settings that were assigned to the previous ServeRAID controller
(that is, the controller you are replacing), complete each of the following fields:
v SCSI initiator IDs
v Controller name
v Partner name
11. Click OK . The new controller stripe-unit size setting defaults to 8 KB. If you
need to change this setting to match the partner controller, go to step 12.
Otherwise, go to step 15 on page 170.
12. In the ServeRAID Manager tree, click the new controller.
