11. Connect the expansion enclosure to each of the ServeRAID controllers.
Important
When connecting the cables, you must connect the same channel connectors on both
ServeRAID controllers to the same expansion enclosure. For example, if you connect the
cable from Channel 1 on the first ServeRAID controller to the first expansion enclosure,
then you must connect the cable from Channel 1 on the second ServeRAID controller to the
first expansion enclosure.
12. Remove the IBM ServeRAID Support CD (or the configuration CD that was
included with your server) from the CD-ROM drive; then, turn on the server.
13. Start the ServeRAID Manager that is installed on the server and confirm that
the ServeRAID controllers are in a failover pairing (see Figure 19 on page 68).
Replacing a controller of a failover pair in hot-plug PCI slot
If the failed controller is in a hot-plug slot, refer to the documentation that comes
with the server for instructions for replacing the controller.
Recovering from a power failure during a failover
If a power failure occurs during a failover, it is possible the two controllers in the
active-passive pair might have the following problems:
v
Some logical drives are configured on one controller and some logical drives are
configured on the other controller.
v
A logical drive does not appear on either controller.
To recover from a power failure, do the following:
1. Run ipssend merge for every merge group number configured on the controller
that you want to be active in the pair.
2. Run ipssend unmerge for every merge group number configured on the
controller that you want to be passive in the pair.
3. Shut down and restart the server. Windows NT and Windows 2000 pairs the
controllers again.
Troubleshooting an IBM ServeRAID Cluster Solution
There is the possibility that one of the servers, one of the ServeRAID controllers, or
one of the hard disk drives in a cluster might fail. This chapter presents procedures
you can take to recover from these potential problems. If you still have problems
after following these procedures, contact your IBM service representative for further
information. Also, you can find hints and tips to help you solve problems on the IBM
Support Web site. See “Downloadable files from the World Wide Web” on page 14
for additional information.
