To perform some tasks, you can run ServeRAID Manager as an installed program.
However, to perform an initial RAID configuration on the server, you must run
ServeRAID Manager in Startable CD mode, as described in the instructions in this
section. If you install a different type of RAID adapter in the server, use the
configuration method described in the instructions that come with that adapter to
view or change SCSI settings for attached devices.
For additional information about RAID technology, see the ServeRAID
documentation on the IBM ServeRAID Support CD. Additional information about
ServeRAID Manager is also available from the Help menu. For information about a
specific object in the ServeRAID Manager tree, select the object and click Actions

Configuring the controller
By running ServeRAID Manager in Startable CD mode, you can configure the
controller before you install the operating system. The information in this section
assumes that you are running ServeRAID Manager in Startable CD mode.
To run ServeRAID Manager in Startable CD mode, turn on the server; then, insert
the CD into the CD-ROM drive. If ServeRAID Manager detects an unconfigured
controller and ready drives, the Configuration wizard starts.
In the Configuration wizard, you can select express configuration or custom
configuration. Express configuration automatically configures the controller by
grouping the first two physical drives in the ServeRAID Manager tree into an array
and creating a RAID level-1 logical drive. If you select custom configuration, you
can select the two physical drives that you want to group into an array and create a
hot-spare drive.

configuration, click Modify arrays.
5. Click Apply; when you are asked whether you want to apply the new
configuration, click Yes. The configuration is saved in the controller and in the
physical drives.
6. Exit from ServeRAID Manager and remove the CD from the CD-ROM drive.
7. Restart the server.
