You can also determine the proper settings for the controller name and partner
name of the controller being replaced by reading the settings from the cluster
partner system.
v
Stripe-unit size
The stripe-unit size must be the same on both controllers in a high-availability
cluster.
v
Unattended mode setting
This setting is configured automatically as Enabled when a controller is set up for
clustering.
If the ServeRAID controller you are replacing is functional, you can obtain the
above configuration information by starting your server with the IBM ServeRAID
Support CD in the CD-ROM drive and using the ServeRAID Manager program. For
additional information, refer to the ServeRAID Manager online help.
Note: The configuration information is also available in the printable configuration
file you might have saved when configuring the ServeRAID controllers for
clustering.
If the ServeRAID controller is not functional, you will need to refer to a record of the
settings that was made when the controller was previously configured. If you do not
have a record of the configuration information, refer to “Obtaining the current
configuration information” for information that might help you to assign the proper
values.
Obtaining the current configuration information
To obtain the SCSI initiator IDs, controller name, partner name, and stripe-unit size
from the corresponding cluster partner controller, do the following:
1. Start the cluster partner system with the IBM ServeRAID Support CD in the
CD-ROM drive. The ServeRAID Manager program starts.
2. In the Main Tree, click the cluster partner controller.
3. Click on the tool bar. The Configure controller for clustering window
opens.
