The SCSI initiator IDs for a non-shared SCSI channel are set to 7. For shared
SCSI channels, the initiator IDs must be 7 or 6 and must be different from the
SCSI initiator IDs for the corresponding SCSI channels of the cluster partner
controller. Therefore, if you can obtain the SCSI initiator IDs for the
corresponding cluster partner system, you know the correct SCSI initiator IDs for
this system. For example, if the cluster partner system-shared SCSI initiator IDs
were set to 7, the controller you are replacing would need to have its SCSI
initiator IDs set to 6.
v
Controller and partner name
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. Click Start
→
ServeRAID Manager.
or
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 (
Configure for clustering
) on the tool bar. The Configure
controller for clustering window opens.
