The preparation procedures for preparing both SCSI host adapter products are
provided in the following sections.
Setting SCSI Host Adapter Termination
Adaptec AHA-2944UW Termination Procedures
Termination on the Adaptec AHA-2944UW host adapter is controlled by
software commands via the SCSISelect utility. The default setting is
automatic, which is not supported in a StorageWorks RAID Array 3000
cluster. Using the SCSISelect utility (as described in the Adaptec AHA-
2944UW Installation Guide), change the default settings for both SCSI host
adapters in your cluster as follows:
For Host Adapters in this RAID
UltraSCSI Layout
Set the AHA-2944UW Termination to
Hub-Radiant RAID ON/ON
End-Bus RAID OFF/OFF
NOTE: In SCSI hub configurations (for example, a hub-radiant RAID cluster layout),
termination is internal to the SCSI hub, which necessitates the ON/ON termination setting.
Setting Unique SCSI Host Adapter IDs
A cluster requires that each server has a unique SCSI host adapter ID (target
ID). Set the SCSI ID of one of your host servers to 6 and the other to 7.
Setting SCSI Bus Reset to Disable
Refer to your Adaptec host adapter reference manual and follow the procedure
to set the SCSI Bus Reset option to Disable on both host adapters. (For the
SWXA3-BD, 1 = disable).
