2.7. Configuring SCSI IDs

SCSI IDs are used to identify SCSI devices on a SCSI bus. Since cluster configuration of shared storage requires 2 hosts connect to the same SCSI bus, the host adapter of each cluster must be different. It is required to configure the host adapter SCSI ID to the highest priority. Wide SCSI priority order as 7,6,5,4,3,2,1,0,15,14,13,12,11,10,9.8 and normal SCSI is 7,6,5,4,3,2,1,0 . You should configure the host adapters to 7 or 6 to ensure the host adapters get the highest priority.
