Preconfiguration Information
The choice of SCSI target ID numbers is limited. Assuming the maximum number
of targets per channel on the particular controller is MAX_TGT, the SCSI target
IDs on a given channel should range from 0 to (MAX_TGT – 1). See the vendor
documentation for more information.
SCSI target IDs on one channel can be repeated on other channels.
Example 1: The 5-channel models support a maximum of four targets per channel,
that is, MAX_TGT = 4. Therefore, the SCSI target IDs on a given channel should
range from 0 to 3.
Example 2: The 3-channel models support a maximum of seven targets per channel,
that is, MAX_TGT = 7. Therefore, the SCSI target IDs on a given channel should
range from 0 to 6.
Known Problems and Limitations
If a SCSI disk drive is not defined to be part of any physical pack within a system
drive, it is automatically labeled as a standby drive. If any SCSI disk drive within
a system drive fails, data on a standby drive may be lost due to the standby
replacement procedure. This replacement procedure will overwrite the standby
drive if the failed disk drive is configured with any level of redundancy (RAID
levels 1, 5, and 6) and its size is identical to the size of the available standby drive.
