Setting Tape Drive Parameters
Administrative users can view and modify certain tape drive parameters.
You can set the SCSI ID for a SCSI-attached tape drive and the loop IDs,
topology connection mode, and interface speed for a Fibre-attached tape
drive. You can view but not set parameters for SAS tape drives. A SAS
tape drive’s SAS address is automatically and uniquely generated based
on a unique World Wide Node Name (WWNN) that the drive receives
when it is configured.
If the affected partition is online, it will be taken offline before the
parameters are set, and brought back online after they are set.
Each device on a SCSI bus, including the host bus adapter (HBA) needs to
have a unique SCSI ID. Changing the SCSI ID is necessary when there is a
duplicate ID on a single bus. Typically, the HBA SCSI ID is set to 7. For
example, if two tape drives are connected together on the same bus, each
tape drive must have different SCSI IDs and they must be different from
the HBA SCSI ID.
For SCSI tape drives, a SCSI ID can be set to a value from 0 to 15. The
library assigns the following default SCSI IDs to SCSI tape drives:
• Control module: 1 and 2
• Each expansion module: 3, 4, 5, and 6
Note:
This operation cannot be performed concurrently by multiple
administrative users logged in from different locations. You
can access the screen, but you cannot apply changes while
another administrative user is performing the same operation.
