Caution: The model number is set at the factory and should be changed only
at the direction of an authorized service representative.
SCSI ID Assignment Guidelines
When selecting SCSI ID numbers, each SCSI device on the same bus must have a
unique number from 0 to 15. SCSI devices include the library robotics, the host
bus adapter, and the library tape drives.
If you set up the library with multiple SCSI buses, you can assign the same
number to two or more devices, provided each device is on a different SCSI bus.
Note: Power must be cycled for the new SCSI ID number to become effective.
PTM Configuration
To configure the optional PTM, refer to the HP StorageWorks ESL9000 Series
Pass-Through Mechanism Installation Guide that shipped with the PTM.
