Appendix B, Automated Cartridge System (ACS)
Configuring ACS Drives
343
This means that there can be up to three different DLT and three different 1/2-inch
cartridge drive types in the same robot. If you are using alternate drive types, it is
important that the volumes are configured using the same alternate media type. Six drive
types are possible, as follows: DLT, DLT2, DLT3, HCART, HCART2, and HCART3.
Use the same methods to create or identify device files for these drives as for other drives.
If the drives are SCSI and connect to the robot through a shared control unit, you must
specify the logical unit number (lun) for each drive, as they share the same SCSI ID.
Refer to the system documentation for your platform and operating system for details on
configuring drives and logical unit numbers. The NetBackup Media Manager device
configuration guide also has information on configuring device files.
Although device file configuration is essentially the same as for other robot-controlled
drives, you must include the following additional information when defining the drives
in Media Manager as robotic.
Also see “Configuring Storage Devices” on page 17 for information on configuring ACS
drives.
The following figure shows the location of this information in a typical ACS robot:
ACS Drive Coordinate Description
ACS number The index, in ACS library software terms, that identifies the robot
that has this drive.
LSM number The Library Storage Module that has this drive.
Panel number The panel where the drive is located.
Drive number The physical number of the drive in ACS library software terms.
