About configuring ACS drives
An ACS robot supports DLT or 1/2-inch cartridge tape drives. If an ACS robot contains more than one type of DLT or 1/2-inch cartridge tape drive, you can configure an alternate drive type. Therefore, there can be up to three different DLT and three different 1/2-inch cartridge drive types in the same robot. If you use alternate drive types, configure the volumes by using the same alternate media type. Six drive types are possible: DLT, DLT2, DLT3, HCART, HCART2, and HCART3.
Before you configure drives in NetBackup, configure the operating system tape drivers and device files for those drives. For information about how to do so, refer to the operating system documentation. For guidance about the NetBackup requirements, see the information about the host operating system in this guide
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, the drives share the same SCSI ID. Therefore, you must specify the same logical unit number (LUN) for each drive.
When you configure ACS drives as robotic in NetBackup, you must include the ACS drive coordinate information.
The following table shows the ACS drive coordinates.
Table: ACS drive coordinates
ACS drive coordinate | Description |
|---|---|
ACS number | Specifies the index, in ACS library software terms, that identifies the robot that has this drive. |
LSM number | Specifies the Library Storage Module that has this drive. |
Panel number | Specifies the panel where the drive is located. |
Drive number | Specifies the physical number of the drive in ACS library software terms. |
The following figure shows the location of this information in a typical ACS robot.
