Correlating tape drives and device files on UNIX hosts
If your tape drives do not support device serialization, you may have to determine which device file or SCSI address matches the physical drive. You also may have to do so if you add the tape drives manually.
Correlate device files to physical drives when you create the device files for each drive.
To correlate tape drives and device files on UNIX
- Determine the physical location of each drive within the robotic library. The location usually is shown on the connectors to the drives or in the vendor's documentation.
- Physically connect the drives to SCSI adapters in the host.
- Record the adapter and SCSI addresses to which you connected each drive.
- Create device files for each drive by using the SCSI addresses of the drives and adapters.
Add the device file by using the notes from a previous step to complete the correlation between device files and physical drive location.
- Configure the robot in NetBackup and then add the drives.
When you add the drives, verify that you assign the correct drive address (for example, robot drive number) to each device path.
Optionally, use the appropriate NetBackup robotic test utility to verify the configuration.
To verify the device correlation on UNIX
- Stop the NetBackup device daemon (ltid).
- Start ltid, which starts the Automatic Volume Recognition daemon (avrd). Stop and restart ltid to ensure that the current device configuration is activated.
If robotic control is not local to this host, also start the remote robotic control daemon.
- Use the robotic test utility to mount a tape on a drive.
- Use the Device Monitor UI to verify that the tape was mounted on the correct robot drive.
