Resetting a drive
Resetting a drive changes the state of the drive.
Usually you reset a drive when its state is unknown, which occurs if an application other than NetBackup uses the drive. When you reset the drive, it returns to a known state before use with NetBackup. If a SCSI reservation exists on the drive, a reset operation from the host that owns the reservation can help the SCSI reservation.
If the drive is in use by NetBackup, the reset action fails. If the drive is not in use by NetBackup, NetBackup tries to unload the drive and set its run-time attributes to default values.
Note that a drive reset does not perform any SCSI bus or SCSI device resets.
To reset a drive
- Open the NetBackup web UI.
- On the left, select Storage > Tape storage. Select the Device monitor tab.
- Locate the drive that you want to reset. Then select Actions > Reset drive.
If the drive is in use by NetBackup and cannot be reset, restart the NetBackup Job Manager (nbjm) to free up the drive.
- Determine which job controls the drive (that is, which job writes to or reads from the drive).
On the left, select Activity monitor. Then on the Jobs tab, cancel the job.
- In the Activity monitor, restart the NetBackup Job Manager, which cancels all NetBackup jobs in progress.
