About SCSI persistent reserve conflicts

NetBackup uses unique reservation keys. Therefore, NetBackup attempts to resolve conflicts with other NetBackup reservations. If a conflict exists, NetBackup sends SCSI commands to unload the drive. Based on the drive status, NetBackup tries to unload the drive again by using additional information to release or preempt the persistent reservation.

In cluster environments after a failover event, NetBackup on the active cluster node detects the persistent reservation and clears the reservation. NetBackup regains use of the drive without power-cycling the drive.

If NetBackup does not own the persistent reservation, NetBackup reports a pending status in the Device Monitor. The reservation owner must clear the reservation before NetBackup can use the drive. For example, NetBackup does not clear a NetApp persistent reservation.
