About SCSI reserve limitations
SCSI persistent reserve and SPC-2 reserve do not apply to NDMP drives.
Third-party copy configurations must be configured correctly.
To retain reservation of a tape device during a third-party copy backup, configure the NetBackup mover.conf file.
Do not use SCSI persistent reserve on the drive paths that are used for third-party copy backups.
See the NetBackup Snapshot Client Administrator's Guide, available at the following URL:
With SPC-2 SCSI reserve, devices may remain reserved after a failover in cluster environments or multi-path environments with failover capability.
You cannot use SPC-2 SCSI reserve if the following factors are true: The failover does not break the device reservations and those devices that were in use during the failover must be available without manual intervention. Use SCSI persistent reserve.
If the drive path changes, the backup jobs and the restore jobs fail.
Therefore, jobs fail in cluster environments or any multi-path environments that share paths dynamically. If you cannot disable dynamic path sharing, you cannot use SPC-2 SCSI reserve or SCSI persistent reserve in NetBackup.
