About configuring SCSI reserve
The SCSI reserve protection setting configures tape drive access protection for all tape drives from the media server on which the setting is configured. You can configure the protection for each media server and override the global setting for any drive path.
To configure SCSI reserve protection on a media server: use the NetBackup Administration Console to set the media server host property on the Media tab.
To override the media server protection setting: use the NetBackup Administration Console to set the drive path property when you add a drive or change a drive's properties.
