To use SCSI persistent reserve or SPC-2 SCSI reserve, the following requirements must be met:

• There must be pass through driver access to all shared drives.

  The pass through driver must be installed and all required paths must be created.

  Information about how to configure and use the pass through driver for UNIX operating systems is available.

• You must configure the operating systems on the NetBackup media servers so they let NetBackup control SCSI persistent reserve or SPC-2 SCSI reserve.

• Depending on the tape drives, you may have to disable the operating system's use of SPC-2 SCSI reserve. Solaris may require such a change.
