About reserving or releasing shared devices
The Shared Storage Option does not load firmware in SAN devices or communicate with hub or switch APIs. The Shared Storage Option can communicate with hub or switch APIs if you use the NetBackup shared_drive_notify script.
NetBackup runs the shared_drive_notify script when a shared drive is reserved or released.
The script requires the following parameters:
The name of the shared drive.
The name of the current scan host.
The operation, which is one of the following:
RESERVED
The host on which the script is executed needs SCSI access to the drive until it's released.
ASSIGNED
Informational only. It does not change the fact that the host that reserved the drive needs SCSI access.
RELEASED
Only the scan host needs SCSI access to the drive.
SCANHOST
The host that executes the script has become the scan host. A host should not become a scan host while the drive is RESERVED.
The scan host may change between a RESERVED operation and a RELEASED operation.
The shared_drive_notify script resides in the following directory:
On Windows: install_path\Volmgr\bin
On UNIX/Linux: /usr/openv/volmgr/bin/shared_drive_notify
Note:
The script must be executable by the root user.
The script exits with status 0 upon successful completion.
