Informational only. It does not change the fact that the host that
reserved the drive needs SCSI access. ASSIGNED
Only the scan host needs SCSI access to the drive. RELEASED
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.
SCANHOST
The script resides in one of the following directories:
Windows:
Install_path \VERITAS\Volmgr\bin
UNIX:
/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.
How to share robotic libraries without using the
Shared Storage Option
You can share robotic tape libraries among multiple NetBackup media servers by
using any of the following methods:
■
Shared library support
NetBackup allows different drives within the same robotic library to be
configured on different media servers. This capability is termed shared library
support. Robot types that support shared library are ACS, TL8, TLD, TLH, TLM.
■
Partitioned libraries
Some robot vendors also let you partition libraries. One partitioned view of
the robotic library includes one set of drives, while the other view has a
different set of drives in the library. Partitions let two robotic control daemons
on different control hosts manage the robotic library — possibly each for a
different NetBackup master and media server environment.
■
Multiple master servers
Use multiple NetBackup master servers that share a common media and device
management domain. This means that the master servers use the same EMM
server.
