Sharing Access to a REO 9000
Between Multiple Systems
The ShareDevice feature lets you share a single disk (physical or virtual)
with more than one initiator. You can use this feature with any
combination of iSCSI or FC initiator connections. However, only one
initiator can access a single disk (physical or virtual) at a time.
Note:
The ShareDevice feature is currently only available on Windows-
based operating systems and is not supported for tape emulation. It
also requires that the size of the device being shared is 400 GB or
smaller.
For Windows-based initiators, the product includes a set of scripts that
helps you automate the process of sharing the disks.
Ovlndstart.exe. You can insert this file into the pre-processing script
of the backup application to suspend operation of the backup job until
the REO Appliance is ready (not in use by another server). If your pre-
processing utilizes a script or batch file, make ovlndstart.exe the first
executable line in the file.
Ovlndstop.exe. You can insert this file into the post-processing script
of the backup application to flush all data from cache and then
relinquish control of the REO Appliance. If your post-processing
utilizes a script or batch file, make ovlndstop.exe the first executable
line in the file.
Important:
If you do not use the scripts, you might experience errors (for
example, “Disk not ready” or “Backup device not ready”) when an
initiator attempts to access a disk that is currently being controlled by
another initiator.
