Good morning,
we have two BE 12.5 servers connected to a Overland Neo8000 library with 2 LTO4 drives and a Overland Reo9100 VTL via FC SAN.
SSO and Library Expansion Option are installed on both servers.
One Server is Central Admin Server, the other Managed Media Server.
We make backups to the VTL and then duplicate the backup sets to the Neo8000.
During the duplicate jobs the drive(s) of the Neo8000 frequently go offline.
Sometimes it's one drive, sometimes both, and sometimes it's the whole library.
Furthermore sometimes a drive is only shown as offline on one backup server, sometimes on both, ...
The jobs hang with "Ready, no idle devices..." or are "missed" or "failed"
When I take the drives online again, I can start a job, sometimes two, and then sometime it get's offline again.
Restarting the library doesn't make any difference.
Medium changers are configured as "Unknown Medium Changer", BE drivers are installed for all tape devices.
BE 12.5 is patched with most current hotfixes, we had the same problem with all patch levels before.
OS platform is Windows Server 2003 SP2 Standard Edition with all the latest security patches installed.
We also had a similar problem with the VTL, but that was fixed after updating Windows and BE some time ago.
Any suggestions?
Kind regards,
Stefan
