Is anybody here having problems with Tape Library control through Veeam lately? I have jobs that have run for years and that even survived the V12 update a couple of weeks ago, but have now started throwing a fit every time a tape needs to be loaded/unloaded/inventoried etc. Every error is a variation of the “Failed to call RPC function” message, but with different specifics: LoadMediumByScsi, GetElementsStatusesByScsi etc. This only started on Friday, and is puzzling because it only affects our Dell ML3 (LTO6/LTO8) interchanger, but not the Dell TL2000 (LTO6).
I have tried the usual update of Firmware (Drives and Libraries, SCSI Controllers etc) to no avail. Removing and recreating the Library made little difference either (it loaded a tape ONCE then returned to the errors). Rebooted the Backup Server AND the Library.
Has anyone dealt with this successfully or am I looking at new incident?
