The battery-backup cache device failed -and volume shadow copy - server hang
I have an IBM x345 series server RAID 5 - with RAID5i controller
I moved server other day - seemed to come up ok - however a day later i got error The battery-backup cache device battery failed - I understand its gone into write-through mode now - with performance hit. BUT - it now seems to hang at least once per day - and I now need to reboot to fix. - this is our file sever which basically pulls down our entire LAN.
I noticed in event logs that there is just before the hang the VSS - vol shad copy servers doing its thing and stopping starting etc and creating snap shots - Ive decided to stop this process and in fact disabled the vss service - (all seems ok - but im getting some DCOM errors in log - that dont effect anyone) i did this today - no hangs as yet. I m asking if it is safe to disable the VSS -? Also I dont quite see why the if the battery cache has failed on the RAID card it would grind the server to halt - unless high write I guess. Im getting new battery sent through for card - but just wanted advice on best course of action and explanation of what to do to rectify if possible - Would the vss shadow copies be causing the crash? - thanks
