The battery-backup cache device failed -and volume shadow copy - server hang

Hello,

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

Did you check your raid controller? You have to put the last drivers and firmware, if not open a hardware issue with ibm and change raid controller. When you change you have to save the configuration from disk to nvram, never in the reverse or you will lost all data.
