Take a look at SRN 42525 in the adapter user guide. (I'm looking at the
Advanced Serial RAID Adapters User's Guide and Maintenance Information.)

Subject: ssa adapter cache error


I'm not entirely sure what happened here or what's going to
be the least painful remedy but we had an SSA adapter (6230 I
think) that was saying the battery needed to be replaced(
SSA_CACHE_BATTERY). My co-worker got a battery and what I
think is the fast rw/cache that goes with it?
I've replaced batteries before with no problems but this time
it came enclosed in what I think is the 32MB fast write cache.
At any rate, down the server and swap out the battery and
cache since it was easier than unclipping just the battery
but at bootup the VG is now unaccessible due to a wrong_cache error.

hdisk3 F41F43ECA6254CK wrong_cache
127.6GB RAID-5 array

So I can't varyon the vg anymore etc.
Anybody ever see this error before?
Any suggestions? This is a test server so I can just blow
away the array, rebuild and restore if needed.
I wasn't actually working on this but it should now be back
to it's original config with old battery and module.
