Unwriteable Cache Data

Danila_2 — Thu, 07 Apr 2011 17:00:33 GMT

After a hot shutdown of one of the disc, i have seen a message in the logs of a P2000 that says: "Unwriteable cache data exists for a volume. (Volume SN******). It comprises 1% of cache space."
After some time (several hours), this message disappears. Where did the data from the cache, and how the cache with the data?

If you are afraid for data integrity, why not run a file check on the file system?

Also I don't understand your terminology.

Hot shutdown of one disc?
-- Did you replace a disk?

I just pulled one drive.
Why unwritable cache data were initially in the cache, and then to have disappeared???

Maybe the controller wanted to write some data to that disk you pulled. Then after rebuild it could write it?
