Hello everyone!

Small update on this issue:
Our server has four 146GB disks as pairwise RAID 1 and one of these is
affected by the bug mentioned in the HP support page.
As quick fix i moved our database to the the other raid device built of
unaffected disks. Till now i don't got any new database corruption, so i
think the one disk with the firmware bug is the cause of our problems. Since
only the database does a lot of I/O onto the disks, this will help us for
the next days till we can upgrade or replace the bugged disk.
Thank you all for your hints and suggestions!
