Hello all,

I applied OCE1 microcode to 2 3583 drives recently, and i think
performance is suffering now!  Backup seems fine, but tape-to-tape
operations is taking forever...  perhaps restore is suffering as well, i
have not tried any large restores.

I'm seeing the same behavior Rejean describes below.  A few files will be
copied, then a pause for 1-2 minutes, then a few more files.  In backing
up a primary storage pool to copy storage pool, it only backed up 60 gigs
in 9 hours. Does this seem too slow? (it does to me...)

I noticed at ftp://service.boulder.ibm.com/storage/358x new microcode
12U7.fmr was released on 5/7.  Can anyone confirm if this will fix my
problem? Also...what is the 12U7.ro file?

--Ray
