Check the library settings   if the barcode length is default change it to
extended.
check out all tapes first and check in again afterwards

Hello,
there is a known AIX TCP/IP problem that was recently
discovered with AIX 5.1 64 bit. It is known as IY36925.
It may cause severe performance degradation during
TSM backups. At this time, you will have to call in for
support to get an e-fix as the ptf is not yet available.
Regards,

Did you go to 64 bit mode when you went to 5.1.1.6?  We have some
clients that start out backing up at a good rate and then shift into a
mode where they are running very very slow.  We now think this might be
a 64 bit mode server problem.

We were running tsm 4.2.2.4 on an S7A AIX server.  We were putting
through
approx 1.7 TB nightly with approx 85%
going to disk storagepool and the remaining going direct to tape.  We
were
also testing Lan-free with Gresham EDT-Distributape and STK acsls/9840
tape
drives and we were consistently on an UDB api backup receiving 15 MB/s

one month ago we upgraded all server and storageagents to tsm 5.1.1.6
level
and since then we have seen performance drop.  We are having trouble
getting
through the 1.7 TB nightly.  The same lan-free tests are only getting
us
around 10 MB/s.

We will be upgrading to a bigger and more powerful aix server this
weekend
in hopes that the performance drop is related to our S7a server
reaching the
end of its life span but I know when we upgraded from tsm 3.7 to 4.2 we
saw
an increase in server performance, I'm worried that the upgrade from
4.2 to
5.1 has gone in reverse.

Has anybody sees anything remotely similar after an upgrade to tsm
5.1.1.6
???

thanks
