network tranfer rate is very low (about 1-2 MB/s).
Is there method to improve peformance of TSM server ?

Nghiatd,
Have your settings before during backup:-
High Migration Threshold : 80 %
Low Migration Threshold : 25 %.
Later , after backups are complete :-
High Migration Threshold : 0 %
Low Migration Threshold : 0 %.
to allow migration to tape to take place.

Your disk pool is way too small.
It should be large enough to hold one night's backups If you can't do
that, set your hi mig

So the data was migrating from diskpool to tape?
Is it an offline tape that the error relates to?
Can you check your actlog for that time and see if it mentions looking
for a specific tape at that time, then see
to cope with the i/o demands made on it during the backup/migration.
Can you see how far into the backup job these errors are occurrring, how
much data has been backed up to the 20Gb disk when these errors occur.
Is it occcurring around the point where the disk reaches 80% and starts
migrating?

Maybe, but 20% of your 18gb pool is not a lot spare, and I do not think
you will get a continuous migration process anyway. It will reach zero and
then go all the way back to
