I would create and format the volumes from within TSM. This will speed
things up!

Onderwerp: Dsmfmt on cx600 any thoughts?
Greetings,
We have serious performance issue for dsmfmt command.
We are getting 45MB/sec write speed on AIX4.3.3 box connected to CX600 ATA
RAID5 4+1 disk group.But when we use dsmfmt it gives 9 to 16 MB/sec. Which
is very sluggish to format 16 TB storage for storage pools.
Does anybody have information on how dsmfmt works?
or how to speed up so that it will give better I/O on SAN storage?
Thank you,
