Are others seeing WIDELY varying times for migrations ?
I'm AIX 4.1, ADSM 2.1.0.8 (will be 0.9 today) comming off SSA dasd and
going to 3590 drives. There are a few things I'm in the process of
enhancing, such as adding another FWDiff SCSI card to put each tape
drive on its own and I just max'ed out my MOVEBATCHSIZE at 250 (up
from the 40 it was at...) I've seen a couple of things that I need to
try to correct such as 46,657 files @ 38.5 GB taking 28 hours to
migrate while 55,584 files @ 31.8 GB took 10 hours... each of these
packed down onto 1-10GB tape and were each a process running against
the same storage pool at the same time... other processes running
against the same storage pool at the same time looked like 3hr40min to
move 3,295 files @ 51GB, 5hrs to move 2,947 files @ 60 GB, 9 hrs to
move 51GB (I don't have the file count on this one yet)
Would others agree that a 59H or 591 used as an ADSM server should be
limited to under 200 to 250 GB backup activity per 24 hour period...
It seems that everytime I get in this range, all the daily activities
start to run into the next 24 hours...
I'm looking forward to U'all's comments...

later
