Hi Debbie,

If your diskpool is big enoufh, you can try a "move nodedata <nodename> 
from=<tapepool> to=<diskpool>" first, so you can restore from disk. Than you 
know if the problem is in the library or not.

I also know that Netware is not so fast in building big directory structures, 
so you can also win alot with dirmc, than TSM restores the directory stucture 
first, and than the files. If posible you can even use a small diskpool for 
dirmc's only, what you don't migrate to tape, this is also a big winner when 
restoring "slow" FS's as Netware and NTFS.

Regards,
Maurice

  Oops, I meant to include that in the email. The bottom of this doc shows the 
transfer rates..

  What  did the tranfer rate show as?

  1024 x 6.24 = 6389MB (megabyte)

  Network is usually in Megabit, yes?

  6389MB x 8 = 51112 (megabit)

  This doc offers alot of information about improving performance. I'm
  especially interested in this because it took 56 minutes to restore
  6.24G
  of data, from Novell server to Novell server, over a 100MB pipe.

  Our TSM version is 5.1.1 ( I know,,,we need to upgrade)...and the
  client
  version is 5.2.

  In the dsmserv.opt file the MIRRORWRITE DB = SEQUENTIAL. According to
  this
  doc, we'll get better performance is we change MIRRORWRITE DB to
  PARALLEL.
  I thought I would do this then add the DBPAGESHADOW = YES parameter.
  (the
  MIRRORWRITE LOG = PARALLEL)

  My plan is to make small changes to see if there is an impact, positive
  or
  negative. We have 2G of virtual memory, so I changed the bufpoolsize
  from
  262144 to 524288 and thought I'd make the MIRRORWRITE DB change also.

  Has anyone made these changes and seen any performance
  improvements/degredations? Any experiences or advice is welcome.....

  Thanks for any input,
  Debbie
