Thanks paul,
Yes, We are doing Server-to-tape exports. I did notice a couple times long
input tape mounts on the destination TSM SERVER one was around 6,000 seconds
another around 14,000 seconds and another 17,000 seconds.
Also, I noticed the one clients SYSTEMSTATE number of files is 815,709? This
export is going take forever

Subject: Re: EXPORTING clients
We have found that moving the data to a serial disk pool first, before
exporting the data (server-to-server), can really speed things up. In fact, I
am suspicious that TSM may not be optimizing tape mounts for node exports, or
at least under some circumstances. We observed very iffy behavior in this
respect but never had time to investigate it enough to open an ETR on it.
Check your actlog to see if you are seeing a lot of tape mount activity
associated with the export process.
If you are doing server-to-tape export, the above recommendation may not apply.
