Hi Andy and all,
Recently we did try to export some data from onsite production server to
offsite server. We did a media export rather than server to server export
due to network bandwidth and to save TSM resources on the onsite
production server . Well, mine is just around 2TB and all goes into
tape(s).
On the offsite, I'll make sure there's a storage pool with enough tapes. I
did a preview before importing it to estimate the quantity of tapes
needed.
Then import the node definition and lastly import the data into the
storage pool.
I'm on my way bring up the database (SAP R3 for Oracle). However I'm
facing difficulties in doing so. The log file for TDP restore on the file
level system no longer exist and therefore brtools can't be used to do the
restore. We are looking for ways to bring up database.
Anyone can share and help on this problem of mine?
Thanks and Warmest Regards,

Re: [ADSM-L] Export Node
Yes we here at Duke have mover over 14 TBs of data with this method
And we were able to move about 1 TB per day with our environment.
From: TSM Server: AIX 5.3 IBM, 7026-H80 4 GB memory 450 MHz CPU
To: TSM Server: AIX 5.3 (P630) IBM, 7028-6C4 4 GB memory, 1.2 GHz CPU
Have to make sure that your tape drives our available for the extra work.

Subject: Export Node
I need to export some nodes from one TSM server to another to balance
the load.
I tested the command 'export node1 filedata=all toserver=serverb
mergfilespaces=yes' and got a data rate of about 16GB an hour. The 2nd
run of the exact same command finished in 1/4 of the first run time and
moved no data. (no changes to the data between runs) This indicates
that there is a time savings for the incremental passes should the
process end before completion.
Has anyone used this method to move TBs of data between TSM servers
while the nodes are active? I cannot stop backing up the node for the
week it will take to move the data.
Are there any other faster ways to move the data?
