Hi I am backing up a large file server using SP and with the 'dsmISI mags' product to improve the sessions and speed, the backup runs great but I am having an issue migrating the data from the diskpool to tapepool (4 Gb FC) in a reasonable amount of time. How can i get multiple process to migrate the data in parallel?
For example, my diskpool is 2.5 TB (i can't increase it further) the fileserver is about 30 TB. I have one single 'node name' for the entire fileserver. I have no problem after the initial full backup because everything else is incremental but i am trying to backup a new share that is approx 12 TB. What I am doing is backing it up and filling the diskpool in a matter of an hour or two over 10Gb but then I have to wait the entire day for the migration to empty the diskpool to tape before I can backup another 2.5 TB and start the cycle again until i finish backing the entire share.
it seems that there is only 1 migration process is it because it is only 1 node? Please let me know if anyone has ideas. the tape drive is 4 Gb fiber channel but i honestly dont see it pushing the data as fast as i expect when i look at it with nmon (this is an AIX system).
Thank you i appreciate any advice
