Hi Mike,

What you want to do depends on how much data you have in the 3590 pools.
Most of what I'm going to say (type, actually) is the same.

Mark your Backuptapepool to readonly. Update your Backuppool pool to point
to Backup-DLT-tape as its next storage pool. Issues backup stg commands to
go from Backup-DLT-tape to Copy-DLT-tape. Keep this up for a while (days,
weeks, months, depending on the amount of data in the 3590 storage pools)
and let normal reclamation continue on the 3590 pools.

Once the 3590 pools are down to a workable level, perform the following
steps:
move data <volume in Backuptapepool> stg=Backup-DLT-tape
(repeat this for each volume in Backuptapepool)
backup stg Backup-DLT-tape Copy-DLT-tape
delete the Copytape storage pool
delete the Backuptapepool storage pool

You can now get rid of the 3590s.

I'm currious. Why are you getting rid of the 3590s? How many do you have?
Can I have them?

Subject:  Moving data from 3490 to DLT




     I need advice with the best way to move data that is currently on 3490
     cartridges to DLT. We are currently setup as:

     Backuppool     primary disk pool         (SSA disks)
     Backuptape     Primary onsite tape pool  (3490 cartridges)
     Copytape       Copy offsite tape pool    (3490 cartridges)

     I defined :

     Backup-DLT-tape primary onsite tape pool (DLT)
     Copy-DLT-tape   copy offsite tape pool   (DLT)

     I was going to update Backuptape to have the migration stgpool be
     Backup-DLT-tape and then set migration down to 0% for high and low.
     Once that is done then issue a "backup stgpool Backup-DLT-tape
     Copy-DLT-tape". Once this is complete I believe I should be able to
     delete the Backuptape and Copytape stgpools and be using just the
     Backup-DLT-tape and Copy-DLT-tape.

     Is this correct and the best way to do this ?
     Or should I update Backuptape for the reclaim stgpool to be
     Backup-DLT-tape and then set reclaim to be at 0%. Followed once
     completed by the "backup stgpool Backup-DLT-tape Copy-DLT-tape"

     I am looking for the easiest way to move all the data and also not
     loose any of it.

     Thanks for any suggestion or info from all in advance.
