I have done it both ways, the biggest difference I found were the
commands used.  Both took about the same amount of time.
I would suggest doing the move when expiration is not running and when
there are not many backups running. And always make a backup first, but
you knew that...

Agreed. That's the way I did a similar migration recently. No downtime
that way.

Hi!

I just went through this process myself but I normally just make the new
volume a copy of the original and once the synchronization process is
complete, then I delete the original volume.

Hi there all,

TSM 5.2.7 on AIX 5.3.3 - question is about deleting a db vol with the
intent to "move" it.  As one can see from the output of the q dbv
command we have 2 db vols.  The first is on a local disk array and the
second on enterprise storage disk.  The goal is to get the DB off the
local disk and onto the enterprise storage disk.

ANS8000I Server command: 'q dbv f=d'

Volume Name (Copy 1): /adsmserv/db/dbvol01.dsm Copy Status: Sync'd
Volume Name (Copy 2): 
Copy Status: Undefined
Volume Name (Copy 3): 
Copy Status: Undefined
Available Space (MB): 50,000
Allocated Space (MB): 50,000
Free Space (MB): 0

Volume Name (Copy 1): /adsmserv/db2/db2.dsm Copy Status: Sync'd Volume
Name (Copy 2): 
Copy Status: Undefined
Volume Name (Copy 3): 
Copy Status: Undefined
Available Space (MB): 81,000
Allocated Space (MB): 10,000
Free Space (MB): 71,000

If we run the command "delete dbv /adsmserv/db/dbvol01.dsm", TSM is
smart enough to move the database contents out of
/adsmserv/db/dbvol01.dsm and into /adsmserv/db2/db2.dsm.  Is that
correct?  This delete/mov occurs during the background without
interrupting other TSM processes and sessions?

We would also like to delete/move the log vol in the near future.   This
move isn't from local to enterprise storage, just from one local array
to another.  We have not defined the new log volume or extended the
current log volume.  Assuming this work has been done... can we (again)
simply "delete logv" on the log volume we want to "move" from?

ANS8000I Server command: 'q logv f=d'

Volume Name (Copy 1): /adsmserv/log/logvol01.dsm Copy Status: Sync'd
Volume Name (Copy 2): 
Copy Status: Undefined
Volume Name (Copy 3): 
Copy Status: Undefined
Available Space (MB): 10,000
Allocated Space (MB): 10,000
Free Space (MB): 0

Thanks so much!

Scott
