Larry,
I recently performed this conversion on all of our TSM servers.
To simplify the process, I allocated the new container pool directories on the
same mountpoints and volume groups that held the FILE class data. That way, as
your file volumes empty into the container class pool, you shouldn't need more
than 25% free space to keep things running smoothly.
The convert stgpool process ran relatively quickly, I converted 250TB FILE data
to container in a few weeks.
For TSMB, I'd delete the storage pool with devclass file and create a new
container class pool to take it's place. Then set up storage pool replication
to seed TSMB with TSMA data as the conversion process moves through your data.
The convert process can (and should) be scheduled to run during quiet periods
for a set duration. We ran ours for 6 hours a day.
Let me know how you make out, but you should have no issues. It ran smoothly
on all of our servers, from the smallest instance with ~10TB to our primary
server with ~250TB.
Regards,

Subject: [ADSM-L] Conversion from File to Storage Container on Linux
Background - Earlier this year we moved TSM server from z/OS to Linuxx86_64
server and just then upgraded 2 TSM Servers to 7.1.7 from 7.1.1, each with
9TB of storage divided up across 6 mount points with the storage pool allocated
as a device class=FILE. Each systems sequential FILE pool is comprised of 174
- 50GB volumes. Currently the primary server TSMA has 3.2TB of used space, with
nothing yet on TSMB. Our intention was to have TSMA be the primary backup
server, and TSMB be the offsite server, using Node Replication to sync the
servers daily.
Deduplication is not active at this point, but based on my IBM videos and
documentation it should be turned on with storage containers.
Looking for some assistance. Has anyone converted from using a FILE dev class
configuration to Storage Containers?
All disk drive space has been allocated. Should I begin removing volumes to
free up space so that I can create an LVM for the storage pool container
directory? Then slowly move the currently allocated node backup data on the
volumes to the storage containers?
Any assistance would be greatly appreciated.
Thank you,
