I'm weeding my collocgroups, and I decided my management script is
getting smooth enough that I'd consider exposing it for you-all to
take and beat upon if you desire. Throw tomatoes, kibitz, fix my
bustedness, whatever. :)

At least when the source pool is of type DISK, I'd guess
that files will still be ordered by filespace

two migration processes in parallel). TSM Server 5.5.2.1, btw.

So, I'm working on tools (in 'R', my fvorite visualization
environment) to help me understand the impact of a new
collocation-group calculation tool. I'm reaching for some concise
visual idiom which will help me see trouble spots.
What I've arrived at so far is a column for each volume, with

There were just the two tape pools mentioned in my original posting.
Copy pool volumes were sent to an offsite vault. Primary pool
volumes remained onsite.
I believe what TSM does is order the primary mounts by which

data from a different node than the preceeding input tape.
As a result, an input tape mount almost always triggered an output
tape mount.
We just upgraded to TSM 5.3 and are considering the use of

much more flexible than collocation groups. Perhaps he wasn't quite as
crazy as we thought at the time.
Properly deployed, TSM policy should let you do what you really want -

I'm a little confused as to how data is migrated to tape with collocation

tapes show a bit more (~235GB), as if
it did take some compression into account. That shouldn't be right
either though, as I know my data is more compressible than 17%.

Hi David!
Collocation groups are planned to be implemented in 6.1 which is scheduled
for 1st. quarter 2004. I heard rumors about another release (5.3?) in
between, but I haven't seen any details about that release...
Insert usual disclaimer statement here... ;-)
Kindest regards,

Is the collocation groups feature in TSM 5.2.0 or is it further out? If
further out, any word on how far out?

I know it isn't in 5.2.0. I don't know when it will be delivered.
