Yes! It does work for TSM 4.x! This is great! Saves us a heck of a lot
of back and forth trips up to our library.

And for Joe Faracchio: I'm also going to look into your method too. The
only question is, at the end of the reclamation, how do you know which
15-30 tapes got reclaimed? Do you just do a "q v
stg=[offsite-backup-copy-name] acc=offsite" and look for 0.0%/Empty?

I assume you can then just checkin these volumes as "scratch" (or do you
have to check them in as private, do a delete, and then check them out
again?).

Now if I can just sync up the home elements and the slot numbers, I'll
be able to change my subject line ;).

Thanks again to everyone for the help!

put the data on a new tape for the off-site copy pool. I'm running TSM

I've had to do this for some time, as I've had DLT tapes (and now LTO)

reclaim at xx% gets ugly when you want to recover a 50% full (and

LTO tape that has 48 GB on it but do not want to reclaim a 50% full (and

Here's what I've got going right now:

Unless something happened over night, that  I have yet to hear about.

"John, you don't need to bring copypool tapes back on site to
reclaim them.
Just do a "move data" on the off-site volume and TSM will
rebuild it from
the original tapes in the library."

This statement would be false:  If you are going to "move data" the
off-site or what ever tape/data you are moving  will have to be in the
library.

If you are going to "Reclaim" , the off-site/copy pool tape
would not need
to be present in the Library.

1. Yet their device support website

(http://www.tivoli.com/support/storage_mgr/devices/all.html) lists the
element matrix for Gator, where slot 1 is element 1, but
TSM actually
sees it as 1 + 29, or 30. And drive 1 is supposed to be 646, but TSM
sees it as 646 + 29, or 675. Again, despite their own matrix,
TSM seems
to have added 29 to the element addresses they list.

2. The reason I do "move data" is to consolidate the data that is
offsite. So, if I have a volume offsite that is
"under-utilized" (let's
say only 22% utilized), then I would want to check that tape
in, and do
a "move data" onto a pool-copy "filling" tape. But it won't
let me do a
"move data" unless the tapes associated with that one are
also in the
library.

3. Yes, as I mentioned, it's most likely a SpectraLogic issue. Just
wanted to see if other folks were having similar issues.

Subject:  TSM annoyances


I have a few annoyances with Tivoli -- not many, as it's a great
product, just a handful.

1) We have TSM 4.1.3 server connected to SpectraLogic Gator/64000.
Despite what Tivoli says on their website, the element
number of Slot 1
in the library is not 1, but 30! This is very annoying!
If I do a "q
libv lib1" and look up a volume's home element, I have to
subtract 29 in
order to really know what slot it's in on the library. Can this be
corrected so that it is what Tivoli's website says it
should be -- i.e.,
element 1 matches slot 1?

2) Is there a simple way to find out which volumes are
associated to any
other? For instance, let's say I have to do a "move data"
on 000115.
Right now, here's what I do:
q content 000115 count=-1 f=d
q content 000115 count=1 f=d
        If either one of these has a segment 1/1, then
everything's
great,
as there is no associated volume. But if either or both
have 1/2 (or
2/2) then I have to issue:
audit v 000115
        And find the associated volume. The catch is, if
there are *two*
associated volumes, you have to check one of them in first
and update
its status, before you can do another audit to find the
other associated
volume.
        Is there any way to find these associated volumes
in one swift
command?!

3) [I think this is more a SpectraLogic issue, but I'll gripe
anyway ;).] When I want to "bulk load" a bunch of tapes
into the Gator
tape library, I have to make sure no tapes are mounted in
the drives.
Otherwise, the bulk load will just blindly put the new
tapes into the
slots of the tapes in the drive. Doesn't TSM "talk" to the
tape library
and tell it the home elements (or slots) of the tapes that
are mounted
in the drives, so that the robotic picker won't put tapes
into those
slots??

Thanks for any advice.
