Yep.
In our case, the database backups go off-site with the copypool tapes
and we ship (or hand-carry) all tapes that are off-site from our storage
location (the company hangar) to the D/R hotsite at the time of the
test. So I've usually got two to six 'empty' tapes off-site per the most
recent database backup, but I'll never have off-site tapes NEWER than
the database backup -- unless we can't read the most current database
backup. (And *that* will cause REAL heartburn).

Only thing I would disagree with is the order of your checkins. Maybe
for an actual disaster, but for a D/R test where you have your
copypool tapes shipped to the recovery center, depending on the timing
of the dbbackup you'll be restoring and those tapes, there
could actually be "live" tapes that your restored DB doesn't know about
if they were created and shipped after your restore point.
Those "live" tapes will then be checked in a scratch, possibly
overwritten depending on what you do at D/R. If they need to be used
later, they are now no good.
I always load all my copypool tape in the library and do a checkin
search=yes stat=private. Then if I have any scratch tapes I want
to use, I'll check them in search=bulk. That way I won't accidentially
overwrite good data.
Just my $.02 worth...and that may even be over-priced!

No problem.
Rebuild (from mksysb) your TSM server.
Restore your TSM database (you'll need the current TSM device config
file and volume history file, with the device config file
changed to match the proper rmt names for the tape drives) --
OR -- we have a custo D/R device config file that defines the library as
type manual, not SCSI, with one tape drive and path. We
update the path to match the machine's tape drive definition for the
first LTO drive.
Then we restore the TSM database, specifying the volume number, and
mount the tape manually.
Once TSM is up, delete the paths and re-define them to match the new
environment.
Then 'upd vol * acce=unav whereacce=reado,readw" to mark all the primary
tapes unavailable.
And 'upd vol * acce=reado whereacce=of' to mark all the off-site tapes
read-only.
File the library, if you haven't already done so, and then:
'audit libr <your name> checklabel=barcode'
'checkin libv <your library> search=yes stat=scr checklabel=barcode' to
check in any scratch tapes 'checkin libv <your library>
search=yes stat=pri checklabel=barcode' to check in all the data tapes.
Run the checkins in that order; if you do stat=pri first you won't have
any scratch tapes (we keep 20 initialized tapes off-site as
available scratch tapes to carry us through the first 48 hours of
recovery).
Don't forget to disable or delete your scheduled events until you've got
most of your recovery done -- a lot of your archival data
is going to expire on you fairly quickly if you're recovering from an
older database backup.
We've been doing this for nearly seven years now, with no problems.

Subject: restore directly from copy pool tapes
I'm working on a disaster recovery scenario where our TSM server (AIX)
and tape library (3584)that has 90 LTO tapes in tape pools is
destroyed and several other servers are destroyed. We have approx. 85
copy pool tapes off site.
Our thought is to recreate the TSM server via mksysb, restore the TSM
database, etc. Then get several of our critical other systems
up and restore their data by using the copy pool tapes and then recreate
the tapes in the tape pools in the tape library.
How does one set up the recreated TSM server so that it does not think
that the tape pool tapes are in the tape library ?
How does one restore from copy pool tapes ?
Are we going about this in a realistic way ?
Thank you.
Richard
