I just called IBM Level 1 ( dial-a-pray ) and asked for advice
about migrating a user population from a 3466-C00
with TSM 3.7.2. to a 3466-C01 with TSM 4.1.x.
ANd essentially the answer was:
"good luck, we won't help you, ....
unless you want to pay our consultants more money.
(P.S> but you can call us back when you get error messages.)
I paid for a maintenance contact that's suppose to go beyond
defect support but migration isn't included in that help.
So I now turn to the community for help. HELP! :-)
Here's the story.
I've got a 3466-C00 at TSM 3.7.2 with 1200 users
5 terabytes of 3590 onsite-TAPEPOOL and the same
offsite. (backup no archive) and a 30 GB DB at
80 percent (i.e. 25 GB used)
I've got a 3466-C01 at TSM 4.1.x that's bolted down
to the floor and ready to go. With double the resources.
THe new 3466-C01 is TOTALLY replacing the 3466-C00 for now.
My tentative plans now are:
take the system 'off the air' for my users,
run backup stg tapepool copypool
backup stg diskpool copypool
do a migration diskpool to tapepool
(turning off collocation to expedite) down to zero.
backup db to a 3590 (twice)
attach the 3494 to the new system
take db tape over to the new 3466 and do a restore db.
dsmserv upgradedb (to adjust the 3.7.2 to be 4.1.x useable)
return to production with a new system!!!
I was hoping to do an UNLOAD DB and RELOAD DB but IBM
reminded me that it will take a day or two and then
its HIGHLY recommended that I also perform an AUDIT DB
which will take from 2 days to 30 days more. Yes that's
not a type-o one month to do an audit. So its now out of
the question although I'd love to give it a stab.
I was wondering if I should do other extras.
Should I delete the diskpool on the old system before
doing the backup db? Maybe delete other 'customizations'???
How receptive is a new empty system
to a db restore when its not the original system backed up??
suggestions, pointers to doc, and any other info will be
greatly appreciated.
thanks ...
