Hello all,

this will be my first time restoring a TSM server in DR facility.
Does any one one have good notes or simple direction i can follow?
like a step by step type of instruction..
We do use DRM feature of TIVOLI. Your help is greatly appreciated

Thank you in advance.

If you use DRM you should have a Recovery Plan File created by an job
executing "prepare" on the TSM Server.

The Recovery Plan File will tell you which Tapes are need for DR and
what steps has to be done after the TSM server itself has been
recovered.

Pinoy,

To be honest you really need to think this through yourself. It is to
big a subject for someone to just give you tips or notes on. There
are too many variables.

The first thing is for you to understand how to restore the TSM DB

dsmserv restore (I think from memory)

To be honest its all pretty straightforward although does take some
planning. Most TSM things are pretty simple and DR is no exception.

Personally what I do is copy my TSM config files and volhist.out etc
to a server at a different site. In a DR I can then access all my TSM
config and install TSM on a new server, restore my DB and then copy
onto it the config files, ie dsmserv.sys etc.

One tip is maybe to not set your prim tape pool to destroyed as if you
do this and then find a secondary tape is damaged you cant use the
prim pool to restore from. No good in a rel DR I know but in a test
youmay want to make use of a prim tape if part of the DR test is to
restore users data.

Its also a good time to check everything is being taken offsite that
should be.

Great advice Scott..

what i've doing everyday is tar the whole /usr/tivoli/* directory.
so when i get to the site i have all the files I need the TSM may look
for..

my draft:

1) install the mksysb and the non rootvg
2) untar my /usr/tivoli/
3) make sure the ATL is communicating with the TSM server
4) follow the directions in the PREPARE report
5) when do I set the offsite tapes destroyed once TSM is up?- Hide quoted text -

For number 5, yes once TSM is all up and running you can do this.
Although I think you can just set the prim pool to unavailable
instead of destroyed, that way you can always courier a prim tape to
the DR site should you need to read data from it for client restores.
As I said above you cant do that in a real disaster as your prim tapes
are toast. But in a test its something you can maybe do in case the
seco tape is not around, or unreadable etc.

What you should also do is make sure all your secondary pool tapes you
load are set to be readonly by TSM (even make them physically readonly
by turning the tape tab if possible). otherwise you may find some
reclamation or whatever starts and moves data about on the tapes which
of course the live TSM server wont know about.

I think you can set something in dsmserv.opt to stop schedules
running, I think its 'disablescheds yes' So put that in there before
you start TSM. This will stop admin schedules and backup scheds I
believe.

Something we never considered too much until recently was the prim
disk pools. We concentrated on just recovering TSM so we could
restore. But now many of a servers (clients) are split site, so in
actual fact we may not want to restore from TSM so much as get it
ready for client backups. In that case we of course need to make sure
all the disk pools are available as well.

Scott
