Joni --
I can't help with the DR Manager because we don't use it -- back in the
ADSM 2.x days it seemed to pricey to us and I couldn't see anything it
was doing (then) that we couldn't do on our own. I haven't looked at it
since, as our processes work.
But -- there is a bit of prep work required before you're ready to use
the DR Manager at D/R, and I can help with some of that.
First you need to restore the TSM environment. To assist in this, I have
a /DR directory on my root volume. Once a week I snapshot my TSM volume
group info to this directory: lsvg adsmvg >/DR/adsmvg.vglst and lsvg -l
adsmvg >/DR/adsmvg.lvlst. These allow rebuilding the volume group from
scratch if the automated process fails. I also run a savevg: savevg4vp
-I -e -f /DR/backup.adsmvg adsmvg. The exclude file ('-e' option)
contains /* -- exclude everything -- so all that gets created is the
meta-data for the vg. Now, when we run our weekly mksysb, we have
captured the data required to recreate the TSM volume group.
Now - at D/R.
Restore the AIX environment. We boot to service mode from CD and select
'restore system from a backup tape'; this will 'clone' the system,
getting any additional device drivers required for the hardware from the
CD. Then do a restore of the tsm vg: restvg4vp -f /DR/backup.adsmvg
<list of hdisks to use>. (The '4vp' is because we run SSD and multiple
paths to our ESS).
And now you're ready to recover your device config and volume history,
make any changes required to the device config, and restore the TSM
database. These are covered (IIRC) in the DR Manager scripts and
procedures, so someone else needs to step in here :-)

Hello All!
I believe that I am a little confused as to what/how DR Manager is and
works? I have looked at the manual, but things still don't make sense to
me
and I didn't want to wait until everything was configured due to the
fact
that I might be having a DR drill in December and we haven't even begun
moving things to the new environment.
1a. I first looked at define machine and it appears as if I have to
define
the TSM server and all nodes that I wish to restore at a DR site?
1b. Then you define the machine node association which seems as if you
just associate all of the nodes to the tsm server that you wish to
restore
from. Why is this needed? You would think that this is naturally
assumed
since this is where it has been backed up/defined...
1c. Define Recovery Media - not quite sure what this is... There is a
type
of boot or other? I'm not quite sure what this section is for? It's
not
very clear!
1d. Define Media Machine Association - Still confused about this
portion
as well. When it is stated that the recovery media is to: Select the
name
of the recovery media to be associated with one or more machines. Do
they
mean TSM server machines or node machines?
2. DRM Offsite Recovery Media - Currently we just take all of our tapes
that have been vaulted to the DR site that were created before the DBB
that
we use for our DR. I'm not quite sure what the commands portion of this
querying does? Why/what would you specify here?
3a. Create Recovery Plan File - Where do companies usually store this
file? When you go down to DR, where do you begin? I mean, what is the
starting point? Where do you begin?
3b. Do you use a dbbackup or a dbsnapshot? Why would you ever want to
use
a snapshot? You first have to restore the entire db before moving on...
4. How often do you create the plan and how long do you retain the
plans?
I am sorry for my ignorance, but I am moving to a brand new TSM AIX
5.2.2.5
environment from the mainframe and everything is very cloudy. Currently
we
just restore our TSM envrironment by restoring our DB & recovery log
volumes and starting up the tsm server, but now everything has changed
and
I'm not really sure how to restore this new environment or even where to
begin. If anyone is willing to share a step by step plan/process of
your
recovery I would appreciate it! It might give me a direction on
how/where
this will be accomplished. Thank you in advance!
