Backup Central

Hi All

I'm involved in a consolidation exercise of a TSM environment that has
"just growed" over the last 15 years, and features multiple TSM 5.5
servers running on AIX on various P4 and P5 hardware. These are to be
moved, with as few changes as possible, to new P7 hardware, at a new
data centre. I'm also under the pump to get this done because of the
contract ending with the old data centre.

Migration to TSM 6 would take too long and is outside my brief. Because
of the unplanned server sprawl, most of the servers use port 1500, and I
don't have time to visit all the clients to update them to use a
different port. Also, given that the new hardware is so much better than
the old, it seems a waste to have two disk and two tape HBA ports
dedicated to each server in its own LPAR. So, I've hit on the idea of a
reasonably large TSM LPAR with the instances running in WPARS inside it.

Is anyone running TSM 5 in WPARS? I'm interested in any problems you
might have had, war stories, gotchas, and also any "yep works fine for
me" reports.


Many Thanks

Hi Steve,

I'm a bit out of your subject on TSM in WPARS but have you consired using the virtualisation features available on the Power Systems : NPIV to share FC cards, vSCSI to share boot disks via VIOS, IVE/HEA or SEA for network access..?

I don't think there are any major issues, but if you need access to tape drives you must have physical HBA's in each WPAR if you want to run an officially supported configuration. Virtual HBA's work, but are not officially supported, so if you run into any issues you might be on your own.

How about the performance in WPAR?

That is saying virtual NPIV adapters are OK.

Thanks Guys

My AIX Guru said that WPARs are more trouble than they are worth and
there are complexities as each instance is on a different subnet, but
the WPARs must all be on the same subnet. Thus we have shelved that
idea for now.

Steve.

Run them as multiple TSM instances in a single AIX image. Works fine
under TSM 5.5, but it's even easier in TSM 6 than in previous versions,
and it's lower overhead, easier management, etc. as long as you get your
naming conventions right to keep them separate. Set it up with a Library
Manager and then you won't be wasting HBAs or tapes in the scratch pool.
The only downside is all the TSM instances in a single AIX instance have
to be at the exact same TSM release level.

So a strategy that might serve your client well into the future could be
to set up two LPARs, one with TSM 5.5, and the other with TSM 6.X. This
only wastes one set of HBAs etc. A Library Manager must be at the same
or higher release level than all of its Library Clients. You could set
up the Library Manager as the first TSM 6 instance in the TSM 6 LPAR,
which could then allow for an orderly future migration of all instances
to TSM 6. We currently have a 6.2 Library Manager serving a mix of 6.2
and 5.5 Library Clients. This is how we are migrating to TSM 6 - Library
Manager first.

xinetd can solve your port 1500 collisions. All you need is separate
NICs. The users continue to specify port 1500, but xinetd can change
that to 1501, 1502, 9997... within AIX so that each goes to the intended
TSM server image. We do this on one AIX system that hosts two TSM 5.5
instances, and on another that hosts two TSM 6.2 instances. Just beware
of how much CPU xinetd can consume with the heavy net traffic of TSM
backups, however CPU cycles may not be an issue on that new P7 machine.

We use VIO/NPIV based tape drives for a bunch of storage agents. Once
setup and working it works well. We ran into several bumps along the
road:

1) We had to double the vio server memory (1g to 2gb I think).
2) We had to patch VIO to a newer level.
3) There are limits to the number of tape drives you can define in a lpar
this way. I'm thiniking 62 or so - don't remember exactly. It's a limit
on scsi targets. Every tape drives is a separate scsi target.
4) I also think there is a total limit on scsi targets across all lpars
defined to a vio based hba.
5) Learning about how vio handles targets and how to clear them. To
clear/reset the vio targets you have to drop the fcs adapter in the lpar.
Delete/recreating a rmt devcie in the lpar doesn't do it.

We've still had problems with loosing npiv WWN's. Somehow the vio
mappings have got lost such that we had to get all new wwn's in the lpar.
To say the least this caused pain!
