Hi Randy,
A few things:
1) You don't mention which version of the client you are running. If
you are using version 3.1 of the product, make sure you have the
3.1.0.8 client installed. If you are using version 3.7 of the
product, make sure you have the 3.7.1.03 client installed (this is
a fixtest level that fixes a problem in the 3.7 cluster support).
2) When you install the service on the cluster system, be sure to
specify /CLUSTERNODE:YES and /GROUP:clustername in the
DSMCUTIL INSTALL command. "clustername" is the name of the cluster
in which the machine participates. (Yes, I know that /GROUP is a
poor name for the option; eventually I would like to see this
fixed.) Also, the client options file (dsm.opt) that is used by
this service must have CLUSTERNODE YES in it.
3) When running DSMCUTIL SHOWPW or DSMCUTIL UPDATEPW for the node on
the cluster machine, you must specify the /CLUSTERNODE:YES and
/GROUP:clustername, just as you did when you installed the scheduler
service.
4) Do not "bounce" a node back & forth between CLUSTERNODE YES and
CLUSTERNODE NO, as this will wreak havoc with the encrypted
password in the registry (you will see symptoms like disappearing
node entries in the registry and authentication failures - rc 137 -
in dsmerror.log). If you configure a node for cluster support, then
always use the cluster support for that node.
5) The /CLUSTERNODE:YES and /GROUP:clustername options for DSMCUTIL
are applicable to scheduler services only. The web client services
(client acceptor, remote client agent) do not support these options.
We are planning on including this information in future documentation.

Andy

I have just installed our first cluster server and will be using ADSM to do
the backups for it. I have read through the Redbook on using TSM with MSCS
but what I am looking for are little things that I should look out for that
are not fully explained in the installation notes. The system that it is
being installed on is as follows:
Active - Passive
IBM 7000 series servers
4x 550 xeon processors in each
512Mb ram
Raid level 1e on the disk
