Karel,
How do you deal with the fact that the mount point name changes when the
cluster groups moves from one node to another? We were thinking about having
two seperate dsm.opt files. Each would have the domain statments that list the
mount point names based on the server name. Then we were going to have a *.bat
file run as a preschedule command that would rename the mount point's file
space name on the TSM server so that the data always got backed up to the same
file space no matter what server the mount point was on. Did you do anything
like this? Or, do you just let the mount points backup to two different
filespaces. Remember the file space name has the complete path in it which
includes the server name which will make it look like a different mount point
based on what server it is mounted from.

Hi,
Read about it after the my first Windows 2003 cluster server, with mounted
disks, as ITSM back-up client. Normal clusters I had done that before, so I did
the standard config:
- Install BA client on the cluster controlers;
- Setup the back-up of the clustercontrolers (clusternode=no and domain only
local stuff);
- Setup cluster node (clusternode=yes and only cluster stuff).
And the last would not work as before. Mountpoint are on windows local so the
back-up would create \\controlereA\mp and after the switch \\controleB\mp.
After a while I though lets look in the change history of the newest ITSM
client at that time and found the (for me) new option CLUSTERDISKSONLY and some
example combinations of
CLUSTERNODE YES/No
CLUSTERDISKSONLY NO/Yes
Now I use the
CLUSTERNODE YES
CLUSTERDISKSONLY NO
And define every mp on the clusternode.

Karel

It looks like this option is used to allow the local disks to show up as well
when you have "CLUSTERNODE YES" in the dsm.opt file. This may get us to a point
where we can move from backing up the mount points on one node in the cluster
to backing them up under the node for the cluster group. However, our real
problem still sits with how the mountpoints themselves show up to the OS. The
mount point name has the local server in it (ex
\\serverA\Data\Accouting\Payable). When the cluster group moves to SERVERB the
mount point name changes to include that server name
(\\serverB\Data\Accounting\Payable). From the users perspective the mount point
itself is still Payable but becuase TSM includes the entire path in the
filespace name for the mountpoint simply allowing them to be backed up isn't
enough. As you can see I'd need to two seperate DOMAIN entries based on which
node in the cluster the group was mounted on.
Did you suggest this option becuase you read about it or are you using it? We
may test it but if the data is going to still backup under a different file
space name based on what side of the cluster the group is on we don't think
that is any better than what we have now (backing it up through the physical
server).

Hi,
In Windows 2003 and the newer ITSM clients there is one extra option.
See the client doc for extra info.
CLUSTERNODE YES
CLUSTERDISKSONLY NO

Subject: Clustered Mount points don't show up as clustered in TSM
I have a cluster that has two separate two node file clusters. These clusters
have both clustered disk and clustered mount points. These started out as
normal Microsoft Windows 2003 file clusters but then the added Veritas Volume
Manager to the mix.
With Veritas Volume Manager instead of each disk and mount point being a
separate clustered resource when you look at them in cluster administrator
there is a single clustered resource called "Volume Manager" or something like
that. Then on the properties\parameters tab of that clustered resource you see
all the disk and mount points.
My problem is that when I have "ClusterNode Yes" in the dsm.opt file and launch
the GUI using it, I see ever single clustered disk as I would expect but none
of the mount points show up. Then when I set "ClusterNode No" I see the local
disk and the mount points. The scheduled backup also reports an error "Not
Clustered Disk" when it trys to backup the mount points when "ClusterNode Yes"
is set in the options file it uses.
This seems to be a simple problem where they just have to fix the mount points
and set them up correctly. However, those mount points fail back and forth with
the cluster and when they do everyone can access them as they should. So the
customer feels that the mount points must be setup correctly. The mount points
themselves are all created on disk that is clustered. Also, just like normal
mount points when TSM gets to that folder in the file structure it does not
back up the data through the disk drive because it expect the data to be backed
up through the mount point.
I'm wondering if there is any chance anyone else has run into this? If not then
I was wondering if anyone else has mount points being backed up by TSM on a
regular Windows 2003 cluster without Veritas Volume Manager.
If I can at least confirm that in a non-Volume Manager solution the mount
points do show up as "Clustered" then I can lean more on Veritas to explain why
theirs show up differently.
For now we are backing up the mount points through the single local node name
that backs up the physical server and local disk. I am thinking about trying to
create a options file on the clustered disk with "ClusterNode No" and then
seeing if I can actually go through and create a client acceptor service and
client acceptor cluster resource.
I've only ever created these two things with options files that had
"ClusterNode Yes" before.
Thanks,
Kyle
