Moving TSM-Backup and all its data from one Cluster to an other Cluster

[obiwan2]

Hi Guys,

I have a very "nice" problem and I really need your help ....

The situation:
- we had an "old" Windows-Clustersystem (Windows Server 2000)
- the data was held on an Enterprise Virtual Array (EVA)
- TSM-Nodename: CLUSTERA
- Domain: G:
- the filespace was \\clustera\g$

Now comes the NEW Cluster:
- the new Windows-Clustersystem is a Windows Server 2008 R2 Enterprise System
- the data is now held on a NEW EVA-System, but was copied with a tool called FastCopy (equ. to RoboCopy)
- TSM-Nodename: CLUSTERB
- Domain: F:

To keep the old backupdata (with all the versions of backupfiles) I did the following:
1. renamed CLUSTERA to CLUSTERA-OLD
2. renamed CLUSTERB to CLUSTERA
3. renamed \\clustera-old\g$ to \\clustera\f$
4. changed the old "domain G:" to "domain F:" in the dsm.opt for the clusternode
5. changed all paths to logfiles etc. in the dsm.opt for the clusternode

After starting the dsmcad and the scheduler by switching to "online" in the cluster-admin all things seemed to be ok !!!
BUT.........one day later I could see the following results (for example):
3511.snd 27,65 MB Backed Up 06/06/2007 (therefore an inactive version)
3511.snd 27,65 MB Backed Up 07/23/2012 (as it is on the EVA-system...the active version)

3512.snd 7,14 MB Backed Up 06/06/2007
3512.snd 7,14 MB Backed Up 07/23/2012

and so on.......and so on.
Nearly every file (!) is now backed up again ... although it already exists in the backup !!!

Were the steps that I've done ok or is there a mistake ???

Thanks for any hint !!!!!

which file flags did you copy with FastCopy?

 

[obiwan2]

All of them....
-------------------------------------------------------
Just an idea: Is the reason -MAYBE- the new domain F: ?

If the old HL_NAME was G:\35xx and --due to using the new domain-statement-- the new HL_NAME is now F:\35xx, then the reason is -in my opinion- absolutely clear ! Then it's a new drive that TSM was never known....

 

[inestler]

you are absolutely right

 

[obiwan2]

Thank you !!

I thought as much ! But I wasn't absolutely sure ... now I am !

Hi

We have a similar situation where we are moving our data from one array to another array and will be presented to the same host with the same mount point, will this force TSM to trigger a full backup or will it just continue running incremental backups ??
