We are using:
1) the first dsm.opt file on drive C: of the first cluster node (to backup 
Windows and installed software);
2) the second dsm.opt file on drive C: of the second cluster node (to backup 
Windows and installed software);
3) additional dsm.opt file for each cluster resource group located on drive 
owned by resource group (to backup Exchange database).
In addition, we are using dedicated node names and schedulers for each cluster 
node and cluster itself.
Scheduler services for cluster resource groups must be part of cluster resource 
group to be moved together with resource group.

Subject: [ADSM-L] DSM.OPT file location for backing up cluster resources.

Hello,

I was reading this document about configure BA client for cluster environment.

http://publib.boulder.ibm.com/tividd/td/TSMC/GC32-0788-02/en_US/HTML/ans60021.htm

1) For backing up cluster resources, the document recommends to.locate the 
option file on one of the disk drives that are owned by the cluster group.

Question : When installing TDP for Exchange and to backup the virtual Exchange 
server, I assume it is also advisable to place the dsm.opt file in one of the 
disk drives owned by the cluster group. Is this correct?

Thanks
