You can configure Tivoli® Storage FlashCopy® Manager as a stand-alone configuration, and protect SQL Server workloads in a clustered environment that uses either shared disks or cluster shared volumes (CSV).
The VSSALTSTAGINGDIR path must point to an accessible directory on a shared disk, for example, X:\vss_staging, or to a cluster shared volume, for example, C:\ClusterStorage\Volume1\vss_staging. The VSSALTSTAGINGDIR option must be specified in the backup-archive client options file, baclient\dsm.opt, and in the Data Protection for SQL options file, tdpsql\dsm.opt, and the option argument must be the same. For example, X:\vss_staging is the absolute path to the VSS staging directory on a shared disk or a CSV that all cluster nodes can access.
Alternatively, you can navigate to the baclient directory and open either the dsm.opt or custom.opt file depending on whether the configuration wizard mode is in either default or custom mode. By default, the VSS Requestor dsm.opt file is located in the Tivoli Storage Manager backup-archive client installation directory, c:\Program Files\tivoli\tsm\baclient\dsm.opt. The location of the Data Protection for SQL options file is: c:\Program Files\tivoli\tsm\TDPSQL\dsm.opt.
