The hsmmultiserver option enables and disables migration and backup in an environment of multiple Tivoli® Storage Manager servers.
You can enable migration and backup from a single file system to multiple Tivoli Storage Manager servers. You must set hsmmultiserver=YES for each Tivoli Storage Manager for Space Management client in the GPFS™ cluster.
If you set hsmmultiserver=NO, all of the command options for the multiple-server environment are disabled. When you set hsmmultiserver=NO, you can recall files only from the migration server that is configured in the dsm.sys options file. If a file was migrated to a Tivoli Storage Manager server other than the migration server that is configured in the dsm.sys options file, you cannot recall the file.
The option is available only for AIX® GPFS clients and Linux GPFS clients.
Place this option in the client options file dsm.opt.
