When theclusterdisksonly option is specified as no, you must explicitly define the backupdomains. When the clusterdisksonly option is specified as no, the Tivoli StorageManager Backup-Archive client also bypasses enumeration of cluster resources inorder to determine which resources represent cluster drives. This can be beneficialif initialization of the Backup-Archive client exhibits long delays.Supported ClientsThis option is valid for all Windows clients.Options FilePlace this option in the client options file (dsm.opt).Syntax►►CLUSTERDISKSOnlyYesNo►◄ParametersYesSpecifies that the Tivoli Storage Manager only allows the processing of clusterdrives that have a drive letter.
