Considerations:v Use the collocatebyfilespec option only if the storage pool is going directly totape. If you use this option going to a disk storage pool, you could affect someload balancing, and therefore, performance.Supported ClientsThis option is valid for all Windows clients. The server can also define this option.Options FilePlace this option in the client options file (dsm.opt).Syntax►►COLlocatebyfilespecNoYes►◄ParametersYesSpecifies that you want the Tivoli Storage Manager client to use only oneserver session to send objects generated from one file specification. Therefore,if you store the data to tape, files for each file specification are stored togetheron one tape, unless another tape is required for more capacity. Restoreperformance can increase as a result.No Specifies that the Tivoli Storage Manager client can (depending on theexecution dynamics and on the setting of the resourceutilization option of 3 orhigher), use more than one server session to send the files from one filespecification. This is the default.Backup performance might increase as a result. If the files are backed up totape, files are stored on multiple tapes. Generally, the files specified in the filespecification are still contiguous.ExamplesOptions file:collocatebyfilespec yesCommand line:-collocatebyfilespec=yesThis option is valid only on the initial command line.
