Using MainView SRM DMS2HSM

The MainView Storage Resource Manager (SRM) DMS2HSM product automates the conversion of DMS archived data sets to HSM.

The DMS archived data sets are restored to a pool of volumes specifically allocated for the conversion process. The migration to HSM of the restored data sets is automated by monitoring the volumes' free-space and forcing the HSM migration to second-level storage when utilization thresholds are reached.

The DMS2HSM conversion program works in conjunction with three other products from BMC:

  • The MainView SRM Allocation product, which forces the pooling of the restored data sets to specific staging volumes

  • The MainView SRM Automation product, which monitors the staging volumes for free space and issues an operator command to start volume-level migration

  • The MainView SRM Reporting product, which is used to force HSM to migrate the conversion data sets to Migration Level 2

DMS2HSM creates the DMS Restore jobs, an exception report of data sets that were bypassed, a tape pull list and a statistics summary of the conversion process. The reports can be used to determine the number of tapes to be processed, the number of data sets, and the amount of storage the converted data sets will utilize. An option of the conversion program will produce only the tape pull list and statistics report.
