When in Data Protector media of a StoreOnce software store become expired, the used disk space is not released immediately. The disk space will be released once the media is overwritten or deleted. The housekeeping process running in the background to release the space will start only when the media is no longer used in Data Protector. Housekeeping requires time and the disk space is not released immediately. At the moment it is not possible to control the housekeeping process via Data Protector (see blackout window in StoreOnce hardware systems), however, it should not run during the time of running backups, as it will slow down the data throughput. Using the global variable DeleteUnprotectedMediaFreq
at least it is possible how often during the day expired media are deleted as a trigger for the housekeeping process. With the command omnimm -delete_unprotected_media
(for syntax see help of the command) you can manually control the deletion process.
Hi Daniel,
Can I use that command for other non StoreOnce VTL?
Hi Sean,
no the command is for B2D devices only (Catalyst) and cannot be used for regular libraries.
Best regards
Daniel
When DP Engineers fixed the “omnimm -delete_unprotected_media” with a release of DPWIN_00637 (Linux too!) so that it would delete “expired” media from a catalyst store, i believe they broke its ability to clear out media whose protection is classified as anything else, i.e. “Protection = None”. This command no longer processes any media except media whose protection is classified as “expired”.
Someone prove me wrong please because that is what I am experiencing. I have thousands of media in one catalyst store marked with “none” as their protection that will not delete and my space usage continues to climb on my store.
Has anyone seen any serious problems from implementing DPWINBDL_00703.EXE so far?
How to stop the housekeeping process at HPE Storeonce for a while. I want to export media and import in new Cell Manager in MoM with cmmdb. Old cell manager was lost.
