Retire & Delete Storage Location(s)
Summary
Extensible storage locations can be retired and then deleted. This feature allows customers to stop using a specific storage location and to migrate any data from it to another storage location (or locations). This facilitates decommissioning of storage locations and hardware replacement for the DS-System Online Storage.
Details
Once a storage location is marked as <RETIRED>, that storage location will no longer receive new data from the DS-System.
The storage location is still required by the DS-System in order to be able to provide data for restores or for generation processing. Therefore the DS-System software will continue its constant monitoring of the availability of this storage location.
In order to move the data from a retired storage location to other storage locations, the "Retire Storage" process must be triggered (Setup Menu > Storage > Retire Storage Monitor: Start):
- Data at backup set level, as well as client libraries are moved to the Storage Group configured for that DS-Client.
- Data in account libraries will be moved to the Storage Group configured for that account.
- The public libraries are moved to the <DEFAULT> Storage Group.
- The "Retire Storage" process balances the amount of data moved across all the storage locations (belonging to the same Storage Group).
Once all the data has been moved from a retired storage location, that location can be marked as <DELETED>. A <DELETED> storage location will be removed from the Extensible Storage Locations List the next time the DS-System restarts. In the meantime, DS-System will continue to verify availability of the <DELETED> storage location. DS-System will not send data to this storage location, but it must be available or else DS-System will suspend its operations.
- Once the DS-System services/daemon is restarted, a <DELETED> storage location will disappear from the Extensible Storage Locations List.
- While a storage location is in <RETIRED> or <DELETED> status, it can be easily reactivated by assigning it to a Storage Group in the Edit Storage Location screen (Setup Menu > Storage > Extensible Storage: Edit).
In order to retire and delete the primary storage location for a DS-System, please follow the instructions in the Knowledge Base article "Retiring the DS-System Primary Storage Location (Backup Root)".
