Retiring the DS-System Primary Storage Location (Backup Root)


Creation Date: July 21, 2008
Revision Date: January 20, 2009
Product: DS-System

Summary

This article describes the process that must be followed in order to retire the DS-System Primary Storage Location. The Primary Storage Location is the location specified by the "Backup Root" parameter in the DS-System Configuration file (dssys.cfg). By default, after a DS-System installation, the Primary Storage Location is the storage location with ID 1.

WARNING: Normally, you should never change the Primary Storage Location. In the event of hardware failure on the Primary Storage Location, you must configure the replacement file system with the same absolute path (name/IP address, share, folder) as the original one. Then you must restart the DS-System in DR mode (Advanced Configuration Parameter "DisasterRecoveryMode" = 1) in order for DS-System to rebuild the storage links for every backup set in the replacement location.

Details

All Extensible Storage Locations contain the following:

The Primary Storage Location also contains the following folders:

Changing the Primary Storage Location

This is possible in very rare situations (like if you need to retire the Primary Storage Location). This requires manual changes to the DS-System database, therefore it must be done very carefully. This also requires a restart of the DS-System.

1. Suspend activities on DS-System (Setup Menu > System Activities: Disable).

2. Setup Menu > Storage > Extensible Storage. From the Extensible Storage Locations screen, make sure there are only two Storage Locations in the same Group as the Primary Storage Location:

3. Highlight the current Primary Storage Location and click Retire. (For more information, see "Retire Storage Locations".)

4. Copy the dump, Licenses, Logs, and cluster folders to the new Primary Storage Location.

5. Edit the DS-System Configuration file (dssys.cfg). Change the following values to the path of the new Primary Storage Location:

6. Stop DS-System service / daemon.

7. Manually edit the DS-System (dssystem) database (MS SQL or PostgreSQL) with the following SQL statement:

DELETE FROM Storage_Locations WHERE ID=<primary_storage_id>

where <primary_storage_id> is the lowest corresponding ID from the Extensible Storage Locations screen list (normally it will be "1").

Note: This command removes the existing Primary Storage Location. The next lowest ID number becomes the new Primary Storage Location. (e.g. if you delete ID #1, if there is an ID #2 it becomes the new Primary Storage Location.) The new Primary Storage Location must be the same one where the links were re-assigned in step 3.
WARNING: DO NOT MAKE ANY OTHER CHANGES TO THIS TABLE OR THE DATABASE.

8. Start DS-System service / daemon. Verify there are no errors.
