Deduplication Database Hardware Refresh
You can change the location of the partition(s) of active or sealed DDB on the existing MediaAgent to a temporary location. This is useful in the following scenario:
- The disk hosting the DDB has to be upgraded to a high-performing disk storage media and the drives are currently unavailable.
Before You Begin
Before changing the location of the active deduplication database (DDB) make sure that:
- No DDB backup or DDB reconstruction jobs are running to the storage policy copy that is associated with the DDB move.
- Ensure that you have adequate space on the temporary location and on the new disk hosting the DDBs.
- Log on to the MediaAgent computer on which the DDB is hosted.
- Stop all MediaAgent services.
For instructions, see Stopping a Service.
- Ensure that there is no SIDB process running on the MediaAgent.
- For Windows, verify from the Windows Task Manager - Processes tab.
- For Linux, run the commvault list command.
- Copy all the content of the DDB (CV_SIDB folder and icl_label.txt file) to a temporary folder.
Make sure that permissions on the files or folders are also copied.
Note: Make a note of the drive letter where the DDB is located. This is required later to recreate the volume on the upgraded disk with the same drive letter.
- Upgrade the disk with a new storage media, such as SSD (solid state drive).
- Recreate the volume on the upgraded disk with the same drive letter.
- Copy the DDB content (CV_SIDB folder and icl_label.txt file) from the temporary location to the upgraded disk.
- Start all services.
For instructions, see Starting a Service.
