Storage Center: How to troubleshoot secondary storage systems in Conservation Mode.

Alert:

Secondary Storage "storage name" Conservation Operation, No new volumes, early replay expiration, Index: "number"

System with compression enabled has entered Conservation Mode. No new space is provisioned, and the system uses logic to more aggressively recover space through Point in Time Copy (PITC) expiration.

Storage Center has entered Conservation Mode because remaining free space is critically low. No new volumes can be created. Storage Center begins to aggressively expire replays. Immediate action is necessary to avoid entering Emergency Mode, which halts all write I/O to Storage Center until sufficient space is available.

To resolve conservation mode, you must reclaim consumed space or add more capacity. After Conservation Mode has been resolved, review the system capacity requirements and consider adding disk space.

To reclaim consumed space, perform each of the following steps and wait a few minutes before reassessing available space:

1. Check the Recycle Bin and empty if applicable.
2. Identify and expire unnecessary replays. Do not expire the most recent two replays.
3. Delete unnecessary volumes and empty the Recycle Bin.
4. Run whitespace recovery on hosts where applicable.
