    Setting Description

    Alert me when…​

    Use the spinner box to adjust the percentage point at which System Manager sends an alert notification when the reserved capacity for a mirrored pair is nearing full.

    When the reserved capacity for the mirrored pair exceeds the specified threshold, System Manager sends an alert, allowing you time to increase reserved capacity.

    Note Changing the Alert setting for one mirrored pair changes the Alert setting for all mirrored pairs that belong to the same mirror consistency group.

    Policy for full reserved capacity

    You can choose one of the following policies:

    • Purge oldest snapshot image – System Manager automatically purges the oldest snapshot image in the consistency group, which releases the member's reserved capacity for reuse within the group.

    • Reject writes to base volume – When the reserved capacity reaches its maximum defined percentage, System Manager rejects any I/O write request to the base volume that triggered the reserved capacity access.

  5. Click Save to apply your changes.

Result

System Manager changes the reserved capacity settings for the member volume, as well as the reserved capacity settings for all member volumes in the consistency group.
