You can display summary and detail information for existing volume snapshots.
To display information on snapshots:
The Volume Summary page is displayed.
The Volume Details page for the selected volume is displayed.
The Summary page for the volume's snapshots is displayed.
As you monitor your storage, use the threshold notifications as a measure of how quickly the snapshot reserve space is being consumed. At several thresholds, the system generates messages to indicate the level of space left. The system reports the snapshot full percentage for each volume in 5% increments. When a volume's filled space reaches 70%, the system generates a Warning notification. At the 90%, 95% and 100% thresholds, the system generates a Critical notification.
Caution -
Do not allow the snapshot reserve space to run out of storage space. It is easier to prevent than to recover from an Out of Space error.
To release space, delete the oldest snapshot. If this does not create enough space, continue to delete snapshots in age order until enough free space is available. If deleting all of the snapshots is not enough, stop the application and back up the data.
