Reserved capacity settings |
Alert me when... |
Use the spinner box to adjust the percentage
point at which the system sends an alert notification when the reserved
capacity for a snapshot consistency group is nearing full.
When the reserved capacity for the snapshot consistency group
exceeds the specified threshold, use the advance notice to increase
reserved capacity or to delete unnecessary objects before the remaining
space runs out.

Policy for full reserved capacity |
Choose one of the following policies:
- Purge oldest snapshot
image – The system automatically purges the oldest snapshot image
in the snapshot consistency group, which releases the snapshot image
reserved capacity for reuse within the group.
- Reject writes to
base volume – When the reserved capacity reaches its maximum defined
percentage, the system rejects any I/O write request to the base volume
that triggered the reserved capacity access.
