   Table 1. Field Details

   Setting	Description
   Snapshot consistency group settings
   Name	Specify the name for the snapshot consistency group.
   Enable automatic deletion of snapshot images when...	Keep the check box selected if you want snapshot images automatically deleted after the specified limit; use the spinner box to change the limit. If you clear this check box, snapshot image creation stops after 32 images.
   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.
