on the left and total (GB) capacity remaining on the right.
4. Click OK.
For information about configuring the free capacity alert threshold for a storage pool, see
“Changing storage pool free capacity alert threshold” on page 96.
Storage pool capacity is evaluated against the configurable free capacity alert threshold. When the
free capacity of a storage pool drops below the threshold:
• A notification is sent to any notification groups configured to receive this type of alert. For inform-
ation about configuring notification groups, see “Configuring event log notifications” on page 355.
The notification is repeated every five minutes.
• Creation of new virtual disks from the storage pool is blocked. This includes temporary virtual
disks. Therefore, PiT creation is also blocked.
• Virtual disks from the storage pool are expanded by chunks that are limited to 1 GB, and not ac-
cording to the normal algorithm which uses 5% expansion.
