HP P2000 G3 MSA System CLI Reference Guide 285
Policy
Recovery policy to invoke when threshold value is reached:
•
autoexpand
: Try to expand the snap pool by the
SizeToExpand
value. If the snap pool's
space usage reaches the percentage specified by its error threshold, the system will log Warning
event 230 and will try to expand the snap pool by the snap pool's
SizeToExpand
value
(below).
• If the snap pool is successfully expanded, the system will log Informational event 444.
• If the snap pool cannot be expanded because there is not enough available space in its
vdisk, the system will log Warning event 444 and will automatically delete the oldest
snapshot that is not a current sync point.
Each time the snap-pool's error threshold is reached and the system cannot auto-expand the
vdisk, the oldest remaining snapshot that is not a current sync point will be deleted. This behavior
occurs for each snap pool independently, based on its space usage.
•
deleteoldestsnapshot
: Delete the oldest snapshot.
•
deletesnapshots
: Delete all snapshots.
•
haltwrites
: Halt writes to the snap pool.
•
notifyonly
: Generates an event to notify the administrator.
SizeToExpand
•
size
: For the
autoexpand
policy, the size by which to automatically expand the snap pool
when the threshold is reached.
•
N/A
: The policy is not set to
autoexpand
.
