set pool
Description
Sets parameters for a virtual pool.
Each virtual pool has three thresholds for page allocation as a percentage of pool capacity. You can set the
low and middle thresholds. The high threshold is automatically calculated based on the available capacity of
the pool minus 200 GB of reserved space.
When the low or middle threshold is exceeded, event 462 is logged with Informational severity. If the high
threshold is exceeded and the pool is not overcommitted, event 462 is logged with Informational severity. If
the high threshold is exceeded and the pool is overcommitted, event 462 is logged with Warning severity. If
the pool’s capacity threshold is reached, event 462 is logged with Error severity. When pool usage falls back
below any threshold, event 463 is logged with Informational severity.
NOTE: If the pool size is small (approximately 500 GB) and/or the middle threshold is
relatively high, the high threshold may not guarantee 200 GB of reserved space in the pool.
The controller will not automatically adjust the low and middle thresholds in such cases.
You can also set overcommit, which controls whether storage-pool capacity may exceed the physical
capacity of disks in the system. If you try to disable overcommit and the total space allocated to thin-
provisioned volumes exceeds the physical capacity of their pool, an error will state that there is insufficient
free disk space to complete the operation and overcommit will remain enabled. If your system has a
replication set, the pool might be unexpectedly overcommitted because of the size of the internal snapshots
of the replication set. To check if the pool is overcommitted, view the over-committed and over-committed-
numeric properties shown by the show pools command in API mode. You can also view the Pool
Overcommitted value in the PowerVault Manager, as described in help for the Pools topic.

Parameters
[low-threshold #%]
Optional. Sets the low threshold for page allocation as a percentage of pool capacity. This value must be less
than the middle-threshold value. The default low-threshold value is 50%.
[middle-threshold #%]
Optional. Sets the middle threshold for page allocation as a percentage of pool capacity. This value must be
between the low-threshold value and the high-threshold value. The default middle-threshold value is 75%.
[overcommit enabled|disabled|on|off]Optional.
• enabled or on: The allocated size of the volumes can exceed the physical capacity of the pool. When
stored data approaches the limit of physical capacity, the administrator can add more enclosures to the
system. This is the default.
• disabled or off: The allocated size of the volumes cannot exceed the physical capacity of the pool.
NOTE: If you try to disable overcommit and the total space allocated to thin-provisioned
volumes exceeds the physical capacity of their pool, an error will say that there is
insufficient free disk space to complete the operation and overcommit will remain enabled.
