● A value that includes a space must be enclosed in double quotes.
[remote-password password]
Optional in console format; required for API format. The password of the user specified by the
remote-username parameter. If this parameter is omitted, the command prompts you to enter and
re-enter a value, which is displayed obscured for security reasons.
[remote-port-address remote-port-address]
Optional. Specifies a new FC WWN or iSCSI IP address for the remote system. IPv4 and IPv6 formats
are supported. If you specify this parameter you may not specify the name parameter.
remote-username username
The name of a user in the remote system. This must be a user with the manage role to remotely
configure or provision that system.
peer-connection-ID
Specifies the name or serial number of the peer connection to modify.
Examples Connect the current peer connection Peer1 to the remote system’s new IP address,
192.168.202.22, using the credentials of remote user John.
# set peer-connection remote-port-address 192.168.202.22 remote-username
John remote-password John1234 Peer1
Rename Peer1 to PeerCon1.
# set peer-connection name PeerCon1 remote-username John remote-password
John1234 Peer1

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 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 enable the overcommit feature, 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.
● When the overcommit feature is disabled, the host does not lose read or write access to the pool
volumes when the pool reaches or exceeds the high threshold value.
● When the overcommit feature is enabled, the storage system sends the data protect sense key
