If classes, groups, and slices are related to master volumes or proxy volumes, operations that change the class attributes, change the group configurations or attributes, or handle the slices cannot be performed. To perform such operations, cancel the relationship between the master and the proxy once.
For objects that are related to the master and the proxy:
Master volumes can be started or stopped.
Proxy volumes that are parted from the master can be started or stopped.
New volumes can be created within a group other than the master group or the proxy group and existing volumes other than the master or the proxy can be removed.
The hot spare function is available for groups with master volumes. Spare disks are not connected to groups with proxy volumes.
The following operations can be performed, but the operation will result in an error if copying is in process, or there is an EC session, a BCV pair, or an SRDF pair, between the master and the proxy.
Attributes of master and proxy volumes can be changed with the sdxattr -V command.
A disk connected to a group with master volumes and proxy volumes can be made exchangeable with the sdxswap -O command, and after swapping disks, the swapped disk can be returned to a usable state with the sdxswap -I command.
Synchronization copying of the master volume or the proxy volume separated from the master volume can be started, cancelled, interrupted and resumed, and the parameters of the synchronization copying changed. However, synchronization copying between volumes or its parameters cannot be changed.
Master volume can be restored with the sdxfix -V command.
For EC sessions, BCV pairs, and SRDF pairs between the master and the proxy, check the FUNC field displayed with the sdxinfo command. If the master and the proxy are in parted status, a copy session can be canceled with the sdxproxy Cancel command.
