SET
mirrorset-name
Changes the characteristics of a mirrorset, including the addition and removal of
members.
Syntax
SET mirrorset-name
Parameter
mirrorset-name
Specifies the name of the mirrorset to modify. This is the same name given to the
mirrorset when it was created with the ADD MIRRORSET command.
Switches
COPY=FAST
COPY=NORMAL (Default)
Sets the speed at which the controller copies data to a new member from normal
mirrorset members when data is being mirrored to the storageset’s disk drives.
Specify COPY=FAST to allow the creation of mirrored data to take precedence over
other controller operations. When you specify COPY=FAST, the controller uses more
resources to create the mirrored data, and copying takes less time. However, overall
controller performance is reduced.
Specify COPY=NORMAL when operations performed by the controller should take
priority over the copy operation. If you specify COPY=NORMAL creating the
mirrored data has a minimal impact on performance.
