CLI Commands B–121
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 during copying.
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.
MEMBERSHIP=number-of-members
Sets the nominal number of mirrorset members to the number you
specify for the number-of-members value. A maximum of six members
can be specified.
