mirrorset-name
Assigns a name for the mirrorset. The mirrorset-name can consist of a
maximum of nine printable characters excluding commas and backslashes.
It is common to name a mirrorset MIRRn, where n is a sequentially assigned,
unique identifier. Other naming conventions are acceptable, but this naming
convention provides both the type of container and its unique identifier.
Switches
The following switches support the MIRROR command:
■ COPY
■ POLICY and NOPOLICY
These switches are described in the following paragraphs.
COPY=FAST
COPY=NORMAL (default)
Sets the speed at which the controller copies data to a new member from
normal mirrorset members if data is being mirrored to the storageset disk
drives:
■ Specify COPY=FAST to allow the creation of mirrored data to take
precedence over other controller operations. If 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 if you want operations performed by the
controller to take priority over the copy operation. If you specify
COPY=NORMAL creating the mirrored data has a minimal impact on
performance.
POLICY=BEST_FIT
POLICY=BEST_PERFORMANCE (default)
NOPOLICY
Sets the selection criteria the controller uses to choose a replacement disk
from the spareset if a mirrorset member fails.
