MIRROR disk-device-name1 container-name
MIRROR disk-device-name1 container-name
Allows you to convert a physical device to a one-member mirrorset.
Format
MIRROR disk-device-name1 container-name
Parameters
disk-device-name1
Specifies the name of the physical device that you wish to convert to a one-
member mirrorset. The device must be part of a unit.
container-name
Specifies the name that is used to refer to this mirrorset. The name must start
with a letter (A–Z) and can then consist of up to eight more characters made up
of letters A–Z, numbers 0–9, periods (.), dashes (-), or underscores (_), for a total
of nine characters.
Description
The MIRROR disk-device-name1 container-name command allows you to convert
a physcial device specified by disk-device-name to a mirrorset with one member.
The mirrorset name is specified by container-name. This command can be used
on devices that are already members of higher level containers (stripesets or
units).
After you convert the device to a mirrorset, increase the nominal number of
members with the SET mirrorset-container-name MEMBERSHIP=number-of-
members command. Use the SET mirrorset-container-name REPLACE=disk-
device-name command to actually add more members to the mirrorset. Refer to
SET mirror-container-name for details for using the MEMBERSHIP= number-of-
members qualifier versus the REPLACE= disk-device-name qualifier.
NOTE
When this command is used to create mirrorsets from stripeset members
that were created before HSOF Version 2.5, the stripeset will then be
incompatible with prior firmware versions.
Qualifiers
COPY= copy_speed
The COPY qualifier allows you to specify the speed at which mirrorset copies are
performed. You may specify either NORMAL or FAST.
NORMAL uses relatively few controller resources to perform the copy, and has
little impact on controller performance.
FAST uses more controller resources, which reduces the time it takes to complete
the copy, but also reduces overall controller performance.
