Parameter Description
driveMediaType The type of drive media that you want to use for the
mirror repository subsystem. Valid drive media are
these:
v HDD – Use this option when you have hard drives
in the drive expansion enclosure.
v SSD – Use this option when you have solid state
drives in the drive expansion enclosure.
v unknown – Use if you are not sure what types of
drive media are in the drive expansion enclosure.
v allMedia – Use this option when you want to use
all types of drive media that are in the drive
expansion enclosure.
Use this parameter when you use the
repositoryDriveCount parameter.
You must use this parameter when you have more
than one type of drive media in your storage
subsystem.
freeCapacityArea The index number of the free space in an existing
subsystem that you want to use to create the mirror
repository logical drive. Free capacity is defined as the
free capacity between existing logical drives in an
subsystem. For example, an subsystem might have the
following areas: logicalDrive 1, free capacity,
logicalDrive 2, free capacity, logicalDrive 3, free
capacity. To use the free capacity following logical
drive 2, you would specify:
freeCapacityArea=2
Run the show subsystem command to determine if a
free capacity area exists.
repositoryDriveCount The number of unassigned disk drives that you want
to use for the mirror repository logical drive.
enclosureLossProtect The setting to enforce enclosure loss protection when
you create the mirror repository logical drive. To
enforce loss protection, set this parameter to TRUE.
The default value is FALSE.
drawerLossProtect The setting to enforce drawer loss protection when
you create the mirror repository logical drive. To
enforce drawer loss protection, set this parameter to
TRUE. The default value is FALSE.
T10PI The setting to specify that an subsystem, and the
logical drives within the subsystem, has T10 PI
(Protection Information) to help you ensure that the
data maintains its integrity. When you use this
parameter, only protected drives can be used for the
subsystem. These settings are valid:
v none—The subsystem does not have T10 PI
(Protection Information).
v enabled—The subsystem has T10 PI (Protection
Information). The subsystem support is protected
information and is formatted with protection
information enabled.
