Creating LUNs
To create a LUN numbered 17 with a capacity of 30 Mbytes associated with
redundancy group 2, for an array with the alias of myArray, type the following
command:
armcfg -L 17 -a 30 -g 2 myArray
-x { true | false } Activates (true) or deactivates (false) the specified LUN. Performance can be
improved by deactivating any LUN you will not be using.
Disk Options (armcfg -D)
-D <FRULocation> Operation will be performed on the disk specified in <FRULocation>
-a Add the disk specified by <FRULocation>.
-d [ -v | -F] [-R | -Z ] Down the specified disk. The following options control the downing operation.
By default, the controller assumes that no valid data remains on the disk when it is
reinserted. The following options control behavior when the disk is reinserted.
-v - On reinsertion of the disk, the controller assumes disk data is valid except for
data written to the array since the disk was removed.
-F - The array will auto fail the disk specified by <FRULocation>.
By default, a down command will succeed only if downing of the disk does not result
in a loss of redundancy or data availability. This can be overridden with the
following options:
-R - Allow the disk to be downed if doing so would result in a loss of
redundancy but not data loss. Following this command the array will offer full
data availability but will be unable to protect against any subsequent disk
failure(s).
-Z - Allow the disk to be downed even in the case where data will become
unavailable. Caution should be exercised when using this option since data on
the array may be lost.
-r { true | false } Reset the specified disk using the indicated process.
If “true”, a Loop Initialization reset L_port loop primitive is used to reset the device
If “false”, a Target Reset Task Management function is used to reset the device.
-? Display extended help message. This option overrides all other switches.
