NAME
arraycfg - configures LUNs (logical drives) and physical disks
SYNOPSIS
arraycfg -L LUN { -a capacity | -d | -r newLUN }[-V][-?] array-id
arraycfg -D slot { -a | -d [-v][-R|-Z]}[-V][-?] array-id
DESCRIPTION
arraycfg is used to manage both the logical and physical configuration of the disk array identified by
array-id. Logical configuration involves creating, deleting, and renumbering LUNS (logical drives) on the
disk array. Physical configuration involves including or downing disks from the array configuration.
WARNING: Deleting a LUN will destroy all the data on the LUN. Backup all vital data before deleting a
LUN.
The array-id used to address the disk array can be the disk array serial number, the character device file
name of any LUN on the array (LUN 0 if no LUNs are created), or the alias text string assigned to the disk
array.
Options
arraycfg supports the following options:
-a capacity If -L is specified, create the indicated LUN. The capacity parameter indicates the size
of the LUN. By default, the size is specified in Mbytes. The size can also be specified in
Gbytes by appending a "G" to the value, or in Kbytes by appending a "K" to the value.
If
-D is specified, include the indicated disk in the array configuration. When per-
forming this operation, capacity is not included.
-d [ -v ][ -R | -Z ]
If -L is specified, delete the indicated LUN. The remaining options are not used.
If -D is specified, bring down the indicated disk. When downing a disk, the following
supplemental options are used
-v Specifies whether the down operation is destructive or nondestructive. This
determines whether or not the disk array will assume there is any valid data on
the disk when it is returned to the array configuration. If the -v option is
included, the down is nondestructive and the array assumes any data on the disk
that was not updated in the disk’s absence is valid. By default, the array per-
forms a destructive down and assumes no valid data remains on the disk when it
is returned to the array configuration.
-R Allows the disk to be downed even if a loss of redundancy would result, but not
data unavailability. When using this option, the disk array will continue to offer
full data availability but the disk array is not protected against another disk
failure. If
-R is not included, the command to down a disk will fail if it would
result in a loss of redundancy.
-Z Allows the disk to be downed even if data unavailability would occur. If
-Z is
not included, the command to down a disk will fail if it would result in data una-
vailability.
WARNING: Specifying the -Z option could cause the disk array to become una-
vailable.
-D slot Perform a physical configuration operation on the disk installed in the cabinet slot
identified by slot. Slot numbers must be of the form An or Bn, where A or B
correspond to a cabinet column, and n corresponds to a shelf position (1-6).
-L LUN Perform a logical configuration operation on the LUN identified by LUN.
-r newLUN Renumber the LUN specified by LUN to the value specified by newLUN. This option
is only used with the -L option.
-V Verbose mode displays additionalcommand execution, state, and/or status messages.
-? Display expanded usage message. This option overrides all others.
