OPTIONS
-sp, --spare-disk
Specifies the dedicated spare disk or disks to assign, with a maximum of four. No space is
reserved on the selected disks.
-s, --size
Specifies the size of the array in MBs. If you do not use this option, the largest possible size is
used by default.
-ns, --no-sync
Disables background synchronization of redundant types when creating the array.
-ca, --cache
Specifies a cache setting for the array(s): read cache <r>, read and write-back cache <rw>, write-
back cache <w>, or no cache <nc>. The default is read and write-back cache <rw>.
-ms, --max-size
Prints the maximum possible size for an array without actually creating an array.
-n, --name
Identifies an array with a user-supplied name. The name can be up to 30 characters, but only 17 of
those characters display in the BIOS.
-p, --priority
Sets the background initialization task priority from 1 to 10, with 10 being the highest priority. For
redundant array types only.
-led, --leave-existing-data
Leaves the existing data on the disks untouched after the array is created. This option can be used
to try to recover user data when an array has been accidentally deleted or the configuration
information is lost but the data is still intact. Unless you immediately recreate the array after
deleting it and no other tasks have been performed, the likelihood of recovering data with this
method is very low.
-d, --disk
A required qualifier used with the --create option to specify the disk or disks to be included in the
array.
-sa, --scan-array
Specifies that a background array scan should be continuously run whenever the array is idle
(Default is off).
-z, --zero
Zero the array in the foreground. This method is faster than doing a background consistency
verifies if the array is a redundant type. For non-redundant types, the zero option can be used to
verify all blocks in the array can be accessed.
