Examples of the configure array command J–5
J.5 Examples of the configure array command
Example 1:
The following example configures the arrays attached to the administration and MDS server (arrays 1 and
2 in this example) to support one file system:
sfs> configure array 1,2
The command configures the arrays as follows:
• The administration LUN and the spare administration LUN are each 40GB in size (this is the default
size).
• A service LUN or spare service LUN for the server pair is automatically created on each array.
• The arrays are configured with one MDS LUN in each disk group; the default is to create one disk
group on an array, therefore one MDS LUN is created on each array.
• ADG redundancy is used (by default), which allows eleven disks (the default) to be used in the disk
group.
force Forces the configure array command
to ignore the status of the array’s cache.
The default is no.
The configure array command
performs status checks on the array before
proceeding with the configuration. One of
the checks is to determine the status of the
array’s cache. If the cache battery is still
charging, the cache status check can return
an error and the configure array
command fails. If you set this option to
yes, the configure array command
ignores the error and continues with the
configuration.
no
preferred_server Specifies which of the servers attached to
the array is to be used to configure the
array.
By default, the server chosen to
configure the array is automatically
identified based on the server
number (that is, whether the server
number is odd or even) and the
HBA port number used to connect
to the SFS20 array.
rebuild_priority Specifies the priority that is to be given to
an array rebuild operation in relation to
input/output operations. This parameter is
used when an array is being rebuilt (for
example, after a disk fails or a disk is
replaced).
By default, this option is set to
high.
surface_scan_delay Specifies the length of time the array must
be idle before a surface scan starts.
By default, the delay is set to two
seconds; HP recommends that you
do not change the default unless
you are requested to do so by your
HP Customer Support
representative.
