Using the Command Line Interface
Before you can work with arrays, you must have previously
opened the controller. In addition, you must have initialized your
disk(s) to prepare for array operations.
The minimum size of an array is 10 MB.
Before creating any array, use the disk show space command
to display information about your disks. In the following example,
the Usage column indicates Free for each disk, which means that
the space on each disk consists of available space.
AAC0> disk show space
Executing: disk show space
Scsi C:ID:L Usage Size
----------- ---------- -------------
2:01:0 Free 64.0KB:8.47GB
2:02:0 Free 64.0KB:8.47GB
2:03:0 Free 64.0KB:8.47GB
2:04:0 Free 64.0KB:8.47GB
After creating an array, use the container list command to
display information about the array. In the following example, the
Num Label column indicates the array ID 0 and the array label
Venus. The Type column indicates a Vo lu me set. The Tota l S ize
column indicates that the array is 100 MB.
AAC0> container list
Executing: container list

Creating a Volume Set
To create a volume set, use the container create volume
command. In the following example, the volume set 0 is created on
SCSI device (2,01,0) from 100MB (megabytes) of available space.
The array’s raw cache is enabled, and the label Ven us is specified.
AAC0> container create volume /cache=TRUE /label=Venus
((2,01,0), 100M)
Executing: container create volume /cache=TRUE /
label=Venus ((CHANNEL=2,ID=1,LUN=0),104,857,600)
container 0 created
