Up to a 15-digit number including the "." (decimal point) can be input. Note that when "MB" is

selected, the specified value is converted to "MB" and rounded down to the nearest whole number.

Volume Information
Use all Largest Free Space
Select the "Enable" checkbox to create the specified number of WSVs with the largest available free
space in the selected RAID group.
WSVs are created by concatenating spaces with the same capacity in multiple RAID groups. If
"Enable" is selected, the specified number of WSVs in the "Number of Volumes" field are created
using the smallest "Largest Free Space" value in the concatenated RAID groups.
Up to 15 numbers can be used. If a decimal point is included in the input value, up to 14 numbers
can be used.
[Example] 0.1234567890123 (14 numbers and a decimal point)
When creating multiple volumes in a RAID group, the maximum number of volumes that can be
created for the user capacity may be reduced. To use the entire user capacity, the volume size must
be an exact multiple of the basic size (stripe size). Refer to "E.1 Basic Size for each RAID Group"
(page 995) for details.
When "Wide Striping Volume" is specified for "Type", "Manual" is selected automatically. Note that
"Automatic" cannot be selected.
When "Enable" is selected, the capacity and the unit that are specified for "New Volume" are
not available.
The capacity for created WSVs is not displayed. Use the [Volume] screen to check the volume
capacity after volume creation is complete.
