HIDDEN-The driver hides the new logical volume from the OS. VISIBLE-The new logical volume is visible immediately to the OS. Logical Drive category The Logical Drive category has the following options: • ArrayAccelerator (on page 83) • LogicalDrive (on page 83) • NumberOfParityGroups (on page 83) • PreferredPath (on page 84) • RAID (on page 84) • Renumber (on page 84) • Repeat (on page 85) • ResourceVolumeOwner (on page 85) • Sectors (on page 85) • ShrinkSize (on page 85) • Size (on page 85) • SizeBlocks (on page 86) • StripeSize (on page 86) • StripSize (on page 86) ArrayAccelerator This option specifies whether the array accelerator is enabled or disabled for the specified logical drive. The default value is Enabled. LogicalDrive The value that you enter for this option specifies the ID number of the logical drive that is to be created or modified. The first logical drive on an array must have an ID of 1 (not 0), and logical drive numbering must be contiguous. • In Configure action mode, ACU accepts only the ID number of the next possible logical drive. • In Reconfigure action mode, ACU also accepts the ID number of any existing logical drive. NumberOfParityGroups When you create a RAID 50 or RAID 60 configuration, you must also set the number of parity groups. You can use any integer value greater than 1 for this setting, with the restriction that the total number of physical drives in the array must be exactly divisible by the number of parity groups. The maximum number of parity groups possible for a particular number of physical drives is the total number of drives divided by the minimum number of drives necessary for that RAID level (three for RAID 50, four for RAID 60).

HIDDEN
—The driver hides the new logical volume from the OS.

—The new logical volume is visible immediately to the OS.

ArrayAccelerator
This option specifies whether the array accelerator is enabled or disabled for the specified logical drive. The
default value is Enabled.
LogicalDrive
The value that you enter for this option specifies the ID number of the logical drive that is to be created or
modified. The first logical drive on an array must have an ID of 1 (not 0), and logical drive numbering must
be contiguous.
•
In Configure action mode, ACU accepts only the ID number of the next possible logical drive.
•
In Reconfigure action mode, ACU also accepts the ID number of any existing logical drive.
NumberOfParityGroups
When you create a RAID 50 or RAID 60 configuration, you must also set the number of parity groups.
You can use any integer value greater than 1 for this setting, with the restriction that the total number of
physical drives in the array must be exactly divisible by the number of parity groups.
The maximum number of parity groups possible for a particular number of physical drives is the total number
of drives divided by the minimum number of drives necessary for that RAID level (three for RAID 50, four for
RAID 60).
