RAID Disk Specifies whether the disk is part of a RAID array (Yes or No). This
field is grayed out under the following conditions:
• The disk does not meet the minimum requirements for use in a
RAID array.
• The disk is not large enough to mirror existing data on the
primary drive.
• This disk has been selected as the Hot Spare for the RAID array.
Hot Spr Specifies whether the disk is the Hot Spare for a RAID array (Yes or
No). RAID arrays are not required to have a Hot Spare. Only one
Hot Spare per RAID array is permitted. You can define a Hot Spare
when you create an array or at any time after creation, if the array is
made up of two disks or fewer. This field is grayed out under the
following conditions:
• The disk does not meet the minimum requirements for use in a
RAID array.
• The array already has a Hot Spare.
• The array is made up of the maximum number of disks (three).
• The disk is not large enough to mirror existing data on the
primary disk.
• Integrated Striping firmware is used. (Striped arrays do not
support Hot Spares.)
