■ Critical – Either the virtual disk is being initialized or reconstructed; or, one
drive is down or missing in a RAID 1, 3, 5, 10, or 50 virtual disk; or, two
drives are down in a RAID 6 virtual disk.
■ Offline – The virtual disk has an unrecoverable error, and data is lost.
■ Quarantined – One or more drives in the virtual disk were not detected after a
restart or rescan. A virtual disk can become quarantined if drives are removed,
their enclosures are not powered on, or their enclosures are slow to power on.
The virtual disk has been frozen until the drives are added back into the
system or until the virtual disk is manually removed from quarantine.
■ Number Of Drives – For RAID 1, 3, 5, 6, 10, or 50, the number of drives in the
virtual disk when fault tolerant. For example, if a three-drive RAID 5 virtual disk
loses a drive, this value remains 3. For Non-RAID or RAID 0, the number of
drives in the virtual disk.
■ Spare Drives – Number of spares assigned to this virtual disk.
■ Number Of Volumes – Number of volumes in the virtual disk.
■ Virtual Disk Serial Number – Unique number assigned by the owning controller.
■ Preferred Owner – Controller that owns the virtual disk during normal operation.
■ Current Owner – Either the preferred owner during normal operation or the
partner controller when the preferred owner is offline.
■ Chunk Size – Amount of contiguous data in Kbyte that is written to a virtual disk
member before moving to the next member of the virtual disk.
■ Date Created – Date when the virtual disk was created.
■ Utility – Name of any utility running on the virtual disk, or None.
The Enclosure View panel shows a graphical representation of disk drives by
enclosure. On this page only, drives in any virtual disk except the selected one are
gray. For more information, see “Disk Drives by Enclosure” on page 156. If this
panel does not display, see “Enclosure View is Unavailable” on page 157.
