Cybernetics UM-MV-86-B1-0801
In addition, if there is a unit with the status Inoperable before a rescan (for example, a
RAID 5 unit missing two or more drives), and a rescan finds drives that complete the unit,
the inoperable unit will become a valid unit.
Unit Maintenance
The Unit Maintenance section of the page lists all existing units on the current controller,
and displays summary information about them.
The top row shows information about the unit, while subsequent rows show summary
information about each drive in the unit.
Unit Information
Unit Number: The unit number assigned to the unit by the firmware.
# Drives: Number of drives in the unit.
Type of Unit: Type of unit specified during configuration: RAID 0, RAID 1, RAID 5,
RAID 10, RAID 50, Single Disk, Spare, or JBOD.
Capacity: The usable capacity (size) of the unit.
Status: Operational status of the unit: Ok, Rebuilding, Initializing, Verifying,
Degraded, or Inoperable (missing drives). When Rebuilding, Initializing, or Verifying,
the percentage (%) complete is also shown. The % complete can be active or
paused. To see whether this task is currently active or paused, click on the unit
number to display the Unit Information page, which has that information.
Drive Information
Port: The port to which the drive is connected.
Model: The model of the drive.
Capacity: The capacity (size) of the drive.
Status: The status of the drive: OK, Not Supported, Not Present, and so forth. If you
need help regarding a status displayed here, please contact Technical Support.
Remove Drive: The Remove Drive link removes a drive from the controller so that
you can safely unplug it. In the Unit Maintenance section, this link is only provided for
drives that can be safely removed without creating an inoperable unit. (For example, a
RAID 5 missing two or more drives or a RAID 0 missing one or more drives would
become inoperable.) If you remove a drive from a redundant unit, the unit will become
degraded. Once a unit has become degraded, additional drives cannot be removed
without making it inoperable, so no Remove Drive link will display.
Caution
Removing or adding drives which are not in hotswap carriers can result
in a system hang or may even damage the system and the drive.
