DescriptionName
The operational state of the disk drive. This can be the following:
• Operable—The disk drive is operable.
• Inoperable—The disk drive is inoperable, possibly due to a
hardware issue such as bad blocks.
• N/A—The operability of the disk drive cannot be determined.
This could be due to the server or firmware not being support for
disk drive monitoring, or because the server is powered off.
The Operability field may show the incorrect status for several
reasons, such as if the disk is part of a broken RAID set or if
the BIOS POST (Power On Self Test) has not completed.
Note
Operability field
The presence of the disk drive, and whether it can be detected in the
server drive bay, regardless of its operational state. This can be the
following:
• Equipped—A disk drive can be detected in the server drive bay.
• Missing—No disk drive can be detected in the server drive bay.
Presence field
Interpreting the Status of a Monitored Disk Drive
Cisco UCS Manager displays the following properties for each monitored disk drive:
• Operability—The operational state of the disk drive.
• Presence—The presence of the disk drive, and whether it can be detected in the server drive bay, regardless
of its operational state.
You need to look at both properties to determine the status of the monitored disk drive. The following table
shows the likely interpretations of the property values.
InterpretationPresence StatusOperability Status
No fault condition. The disk drive is in the server
and can be used.
