ciscoScsiLuStatus
Module: CISCO-SCSI-MIB
OID (symbolic): CISCO-SCSI-MIB::ciscoScsiLuStatus
OID (numeric): 1.3.6.1.4.1.9.10.95.1.5.1.1.8
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The status of this logical unit: - unknown(1): The status of this logical unit cannot be determined. - available(2): The logical unit is fully operational (i.e., accepts media access SCSI commands and has no state information to report). - notAvailable(3): The logical unit is capable of being supported but not available (i.e., no logical unit is currently present or the logical unit is present but not configured for use). - broken(4): The logical unit has failed and cannot respond to SCSI commands. - readying(5): The logical unit is being initialized and access is temporarily limited. - abnormal(6): The logical unit has state information available that indicates it is operating with limits. The ciscoScsiLuState indicates what those limits are.
What is ciscoScsiLuStatus?
This object is the enumerated operational status of the logical unit, one of unknown, available, notAvailable, broken, readying, or abnormal, exactly as spelled out in the object's own description. This is the single field to poll to catch a LUN going from available to broken, since on a SAN that transition means every initiator mapped to it is about to start seeing I/O errors. Seeing ciscoScsiLuStatus flip from available(2) to broken(4) overnight would explain a subsequent wave of application-level disk errors reported by the hosts that use that LUN.
