Module: CISCO-SCSI-MIB
OID (symbolic): CISCO-SCSI-MIB::ciscoScsiLuOutQueueFullStatus
OID (numeric): 1.3.6.1.4.1.9.10.95.1.5.1.1.14
Node type: OBJECT-TYPE

Description: This object represents the number of queue full statuses received by this logical unit.
What is ciscoScsiLuOutQueueFullStatus?
This counter tracks how many times this specific logical unit has returned a SCSI QUEUE FULL status to the initiators sending it commands. A rising count on one LUN means that LUN's command queue depth is being overrun by initiators sending I/O faster than it can accept, which shows up to hosts as retried or slow I/O against that particular volume. Seeing this counter climb from 0 to 340 during a backup job points to that LUN's queue depth being too shallow for the number of concurrent backup streams hitting it.
