ciscoScsiFlowRdFailedIos
Module: CISCO-SCSI-FLOW-MIB
OID (symbolic): CISCO-SCSI-FLOW-MIB::ciscoScsiFlowRdFailedIos
OID (numeric): 1.3.6.1.4.1.9.9.447.1.2.1.1.3
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: The total number of SCSI read operations that have failed on this LUN on this flow.
What is ciscoScsiFlowRdFailedIos?
This counter tracks how many of the SCSI read operations on this LUN/flow actually failed, rather than completing successfully. An admin comparing this to the total in ciscoScsiFlowRdIos calculates a failure rate for this specific path, and a rising failure count isolated to one flow - while others on the same switch stay clean - points to a problem specific to that host-array-LUN combination rather than a fabric-wide issue. A flow showing 200 failed reads out of 50,000 total would already be a red flag worth escalating to the storage team.
