This counter tracks how many SCSI 'Reservation Conflict' statuses were received on this flow, meaning the initiator tried to access a LUN that was reserved (locked) by another host, typically in a clustered storage environment using SCSI reservations for exclusive access arbitration. An admin seeing this climb on a flow tied to a clustered application should check for a misbehaving cluster node holding a stale reservation, or a genuine, expected contention pattern from cluster failover testing. A sudden burst of reservation conflicts right after a cluster failover event would be the expected, benign explanation, while a steady ongoing trickle would suggest a stuck reservation needing manual clearing.
