This Gauge32 is the retry count of the current attempt of the finite-state-machine workflow running against this internal backplane link. It matters on the internal Ethernet link that carries a blade's traffic from the chassis I/O Module up to a Fabric Interconnect over the backplane because UCS Manager automatically retries certain failed steps a limited number of times, and a high retry count without success is what tells an admin automatic recovery has been exhausted. An fsmTry value of 5 or more on this backplane link without the workflow completing is the point at which an admin would intervene manually rather than continue waiting for auto-retry.
