Go to SolutionXtremIO: FC Error Link Failure
When I run this command in every XIO, it always shows parameter Link-Failure count =1. What does it imply? What issue can cause what error for these parameters? A brief note would be great. Thanks.
xmcli (idigit)> show-targets-fc-error-counters
Name Index Cluster-Name Index Dumped-Frames Sync-Loss Signal-Loss Invalid-Crc Link-Failure Prim-Seq
X1-SC1-fc1 1 XIO 1 0 0 0 0 1 0
X1-SC1-fc2 2 XIO 1 0 0 0 0 1 0
X1-SC2-fc1 5 XIO 1 0 0 0 0 1 0
X1-SC2-fc2 6 XIO 1 0 0 0 0 1 0
It shows that historically there was a failure that caused the link to go down. With it only being 1 and on all of the links I wouldn't worry. If it was a high number it could indicate a flapping port. One thing to keep in mind also is that it is a historic value so it could be very old.
there is no current way to clear these counters from CLI. As far as I am aware the only way to clear the counters would be via a reboot of the relevant SCs but wouldn't advise this as it is unneccesary seeing as there is no indication of a current link problem and is likely present since cluster initialization time as houdem already stated...hope this helps.

Hello iDigIT,
Adding onto what ChrisPy noted - When the cluster is first created, it is expected that a single link failure would be accrued during the initialization process.
A single instance of link failure should not be indicative of any port or SAN issues.
