Symptoms

An HBA or storage device automatically configures as a loopback port on a Connectrix B-Series switch.

 

Cause

This could be caused by the controller configuration on the HBA or storage device.

 

Resolution

Check whether the end device is configured for Fibre Channel Arbitrated Loop (FC-AL). Also check the integrity of the SFP and cable. Then reset the port as follows:

  • portcfgpersistentdisable
  • portcfgdefault
  • portcfgpersistentenable

If the status of the port is still loopback after performing the above, move the cable to a free port. If the issue follows the cable, it is likely an issue with the connected device. Further troubleshooting must be performed at that end.
