We have SAN storage and have 2 paths. One of the path is failing most of the time. What may be the problem. Do you think problem with GBIC module? What would you recommend to fix or troubleshoot?
It could be any number of failures - bad HBA, cable, GBIC/SFP, I/O Module, switch port, switch....I would go about it by process of elimination. It might help if you can describe the hardware brands/models you are using
