SCSI Sense commands

I just can't figure this one out.
The ESX hosts we have in the environment are reporting issues with connectivity to the storage fabric.  They connect fine and push data back and forth but one server in particular reports that it keeps losing connectivity to one of the paths through powerpath.  Then it fixes itself.

With the vkernel log it shows SCSI Sense Codes and points to Destination then the Host and back and forth.   When I get the time this has to be resolved.
