HBA failover
Sansurfer shows all other luns failed over to the alternate path and then failed back to the preffered path when the link came back except for the lun to which the data was being written to. That still shows as using alternate and is not failing back. Is there anything that needs to be done to force this? Reboot? Or is there any there command to do this?

Re: HBA failover
Could you unplug port2 and check if it is fail over to port1.If this functions well, you are safe interms of data integrity.

Re: HBA failover
No need to reboot server. since your file transfer continuing on port2, it won't fail back to port1 even if connect port1 back. But if you want to test it then during file transfer, unplug port2 and see if it fails back to port1.
