I was trying to see if I could duplicate the problem from my end and was not able too - I have the same Qlogic HBA's "ISP2432-based 4Gb Fibre Channel to PCI Express HBA (rev 03)" with version 2956. On the Target I have set to use 32bit single and SMP with TESTING (kernel 2.6.23) also I did a direct connection between the 2 DSS and still was able to connect them both. Both HBA's are at configuration defaults and the only system reboot was the Target system after setting as Target in: SETUP -> Fibre Channel -> Function: QLOGIC Target. So everything was configured from defaults.
