Teresa,

This parameter refers to support for native fibre channel tape devices 
specifically, although it was recommended to me by QLogic support for SCSI 
drives connected through routers/gateways too.  QLogic's argument was that 
FC-Tape Support enabled their HBA to handle tape errors at FC-2 level.  FC-2 is 
one of the lower layers in the fibre channel protocol roughly equivalent to the 
internet layer in the TCP/IP stack.

Subject: [Networker] ADIC Scalar 10K and Windows storage node


Hi all,



I'm working through the configuration of a Solaris NW server, Windows
storage node and an ADIC Scalar 10K.  All of the above are connected via
a SAN.  The tape drives on the Sc 10K connect to an SNC5100 and then the
SNC's are connected to the SAN.  The Solaris server is connected to the
SAN via Emulex HBAs and the Windows storage node is connected via QLOGIC
HBAs.



In reading through the documentation for the QLOGIC HBAs (QLA2202F-CK) I
came upon the following:





*   FCTape



    To configure the driver to support FC tape, please use the

    following procedure:



    1. Click on "Start", select "Run", and open the REGEDT32 program.

    2. Select HKEY_LOCAL_MACHINE and follow the tree structure down to

       the QLogic driver as follows:



            HKEY_LOCAL_MACHINE

              SYSTEM

                CurrentControlSet

                  Services

                    Ql2200

                      Parameters

                        Device



    3. Double click on



           DriverParameters:REG_SZ:MSCS=2;UseSameNN=1



    4. If the string "FCTape=" does not exist, append to end of string



           ;FCTape=1



    5. If the string "FCTape=0" exists, change the value from 0 to 1.



    6. Click OK.



    7. Exit the Registry Editor, then shutdown and reboot the system.





Is anyone familiar with this setting?  I'm curious about what exactly
this entry does.  The documentation only says how to set it, but doesn't
say anything about its purpose.



Thanks.

Teresa
