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
