HP PCI Tachyon XL2 Fibre Channel Driver Release Notes
Known Problems and Workarounds
Known Problems and Workarounds
Following is the known problem and workaround in the HP PCI Tachyon TL/TS/XL2 Fibre Channel driver:

Problem: The A6795A Fibre Channel adapter settles in the Public Loop topology as opposed to the Point
to Point Fabric topology when connected to a 4Gb Fibre Channel Brocade Switch port.
Symptom: The /opt/fcms/bin/fcmsutil /dev/ tool displays PUBLIC_LOOP in the output instead of the
expected PTTOPT_FABRIC output, against the Topology field.
The /dev/ is a device file that corresponds to the A6795A Fibre Channel adapter that is connected
to the 4Gb Brocade Switch port.
Workaround: Configure the Brocade switch port that is connected to the A6795A Fibre Channel adapter, as G port.
Use the telnet command to connect to the switch. To enable the G port settings, enter the following command at the
switch prompt:
switch> portcfggport , 1
The following message is displayed at the switch prompt:
Committing configuration...done.
For more information about the portcfggport command, use the help command:
switch> help portcfggport
For detailed information about the portcfggport command, see the manpage and Release Notes for the
Brocade switch present at:
http://www.brocade.com/index.jsp
To turn off the G port settings, enter the following command at the switch prompt:
switch> portcfggport , 0
The following message is displayed at the switch prompt:
Committing configuration...done.
