fcmsutil comes back fine, and the LED on the HBA is fine, but why not the LED on the switch?
First time posting here, so I don't know what everyone needs to help to find a solution, but I will try to provide as much as possible.
The system is running 11i, with a Tachyon 2XL card. The driver came with the system, and I've download the necessary patch for the HBA (Don't remember the exact number, but I believe it was 27***, preceding the 23696 patch). Anyway, after everything is properly installed, configured, and zoned (three switches; the server is on one, three linux boxes on the second one, and the HP-UX box on the third. All five are put into one zone), the server could not detect the WWPN from the HP-UX box.
Here are what I have at the moment:
The lights on the HBA are on, one green, one yellow/amber, so I know it's fine.
The port light on switch three, which is where my HP-UX box is connected to, is NOT on. I've checked the GBIC, tried different cables, and rebooted the switch, all to no avail.
When I run "ioscan -funC fc", I get the following:
Class I H/W Path Driver S/W State H/W Type Description
=================================================================
fc 1 10/6/7/0 td CLAIMED INTERFACE HP Tachyon TL/TS Fibre Channel Mass Storage Adapter
/dev/td1
As you can see, /dev/td1 is claimed.
Now, when I run "fcmsutil /dev/td1", I get the following:
Vendor ID is = 0x00103C
Device ID is = 0x001028
PCI Sub-system Vendor ID is = 0x00103C
PCI Sub-system ID is = 0x000006
Topology = IN_LOOP
Local N_Port_id is = 0x000001
Local Loop_id is = 125
N_Port Node World Wide Name = 0x50060B000007AD5B
N_Port Port World Wide Name = 0x50060B000007AD5A
Driver state = ONLINE
Hardware Path is = 10/6/7/0
Number of Assisted IOs = 0
Number of Active Login Sessions = 0
The driver state is ONLINE, so it seems fine to me...
Lastly, here is what I get for running "fcmsutil /dev/td1 stat":

It seems most of the outputs indicate normalcy, but "FCP assists freeze failure 7"? Any suggestions would be much appreciated.
Thank you,

You might find additional low-level errors e.g. concerning FL_PORT or F_PORT login via mstm -> run -> logtool
Also You can check if the HP-UX box 'sees' anything like in the following:
root@lala:/tmp>/opt/fcms/bin/fcmsutil /dev/td0 get remote all
Target N_Port_id is = 0x[...]
Target state = DVS_READY
Symbolic Name = EMC SYMMETRIX xxxx
Port Type = N_PORT
Target Port World Wide Name = 0x[...]
Target Node World Wide Name = 0x[...]

These look suspicoius;y like signals are being lost!!! If you are getting green lights on Host I'm guessijng the port may be the problem, try using another port?

It sounds like the other ports were disabled...

Re: fcmsutil comes back fine, and the LED on the HBA is fine, but why not the LED on the switch?
also, You wrote the last switch had no zoning capability - so the others had? I'd then think You're running a fabric configuration?
If Yes, the HBA didn't properly login according to the Topology = IN_LOOP fcmsutil stated.
please do check the EMS logs via logtool.
