Fibre Card query

[Paul Thomson_2]

On a system, the fibre card did not seem to fully initiliase earlier after a reboot at the weekend.
# fcmsutil /dev/fcms2 | more

Local N_Port_ID is = 0x000000
N_Port Node World Wide Name = 0x10000060B0C0D4FF
N_Port Port World Wide Name = 0x10000060B0C0D4FF
Topology = UNKNOWN
Speed = 1062500000 (bps)
HPA of card = 0xFFB08000
EIM of card = 0xFFFA200C
Driver state = LOOPBACK_STATE
Number of EDB's in use = 0
Number of OIB's in use = 0
Number of Active Outbound Exchanges = 0
Number of Active Login Sessions = 0
Once the card has been disabled and re enabled the device started to work and all the disks on the device were see OK, Ioscan for the card shows....

lan 2 10/8.5 fcT1_cntl CLAIMED INTERFACE HP Fibre
Channel Mass Storage Cntl
/dev/fcms2

Is there any further settings to check on the card / patching which I may do / or anyone knows of ?

On the other end of the fibre is a Hitachi SAN.

Your HBA, or fibre channel adapter, (* same thing *) only auto sense information from either the switch or the peripheral device. So right now with your 'Topology = UNKNOWN', nothing is going on.

One of our cards show

Also note that the device should show 'CLAIMED' in ioscan. Use:

ioscan -fnkC fc

Old chestnut here , but .....

Are you upto date on patches ?

http://www5.itrc.hp.com/service/cki/patchDocDisplay.do?patchId=PHKL_28004

Host system panics due to the topology
toggling. The FCMS Driver is
trying to come up in a Loop topology
and the Host system is trying to come up
in a point-to-point topology.

Hi all,

After disabling / re enabling the card it shows....
gb898_m:/# fcmsutil /dev/fcms2

Local N_Port_ID is = 0x000001
N_Port Node World Wide Name = 0x10000060B0C0D4FF
N_Port Port World Wide Name = 0x10000060B0C0D4FF
Topology = IN_LOOP
Speed = 1062500000 (bps)
HPA of card = 0xFFB08000
EIM of card = 0xFFFA200C
Driver state = READY
Number of EDB's in use = 0
Number of OIB's in use = 0
Number of Active Outbound Exchanges = 1
Number of Active Login Sessions = 3

The card also shows CLAIMED in ioscan. Still checking patching out, I am 100% sure we are way out of date !!!

[Paul Thomson_2]

Current software is
J3630BA B.10.20.61 Fibre Channel Mass Storag
e Driver

PHSS_23581 B.10.00.00.AA Fibre Channel Mass Storage Driver Patch

I believe this is the most upto date for what we have....

[Michael Steele_2]

Since your driver state is ready and your topology is now displayed and your 'Local N_Port_ID' as well, you???re good to go.

Note your 'Local N_port_ID' = 1 and try this:

fcmsutil /dev/td1 echo -l 1 200 5

(* Send 5 echo packets of 200 bytes each to a remote N_Port with loop_id 1 *)

Check further HBA info by referring to 'loss of signal and Bad Tx Char' and transmission counts via:

fcmsutil /dev/td0 state
fcmsutil /dev/td1 state
fcmsutil /dev/td? state, etc.

Report back with any problems.
