emx_linkup_timedout: link up timeout has expired

[Andrew S. Chipalyuk]

I have used Unix Tru64 on AlphServer and SAN on CISCO.
After reload the AlphServer one of a fibre chanal adapters changed "LINK STATE" in "down" (hwmgr show fibre).
The SAN function properly.
What is problems?
How i can change link state of fibre adapter?

>>> The SAN function properly.

How many HBAs do you have on the server? Can you post the output of:

emxmgr -t emx

If you see LINK STATE down, then you should check your:

Cable
SAN Switch port
HBA topology configuration

You can switch/interchange/swap these connections to diagnose the problem.

Please, don't forget to assign points to the answers you get. For information about this see:

I have 2 HBA on the server: emx0 and emx3.

>>Can you post the output of:
>>emxmgr -t emx

emx0 state information:
Link : connection is UP
Point to Point
Fabric attached
FC DID 0x250900
Link is SCSI bus 2 (e.g. scsi2)
SCSI target id -1
portname is 1000-0000-C935-D9BE
nodename is 2000-0000-C935-D9BE
N_Port at FC DID 0x250000 - SCSI tgt id 0 :
portname 5000-1FE1-500B-0F79
nodename 5000-1FE1-500B-0F70
Present, Logged in, FCP Target, FCP Logged in,
...
...
emx3 state information:
Link : connection is DOWN
Link is SCSI bus 6 (e.g. scsi6)
SCSI target id -1
portname is 1000-0000-C935-D996
nodename is 2000-0000-C935-D996
There are no connected N_Ports in the topology

>>you should check your:

Yes, i already checked cable and switch port.
May be problem in HBA?

The CISCO Switch shows the emulex 1000-0000-C935-D996 not in fabric.

Have you power cycled the system. Under some circumstances, the adapter will shut off its port and it can only be turned back on with a real/full power cycle. Its rare, but has occurred.

Have you tried swapping cables between emx0 and emx3 at the hba? at the switch? Did the problem stay with the adapter or follow the cable/switch port? If it stayed, then its likely the adapter.. if it moved then its likely the switch port/cable.
