CURRENT MONITOR DATA:

Event Time……….: Thu Jul 23 11:33:07 2009
Severity…………: SERIOUS
Monitor………….: dm_TL_adapter
Event #………….: 23
System…………..: hp-ux

Summary:
Adapter at hardware path 0/2/1/0 : Fibre Channel driver has gone into
non-participating mode
Description of Error:
lbolt value: 3207

The Fibre Channel Driver has gone into non-participating mode
Frame Manager Status Register =  0x200002ff
Probable Cause / Recommended Action:

A cable or hardware problem exists. This can also be caused due
to the Tachyon TL adapter changing its AL_PA across a LIP.
Do the following:
1. Verify that the fiber optic cable is functional and securely
attached to the Fibre Channel Mass Storage Adapter.
2. After checking the cabling, execute a loopback test using
fcmsutil.
Command syntax is as follows:
/opt/fcms/bin/fcmsutil <device_file> lb plm
If the problem persists after verifying fiber optic cabling,
replace the adapter

Checking the device file.

root@hp-ux:/ # ioscan -fnC fc
Class     I  H/W Path  Driver S/W State   H/W Type     Description
=================================================================
fc        0  0/2/1/0   td   CLAIMED     INTERFACE    HP Tachyon XL2 Fibre Channel Mass Storage Adapter
/dev/td0
fc        1  0/6/1/0   td   CLAIMED     INTERFACE    HP Tachyon XL2 Fibre Channel Mass Storage Adapter
/dev/td1

I tried to pass td1 as argument but it needed the full path.

root@hp-ux:/ # /opt/fcms/bin/fcmsutil td1 lb plm
Error: FCP driver not loaded.

I passed the entire path and the fcmsutil worked:

root@hp-ux:/ # /opt/fcms/bin/fcmsutil /dev/td0 lb plm

WARNING: This is a DESTRUCTIVE test.
This might result in failure of current I/O requests.
