EMS / FC Adapter error messages

[Charles McCary]

Group, I believe that I'm having EMS problems, but wanted to see if anyone else out there has experienced the following two scenarios:

1) Under intense disk i/o (glance shows 100% disk utilization). I receive and EMS event complaining that:
"Adapter at hardware path 1/12/0/0 : Fibre Channel Driver has been taken
offline due to user request"

2) At another time, after rebooting the box, I receive the following EMS event:
"Summary:
Adapter at hardware path 1/12/0/0 : Target WWN no longer acceptable "

In both cases, by the time I can type in the fcmsutil command to check things out, it reports no problems.

Any ideas?

I haven't seen that error before, but i would suspect a hardware problem with the FC card. Time to call HP.

Look for the event number of the message and check the actions on http://docs.hp.com/hpux/onlinedocs/diag/ems/dm_TL_adapter.htm

For event 26 I recommend to install Fibre Channel driver B.11.00.05 or later (from http://software.hp.com).

Do you have the latest Fibre Channel Patches ?

[Charles McCary]

Louis,

I believe so - which are you referring to specifically?

I used to get many of these messages from variuos servers. Updating EMS and the GPC firware has eliminated them.

Mike,

what firmware are you currently at?

My N4000s and L2000s are at GPC firmware level A.01.09. My EMS is at 3.10 (although some of the sub-catagories say 3.20). The EMS I think was more instrumental in eliminating the problems. However, the new EMS had new support for Superdome and my servers started reporting a couple of problems that only exist on Superdomes (like fans not working). So I had to edit the table of error messages and change it so EMS wouldn't report the false Superdome errors. After all that it is pretty quite now.

Mike,

Hey - hate to ask, but how did you come up with what firmware you're at?

tx,

Charlie

Get into your Service Processor by hitting CTRL-B from the console and type in HE for help. The firmware should be printed at the top of the menu.

I had a simular problem, I kept seeing my VG's
drop off and re-join the system. What it came down to it, in my case was that the GLM's on the fiber cards were recalled from HP. If your cards are a little older, you may want to check that option out.

Hi,

Is this machine connected directly to the Mass storage device (EMC or XP256 or XP512) or is the fibre connection going to through a FC hub. I have seen this problem occur mostly on the older cards FC cards and in my case the problem seems to have been solved upon replacing the card. I don't have the card numbers handy but I could send it to you tomorrow if there is a need.
