va7410 on HPUX 11.31 Error: Cannot open target. Please retry after discovery process.

[Jamie Willard_2]

All,
I have come across an interesting problem and I could use some assistance. I have an rx8620 server running HPUX 11.31. This server is unable to reliably communicate with a va7410 (or any VA) through â armâ commands. Some commands work, some do not. Armdiscover always works. So does armdsp -i, armdsp -t, armdsp -f, and a few others.

root@rich:/> armdiscover
This could take several minutes ...

Does anyone have any ideas for this? I have already attempted the following:

Recreate DeviceDBFile:
/opt/sanmgr/commandview/client/sbin/HA_Dial_Stop
mv /var/opt/sanmgr/commandview/server/data/DeviceDBFile /tmp
/opt/sanmgr/commandview/client/sbin/HA_Dial_Start
armdiscover

Bump max_thread_proc and nkthread to obscene values and used kcusage to view:
max_thread_proc 129 / 10000
nkthread 1021 / 29000

Replace va7110 array with a va7410 array that works on another system.
Modified access.dat
Modified commIPAddr.txt
Uninstalling and reinstalling Commandview 1.09.03
Rebooting

Any help is appreciated, I feel like I'm spinning my wheels. I have included an ioscan and a swlist. The only other thing I notice is multiple versions of Java installed.

Hi,

Does armdiag -I(UC i) -if file_name array_id work?

Can you attach tddiag /dev/fcd2 > file_name.log results?

Rgds,

Thanks for the reply, here is the tddiag output for fcd2.

and the armdiag -I output as well.

Well this isn't fun...

Get /dev/fcd2 device info
+ tdutil /dev/fcd2
1 ERROR: The installed driver and tdutil are not compatible

++ Get /dev/fcd2 device vpd info
+ tdutil /dev/fcd2 vpd
1 ERROR: The installed driver and tdutil are not compatible



Let's try the fcddiag command that I should have posted the first time...

# fcddiag /dev/fcd2 > file_name.log

Apologies all around.


Rgds,

[Jamie Willard_2]

I should have caught that myself. der.. Sorry.

Have you though about updating the firmware on these cards. The release notes have some link and re-scan fixes that may or may not pertain to your issue, but it might be worth a try:

(Still looking at the files but wanted to throw this out there)

Rgds,

[Jamie Willard_2]

Very nice. I will update them.

Jamie,

FYI:
...
127 Retry on private loop device exhausted 1364
...
130 PLOGI error during private loop scan 4092
...

This might be why it's timing out during the scans?

Also take a look at your event.log and see if there are any other indications there:

/var/opt/resmon/log/event.log


You might also want to run logtool...

There are some other errors in the fcddiag results you may want to investigate. Anyway updating the firmware might be worth a shot.


Rgds,

If you find any of this useful, points always welcomed ;-)

Jamie,

Looking through the VA logs appears to indicate some name resolution issues with the agents.
