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

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?

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

and the armdiag -I output as well.

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

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.

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)

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.

HostBootEvent failure: MANAGEMENT_SERVER_UID value not set.

I have confirmed this error is occurring on a working system.

I have also reproduced this problem on two 11.31 hosts now, rp7420 and the original problem rx7620. Has anyone seen this?

That's two different servers with two different va7410's. I also have a va7110 that does the same thing on both of these servers.

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

I have, thank you. I tried an experiment. I re-installed the OS on the machine to 11.31 IA again. This time I used disks from February of 2007. Installed commandview 1.9.3. The array works. I have patched the system up to March 2008 and it still works.

I know that when I install from my September 2009 CD's it doesn't work. Not even when I patch the system up to March 2010.

I am going to install patches from March 2009 next and see what happens. Then March 2010.

Right now it appears that HP broke compatibility sometime in 2008 or 2009. SPOCK still says it should work.

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

I wonder if this has to do with different JAVA versions being installed?


It seems you're on to the resolution!

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

Here is the swlist from the working OS. It has two different versions of Java.

On the original problem machine we are swapping the array with an MSA. I am continuing to test on the rp7420 w/VA7410 to prove if it is something I can fix or if it will require HP to patch.

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

Interesting...

The Java Versions are definitely different between the two systems. The working one has the "qualified" versions as stated in the support document, whereas the problem one originally lists newer 1.4 and 1.5 versions (and includes Java6).
