Virtual Array VA7400 not recognized on HP-UX

We have a VA7400 virtual array directly connected to an HP9000/N400/55 with HP-UX 11.23. I installed SDM 1.09. The drives are located when running armdiscover, but noty the array. The 15 disk drives are also visible in ioscan but not the array.
I restarted HADial but the result is the same.
I'm not able to connect through the serial interface because I work from remote.
Is there any way to see the hardware config of the disk array because I suspect that we are having only interface cards and not controller cards installed?

Thanks

Re: Virtual Array VA7400 not recognized on HP-UX

Hi,

Was this a working setup? Did you get the issue after installing SDM?

What is the error getting while running armdiscover?

Did you try the below procedure?

# uname -a
Take note of the hostname.
# /etc/hosts
Make sure IP <---> HOSTNAME entry is good.
# /etc/nsswitch.conf
Make sure nsswitch.conf is using /etc/hosts as its first option, with or without DNS.
# nslookup HOSTNAME
# nslookup IP_ADDRESS
Make sure that name resolution is good for both the HOSTNAME and IP_ADDRESS.
# cat /opt/sanmgr/hostagent/config/commIpAddr.txt
NOTE: If any changes are made in any of the steps above, issue the command armdisp -ia may return a No devices found error unless CommandView is restarted.
Perform the following steps to restart CommandView and the Monitor:
Restart CommandView:
# HA_Dial_Stop
# HA_Dial_Start
Restart Monitor:
# /opt/sanmgr/hostagent/sbin/HA_trigger stop
# /opt/sanmgr/hostagent/sbin/dial_trigger stop
# /opt/sanmgr/hostagent/sbin/HA_trigger start
# /opt/sanmgr/hostagent/sbin/dial_trigger start
Check VA discovery
# armdiscover
The armdsp command should now run as expected.
# armdsp -i

Re: Virtual Array VA7400 not recognized on HP-UX

Hi Viveki,
The story is that this is a new installation of a server and a va7400 array.
The connexion works fine between the server and the array but only the disks were presenting to the server and not the array.
I could run the armdiscoover succesfuly before but with the same result as in the attached armdiscover.txt file.
I did
# /opt/sanmgr/hostagent/sbin/HA_trigger stop
# /opt/sanmgr/hostagent/sbin/dial_trigger stop
renamed the DeviceDBFile then
# /opt/sanmgr/hostagent/sbin/HA_trigger start
# /opt/sanmgr/hostagent/sbin/dial_trigger start
then
# armdiscover -v

but the result is the same as the first time.

In the attached ioscan.txt you could see also that there was no array discovered.
I added also the dsp results from VFP.

Thank for your help

Re: Virtual Array VA7400 not recognized on HP-UX

The previuos messages contained a file that was originally named array.txt.
I noticed that I could only attach one file so I'm adding the screen dump containing the ioscan and armdscover in the present one.

Re: Virtual Array VA7400 not recognized on HP-UX

Can you post a

# ioscan -fn

after you created the LUN0 and run insf -e?

Commandview needs this LUN0, otherwise it cannot see the array.





Hope this helps!
Regards
Torsten.

Re: Virtual Array VA7400 not recognized on HP-UX

Of course, Torsten

I attached the file containing the output of both insf -e and ioscan -fn.

Thanks

Re: Virtual Array VA7400 not recognized on HP-UX

This is very strange, because normally you never see disks in ioscan, only LUNs.

You say you are remote - sure the VA is connected? Not only a DS2405? But even then this should be visible ...

Hope this helps!
Regards
Torsten.

Re: Virtual Array VA7400 not recognized on HP-UX

I thought that too.
Would it be because the fiber is connected to the DISK FC and not on HOST FC like it is on my others servers that are working?

Re: Virtual Array VA7400 not recognized on HP-UX

hi,

I think you need to get someone to physically check what you have, and what is connected.

from the back they might look similar, and someone has got it wrong

it seems very likely you do not have a VA array, or certainly not connected. I think you are just connected straight into a DS2405 disk system. When direct connected in jbod mode, you would see the disks like you do in your ioscan.

Also, do you really have that many dvdrom drives? if you do fine, if you dont then you have a scsi ID conflict error, on that bus

Re: Virtual Array VA7400 not recognized on HP-UX

I'm sure that it's a va7400 and not a DS2405 because I thought the same until I could see the box with my own eyes.
The only thing that seems to be different from the other servers that I have an that are working fine with their va7400 arrays is that on the present case the fiber optics is connected to the DISK FC and not on HOST FC like for the others.
I thought also that probably there are no array controllers but only FC interfaces but I could see by using VFP on the array that the connectors are there.
For the DVDs there are SCSI conflicts for sure as I cannot find the DLT 4000 tape either.
