not seeing LUN

shashi kanth — Fri, 04 Feb 2011 04:56:20 GMT

EVA3000- HSV101 with latest firmware, and 11iv3 IA.

The server is seeing the EVA controllers, but if i assign a LUN, the server is not seeing the LUN.

1) did ioscan several times,and rebooted several, but server is still not seeing the LUN.
2) Zoning is proper on the SAN.
3) LUN masking is correct on CV EVA, with correct WWNs for the host.

Have you tried insf -eC disk to create new device files.

cross check zoning again.

Hi

can you post:
- ioscan -funC disk
- ioscan
- insf -e
- ioscan -funC disk

I can say zoning is proper, thats why the server is seeing the controllers.

Re: not seeing LUN

Duncan Edmonstone — Fri, 04 Feb 2011 07:24:02 GMT

As the devices are reported as HSV101, not HSV100, I'll assume you are on VCS 4.x, not 3.x.

What host type did you select when presenting the LUN - you did make sure it was HP-UX didn't you?

HTH

Duncan

Re: not seeing LUN

Duncan Edmonstone — Fri, 04 Feb 2011 07:29:14 GMT

Also, check the host ports listed under the Host properties for this system on Command View EVA. The ports listed should match what you see as the "N_Port Port World Wide Name N_Port Port World Wide Name" from an fcmsutil output for your FC HBAs.

Re: not seeing LUN

shashi kanth — Fri, 04 Feb 2011 07:38:12 GMT

The OS type set as HP-UX only.

The WWNs which i set are correct. They automatically appeared in CV EVA when i was creating the host in CV EVA.

I am facing this problem not just one host. All the hosts which are connected to this EVA are not seeing the LUNs from this EVA. They are seeing the EVA controller but not seeing the LUN when i assign a LUN to them.

Re: not seeing LUN

Jorge Pons — Fri, 04 Feb 2011 08:17:48 GMT

Hi

It happen with all servers? then coulb be a eva problem.
is Firmware update?
Switches FC are OK?

Regards, Jorge

Re: not seeing LUN

shashi kanth — Fri, 04 Feb 2011 08:43:49 GMT

I did not see any problem with EVA. Firmware is latest.

No issue with fabric, since the server is seeing the controllers.

Not understanding what could be the problem.

Re: not seeing LUN

Jorge Pons — Fri, 04 Feb 2011 08:51:43 GMT

Hi

- FW OK.
- Switches OK.

Its very strange.... I suposed your EVA is not in production, and you can do some test.

Can you create a vdisk without problems?
its possible to delete vdisk and recreate?
how is configured eva ports?

Regards, Jorge

Re: not seeing LUN

shashi kanth — Fri, 04 Feb 2011 11:19:23 GMT

I can able to create/delete/re-create vDisks.

This time i re-initialized the EVA and created vdisks and presented, but no luck.

I did a small testing.

I removed the EVA and one host out of SAN.

I took one small 2GB 8-port SAN switch, and connected EVA, one HP-UX box and CV EVA server to this Switch. This switch is without any zoning.

rebooted HP-UX box.

But still the box is not seeing LUN. It sees only the EVA controllers.

If you present a vdisk to command view server, can you see the disk?

I create a host entry with for CV EVA server with type as Windows, created a vdisk and presented it, and rescanned/rebooted CV EVA server, but no luck, CV EVA server is not seeing the LUN.

"evainfo -a" say "No EVA Luns discovered"

Re: not seeing LUN

Zinky — Fri, 04 Feb 2011 15:42:46 GMT

IF your EVA 3000 sports a non VCS 4.x.x Firmware -- then it means it is Active/Passive and WILL WORK only on older HP-UX 11i versions where you can install SeceurePath for Active/Passive Arrays.

Re: not seeing LUN

Michael Leu — Sun, 06 Feb 2011 02:01:35 GMT

Did you previously have other vDisks presented from the same EVA?

If so, check syslog for messages like 'Evpd inquiry page 83h/80h failed or the current page 83h/80h data do not match the previous known page 83h/80h data' and 'run scsimgr replace_wwid' as indicated.

Re: not seeing LUN

Zinky — Mon, 07 Feb 2011 14:12:33 GMT

If your EVA3000 is at VCS 3.X.X and you're installing it on HP-UX 11.31 - then it is likely it is NOT supported. HP-UX 11.31 only understands ALUA enabled EVAs -- meaning later generation EVAs and older generation EVAs with the updated VCS 4.x Firmware.

Please check that first.
