MC SG 11.16 SAN disks cmquerycl fail

maurige — Fri, 29 Oct 2004 06:57:59 GMT

Hello

I m installing MC SG 11.16 on HP-UX11.11
June 2004 with recommended patchset.

HW configuration

2 x rp4440 servers using 2 x HBA A9784A in each computer
Clarion CX500 Storage Processor running the SAN disks

Problem:

When executing "cmquerycl -v -C -n -n "
I get an error message for each VG in the system saying
"Unable to determine a unique identifier for physical volume."
And it tells me to run pvcreate for each and every one of all VG.
All VG are in then Clarion SAN archive.
The command then exits without creating any configuration file.

This is jsut to complete my question with additional traces:

# cmquerycl -v -C cmclnodelist.ascii -n seuxfm001 -n seuxfm002

Hi,

try add option: -k

cmquerycl -k -v -C cmclnodelist.ascii -n seuxfm001 -n seuxfm002

CX600 CLARiion arrays are not supported with Serviceguard.

However, as previously mentioned, the -k option may avoid error messages for each of the SG configuration commands (cmquerycl, cmcheckconf, cmapplyconf, cmgetconf).
Should you choose to use the CLARiion array in the cluster, it is possible to "cluster" volume groups after creating and starting the cluster:
# vgchange -c y
Then add the VGs to the package control script as needed.

NOTE:
This site shows 3rd party arrays which are interoperable with Serviceguard:

FYI, many of the EMC Symmetrix arrays are "supported" with Serviceguard.

-sd.

I believe Clariion is not supported with MC/SG...

Curious why you are calling your ascii file "cmclnodelist.ascii"...

Better to choose name like clustername.ascii

Try with -k as Slawomir suggested..

Hi,

Though EMC may indicate that they support the CLARiion array with Serviceguard, HP has not tested any of these arrays with HPUX (let alone Serviceguard) and do not commit to support them with HPUX.
We have found probs with Service guard v11.16 with this storag combination.Try installing v11.15.

It has been fixed after installation of the HP patch correcting the diskprobing fault named PHSS_31075
Thnaks everybody
