resls /vg only shows vg00 in Serviceguard environment

[lshu]

Hi,

I have a HP-UX 11iv3 March 2009 with Enterprise OE. There are a few VGs created from SAN storage disks in the SG cluster. Latest EMS and HA Monitor are installed. But resls or emscli only shows vg00.
[root@vmhost ./root]# resls /vg
There is one resource configured below /vg:
Resource Class
/vg/vg00

What is missing to prevent resls showing VGs in cluster?

Your help is highly appreciated.

If resls /vg shows /dev/vg00, EMS appears to be working.
Does the following show other VG names?
# strings /etc/lvmtab | grep dev | grep -v sk

No, they are not in the /etc/lvmtab as they are managed by SG cluster.

Even if they are managed by Serviceguard they should appear in /etc/lvmtab. Volume groups managed by SG are still imported and should be imported on all cluster systems at the same time and therefore should appear in lvmtab. If they are not in lvmtab they are not imported and resls will not show them.

Hmm... are the cluster VGs created with LVM, or with VxVM?

By a very quick browse through EMS & HA Monitor documentation, it seemed to me that "resls /vg" is for *LVM* volume groups only.

If vg00 uses LVM and all the other volume groups are created with VxVM, that might explain it.

Hi,

I checked that the VGs are created with "vgcreate -V 2.0 ...", so the LVM info is not found in /etc/lvmtab but in /etc/lvmtab_p.

Does it mean EMS HA Monitor not working with version 2.0 volume group?

thanks,
Lorne
