Re: Cannot see vg02 /usr/informix
This sounds like the device file is missing (which is what the error and error number say).
Do:
# ls -l /dev/vg02
If the device file(s) are missing, you could try a 'vgexport' and then a 'vgimport'.
Regards!

Re: Cannot see vg02 /usr/informix
Do pvdisplay on each one of them.
this will return the vg it belongs to.

Re: Cannot see vg02 /usr/informix
>>Quorum not present
Try to activate the Vg in low quorum mode.
# vgchange -a y -q n vg02
If two disks are present then probably one disk is missing or gone bad.
What is the status of /dev/dsk/c0t0d0 and /dev/dsk/c0t1d0 in:
# ioscan -fnC disk
Are they claimed??

Re: Cannot see vg02 /usr/informix
ioscan -nfC disk |grep -i no_hw
I think disks are missing...
