Hi,


have u tried to mount it manually, also since /dev/dsk/c1t5d0
is busy u have to kill all processes on /dev/dsk/c1t5d0

# kill -9 /dev/dsk/c1t5d0

to stop usage of /dev/dsk/c1t5d0


then try vgchange.

Looks like you need to verify that your discs are really there, do ioscan -fk and see if anything shows up as NO_HW

Also, check the system start log /etc/rc.log and see if anythng was logged as an error in activating any VG's.
You could also try vgchange -a y and see what error that gives you

I think the size 0 Kbytes should be ringing alarm bells. Can you see the disc? E.g. is it in an array? If you can see it, is there a fault light flashing?
