I have booted off the mirror (/dev/dsk/c2t1d0) and am getting the error.


vgdisplay: Warning: couldn't query physical volume "/dev/dsk/c2t0d0":
The specified path does not correspond to physical volume attached to
this volume group
vgdisplay: Warning: couldn't query all of the physical volumes.

Dead disk? Check with "dd"!

Hi Douglass,

>> I have booted off the mirror
Any particular reason for this?

Has the disk c2t0d0 gone bad?

Try following tests on c2t0d0:
-diskinfo /dev/rdsk/c2t0d0
-pvdisplay /dev/dsk/c2t0d0
-dd

Reason I booted off this second disk was I needed to change file system sizes of vg00.

I created an ignite tape no errors.
Loaded ignite onto the disk with no errors.
After reboot the system was missing PATH and some directories. (/var/adm, /var/spool, /opt/programname)

Very odd, so I booted off mirror to get the system back up
