How to update Volume Group information with alternate disk links?
Running autopath and it's showing disks that are different from the disks that are used by LVM.
strings /etc/lvmtab
/dev/vg01_eva
/dev/dsk/c0t0d1
. . .
. ..
pvdisplay -v /dev/dsk/c0t0d1
pvdisplay: Warning: couldn't query physical volume "/dev/dsk/c0t0d1":
The specified path does not correspond to physical volume attached to
this volume group
pvdisplay: Warning: couldn't query all of the physical volumes.
pvdisplay: Couldn't retrieve the names of the physical volumes
belonging to volume group "/dev/vg01_eva".
pvdisplay: Cannot display physical volume "/dev/dsk/c0t0d1".

That same disk shows up as c2t0d1 and c7t0d1 in autopath display. How do I update the VG info with the correct link?
c0t0d1 is the same disk as c2t0d1 but the FC controlled failed, which causes none of the volume groups to activate.
I tried pvchange -a n /dev/dsk/c0t0d1 but could not run it due to volume group not activated, and unable to activate it.
I realize I will have to update the WWW name stuff once I get the FC controlled replaced, but I would like to bring up the VGs now via alternate links.

Re: How to update Volume Group information with alternate disk links?
I tried this to no avail:
# pvchange -s /dev/dsk/c2t0d1
pvchange: Couldn't find the volume group to which
physical volume "/dev/dsk/c2t0d1" belongs.
