Did you ever add the disk to a VG? I don't remember to what software "vpath" belongs - what is it?

i am also little unsure about vpath...is it linux, anyways you will have to add the disk in a vg then only you would get a propoer pvdisplay output.

Hi,

follow the steps

(1) diskinfo /dev/rdsk/cxtxdx check it is showing the proper size of disk

(2) # pvcreate /dev/rdsk/cxtxdx
(3)# vgextend /dev/vgname /dev/dsk/cxtxdx

now check assigned pv to VG

(4) strings /etc/lvmtab
