It is specified in the VGDA on both disk. If you are courius type "readvgda \
hdiskX|more"! Anyway the PVID is not equal to device name. PVID is that long number \
(second column in 'lspv'). If you see "none" in that column, try "chdev -l hdiskX -a \
pv=yes"! This command give a PVID to the specified volume, but not destroys the older \
one if existed, just make it visible.
