    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.
