I've run parallel syncvgs in the past and it has saved me time. I'm not
sure about this VGDA problem: it hasn't affected me before. I've tended to
do "syncvg -l" rather than "syncvg -p", though; maybe that makes a
difference, although it seems unlikely.
My main interest in the "-P" flag is simplicity: I could just run one
command rather than have to analyse how the disks are connected and then run
several different commands.
