    Ok here is an idea...If i add a smaller disk to rootdg and then remove the current disk from rootdg leaving the smaller disk in rootdg, think that will work?   If not we will just use rootdg as it is and put a filesystem on that dg. As you see there are no volumes in rootdg on the one disk.  Also before i got everything working i placed vxconfigd in disable mode "vxconfigd -k -m disable".  I then ran vxdctl enable and know if i do type "vxdctl mode" it shows it is enable.   Is it ok now to run stop vxconfigd and restart as normal "vxconfigd".   All the volumes are now enabled and fsck'd and filesystems are mounted.   If not we will just use rootdg as it is and create a volume and filesystem on that dg.
