BACKGROUND

• In versions 4.0 and above, the name of the boot drive disk group may be named to something other than rootdg.  This procedure will use rootdg as an example; please change the name as appropriate when using the procedure.

• If data volumes have been created in rootdg (using boot disk subdisks), they will be lost using this procedure to remove rootdg objects (the creation of volumes in rootdg is not considered Best Practice)

SUMMARY

1. Boot computer using CD/DVD, network or ram disk (failsafe).
2. Clean boot slice (normaly slice 0) using fsck if necessary.
3. Mount boot slice (s0) onto boot device (CD/DVD and ram disk boot uses /a for mount point).
4. Verify slices on boot drive using prtvtoc.
5. Modify /a/etc/vfstab file as appropriate to mount all slices as reported by prtcvtoc (step 4).
6. Delete or comment the rootdev and vxvi lines in the /a/etc/system file
7. cd /a/etc/vx/reconfig.d/state.d and remove the 0 length flag file root-done.
8. Using the output from step 4, determine the two slices which have TAGS of 15 and 14.
9. Use the OS format tool to zero the length and size of the 2 slices determined in step 8.
10. Reboot the system to the hard disk.
11. Using the mount command or something like df -k, validate that all boot drive slices have mounted to their respective mount point.
