Volume Manager start up scripts are in "/etc/init.d" at boot they run from level S "/etc/rcS.d":
vxvm-sysboot - this configures "/" and "/usr".
vxstartup1 - (must run after "sysboot"
, makes other volumes available.
vxstartup2 - (must run after "sysboot" and "startup1", start all volumes.
...
vxvm-rdac - Start RDAC devices under Volume Manager control.
vxvm-reconfig - is runned after a fsck on root filesystem "/".
Hope it helps,

Its good - Its very useful for future reference, but I got a bit further with the problem last week, before our Internet access got Nimba-ed out.
All I wanted to do, really, was make changes to the root partition. In this case, it was to make an empty /usr directory to mount a usr volume on.
Boot CDrom, mount root partition, make changes. Disable rootdev in /etc/system, replace rootvol with partition in vfstab, boot from partition. Worked fine, but when I disabled the old (now stale) mirror and reversed the /etc/system and vfstab changes and rebooted, the new usr directory wasnt there!
If I mounted the bare partition it was okay, but when I went back to mount the rootvol, it wasnt.
Eventually I had to de-encapaulate the whole disk and re-encapsulate.
There must be a (reasonably) simple way of doing these sort of simple changes (eg root password reset, when you dont have it)??
