Errh, I'm not sure I'm getting you right but just in case I do: You did WHAT? First you encapsulated the root disk, then rebooted and CHANGED THE PARTITION TABLE by "slicing up the disk".If that's what you did, then why are you surprised you got prob...
Try hdparm -i /dev/xxx and send me the output or post it here. If hdparm cannot get the geometry then vxdisksetup cannot initialize the disk. The output might bring some info as to why it cannot read the geom.

I forgot one thing: use "vxmirror" to mirror the rootdisk, not vxassist. If you already ran vxassist, then issue a "vxbootsetup" command. This will bring your partition tables in sync with the plexes.
Once you mount a partition that is also part of a volume read/write you get inconsistent mirrors because you only change one "side" of the mirror.That can and most likely will lead to unpredictable behavior, most likely sooner or later the system wil...
