I read a vxbrk_rootmir:
in the script i see this:

#
# Check if the bootdg contains any extra disks in addition to the disks
# containing the boot volumes and their mirrors (apart from the specified dm).
# If yes, then abort the operation here.
# This is a restriction which was put for MBNA when this script was developed.
# The way the breakoff is done in this script is by patching the "dgname"
# using vxprivutil. Since this is not a transactional way of doing things,
# this restriction was imposed.
#

any idea?
