Perform this procedure if you configured rootability by encapsulating the root disk.
To remove rootability
# df -v /
The root disk is under VxVM control if /dev/vx/dsk/rootdg/rootvol is listed as being mounted as the root (/) file system. If so, unmirror and unencapsulate the root disk as described in the following steps:
For example, the following command removes the plexes mirrootvol-01, and mirswapvol-01 that are configured on a disk other than the root disk:
# vxplex -o rm dis mirrootvol-01 mirswapvol-01
# /etc/vx/bin/vxunroot
Following the removal of encapsulation, the system is rebooted from the unencapsulated root disk.
