If any volume contains more than one plex (mirror), all but one plex should
be removed.
To display a list of all volumes, use the command
vxprint -Ath
To remove a plex, use the command:
vxplex -o rm dis plex-name
See
vxplex(1M).
NOTE:
Leave exactly one plex for the special volumes rootvol,
swapvol, and standvol.
Make the remaining plex for each volume consist of one subdisk on
physical disk c0b0t0d0s0.
These subdisks must be either the original subdisks created
by running vxinstall or they must have been created using
vxrootmir(1M)
or the
vxdiskadd(1M)
mirror disk operation.
