======================
Removing the Root disk
======================

1)  # vxdg -g rootdg -k rmdisk <root disk dm name>

2)  # vxprint -htg rootdg
remove the plexs associated with the original disk (disabled nodevice)

3)  # vxplex dis opt-01 (run against all plexes associated with root disk)
- this is a standard plex that is creatd in encapsulation

4)  # vxedit -r rm opt-01 (run against all plexes associated with root disk)

5)  # vxedit rm <root disk dm name>

6)  # vxdisk list
should no longer be listed as a removed entry

7)  # vxdisk rm c#t#d#s2 (root disk)



=======================
Replacing the root disk
=======================

1)  preform drive replacement steps per system requirements
if drive has already been replaced, skip this step

2)  # format
Delete all partitions except for slice 2, and label the disk

3)  # vxdctl enable

4)  # vxdisksetup -i c#t#d# (rootdisk)

5)  # vxdg -g rootdg adddisk rootdisk=c#t#d#

6)  # vxdiskadm - opt6 to mirror
choose root mirror as the disk to mirror
root disk is destination disk
this should recognize that it should be a root disk and write a
bootblock onto it

7)  # prtvtoc /dev/rdsk/c#t#d#s2 (rootdisk)
check to make sure that there are regular partitions
