   # touch /etc/vx/reconfig.d/state.d/install-db

   # umount mnt_point

3. Stop all the volumes by entering the following command for each disk group:

   # vxvol -g diskgroup stopall

4. If you are upgrading a high availability (HA) product, take all service groups offline.

   List all service groups:

   # /opt/VRTSvcs/bin/hagrp -list

   For each service group listed, take it offline:

   # /opt/VRTSvcs/bin/hagrp -offline service_group \
       -sys system_name

5. Stop the VEA backend service by entering the following command:

   # /opt/VRTS/bin/vxsvcctrl stop
