RHACS: Procedure to shutdown/scale down RHACS and change /dev/sdx to UUID path in local volumes

Issue

• RHACS installation using local volumes had /dev/sdx paths instead of /dev/disk/by-uuid/, which caused an issue as /dev/sdx is dynamically allocated and can change if the order of device detection changes. There is a need to scale down RHACS and replace the /dev/sdx with the /dev/disk/by-uuid/ path in local volumes used in RHACS.
