clusters of KVM hosts that run on RHEL 6.0, RHEL 6.1, or RHEL 6.2 operating system, you must

from RHEL 6.0 or 6.1 ”

It is assumed in the following procedures that you have set the root password on the MySQL
database as per the CCP best practices recommendation. In the following commands, substitute
your own MySQL root password.
# mysqldump -u root -p<mysql_password> cloud > cloud-backup.dmp
# mysqldump -u root -p<mysql_password> cloud_usage > cloud-usage-backup.dmp
