1. Switch the cloud to maintenance mode at Control Panel > Sysadmin > Control Panel Maintenance. Run the following commands on all Control Panel servers:

2. Issue the following command:

   1	# rpm -Uvh http://rpm.repo.onapp.com/repo/onapp-repo-5.1.noarch.rpm

3. Unmanage RabbitMQ service:

   1	# crm resource unmanage onapp-mq-cluster

4. Stop rabbitmq-server on each node:

   1	# service rabbitmq-server stop

5. Upgrade the Virtuozzo OnApp installer package on CP nodes:

   1	# yum -y update onapp-cp-install

6. Upgrade the RabbitMQ packages on remote nodes:

   1	# yum -y update rabbitmq-server rabbitmq-admin erlang

7. Start rabbitmq service on remote nodes:

   1	# service rabbitmq-server start

8. Ensure that RabbitMQ cluster is working:

   1	# rabbitmqctl cluster_status

9. Delete old queues from the RabbitMQ cluster. This command should be run on any remote node without CP

   1	# rabbitmqctl list_queues | grep 0 | awk '{print $1}' | xargs -I qn python /usr/local/bin/rabbitmqadmin -u <user> -p <password> delete queue name=qn</password></user>

   You can find the and parameters on the remote RabbitMQ nodes by using this command:

After you have successfully run the previous commands on all Control Panel servers, issue the following commands on one of the CP servers:

1. Switch all nodes back online by running the following command once on any of the nodes:

   1	# crm configure property maintenance-mode=false

2. Enable monitoring onapp-mq-cluster:

   1	# crm resource manage onapp-mq-cluster

3. Enable file synchronization on all nodes by running the following command once on any of the nodes:
