Doc Text Cause: The rolling_update.yml contains the comment "Change the value of 'serial:' to adjust the number of server to be updated."

Consequence: The value of serial should always be 1 for rolling update for all nodes. Changing this value to greater than 1 and running playbook may result in disruption to IOs as those many number of nodes get updated in parallel.

Workaround (if any): Default value of 1 should not be changed

Result:

Result:
.The serial parameter must be set to 1

The `rolling_update.yml` Ansible playbook contains a comment about changing the value for the `serial` parameter to adjust the number of servers to be updated. However, the value of `serial` must be always set to `1` for all nodes because upgrading many nodes in parallel can cause disruption to I/O operations. To avoid this problem, ensure that `serial` is set to `1`.
