Health status changes to 'Attention' when password of host is changed
Health status of host changes to 'Attention' when you change the password.
Problem
Health status of host changes to 'Attention' when you change the password and gives the following error:Nova agent state of Host <ip_address> is Error, Ceilometer agent state of Host <ip_address> is ErrorExplanation
When you change
a password, the changed password is not reflected in the conf files
that the PowerVC server
relies on. Also, the state of the hypervisor remains unchanged as
the compute process is not able to get the latest value of hypervisor_state.
However,
as the previous value of hypervisor_state is set
to 'Operating', the health process continues to poll the Nova and
Ceilometer agent service state. If the health process is unable to
communicate with the host, the Nova and Ceilometer agent service state
is set to 'Error'.
