Protocol Manager
Protocol Manager manages networking protocols and IP address assignment across the entire
SnapScale. If a node fails or is removed from the SnapScale, Protocol Manager handles
automatic IP address reassignment to maintain client access to data.
The following table addresses the possible status:
Status
Description
OK
This node is fully functional.
Disconnected
This node could not be connected through the Storage
network and is currently not participating in the cluster. If
there is a public IP address associated with this node it should
have been taken over by a different node. No services are
running on this node.
Banned
This node failed too many recovery attempts and has been
banned from participating in the cluster temporarily. Any
public IP addresses have been taken over by other nodes.
Disabled
This node has been administratively disabled. This node is still
functional and participates in the cluster but its IP addresses
have been taken over by a different node and no services are
currently being hosted.
Unhealthy
A service provided by this node is malfunctioning. The node
itself is operational and participates in the cluster, however its
public IP addresses have been taken over by a different node
and no services are currently being hosted.
Stopped
A node that is stopped does not host any public IP addresses,
and does not participate in the cluster.
