Node Status and State
The status of a node is either up (active as a member of the cluster) or down (inactive in
the cluster), depending on whether its cluster daemon is running or not. Note that a
node might be down from the cluster perspective, but still up and running HP-UX.
A node may also be in one of the following states:
• Failed. A node never sees itself in this state. Other active members of the cluster
will see a node in this state if that node was in an active cluster, but is no longer,
and is not halted.
• Reforming. A node is in this state when the cluster is re-forming. The node is
currently running the protocols which ensure that all nodes agree to the new
membership of an active cluster. If agreement is reached, the status database is
updated to reflect the new cluster membership.
• Running. A node in this state has completed all required activity for the last
re-formation and is operating normally.
• Halted. A node never sees itself in this state. Other nodes will see it in this state
after the node has gracefully left the active cluster, for instance with a cmhaltnode
command.
• Unknown. A node never sees itself in this state. Other nodes assign a node this
state if it has never been an active cluster member.
Package Status and State
The status of a package can be one of the following:
• Up. The package control script is active.
• Down. The package control script is not active.
• Unknown.
A system multi-node package is up when it is running on all the active cluster nodes.
A multi-node package is up if it is running on any of its configured nodes.
The state of the package can be one of the following:
• Starting. The start instructions in the control script are being run.
• Running. Services are active and being monitored.
• Halting. The halt instructions in the control script are being run.
Package Switching Attributes
Packages also have the following switching attributes:
• Package Switching. Enabled means that the package can switch to another
node in the event of failure.
• Switching Enabled for a Node. Enabled means that the package can switch
to the referenced node. Disabled means that the package cannot switch to the
