Cluster and Package Maintenance
Reviewing Cluster and Package Status
Chapter 7 279
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.
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:
• Auto Run. Enabled means that the package can switch to another
node in the event of failure.
