SYNOPSIScmrunnode [-v] [node_name...] [-t | -w none]
DESCRIPTIONcmrunnode causes a node to start its cluster daemon to join the exist‐
ing cluster. This command verifies the network configuration before
causing the node to start its cluster daemon.
To start a cluster on one of its nodes, a user must either be supe‐
ruser(UID=0), or have an access policy of FULL_ADMIN allowed in the
cluster configuration file. See access policy in cmquerycl (1m).
Starting a node will not cause any active packages to be moved to the
new node. However, if a package is DOWN, has its switching enabled,
and is able to run on the new node, that package will automatically run
If node_name is not specified, the cluster daemon will be started on
the local node and will join the existing cluster.
cmrunnode supports the following options:
-v Verbose output will be displayed.
-t Test only. Provide an assessment of the package placement
without affecting the current state of the nodes or pack‐
ages. The -w option is not required with the -t option as
-t does not validate network connectivity, but assumes that
all the nodes can meet any external dependencies such as
EMS resources, package subnets, and storage.
Start the cluster daemon on the specified node(s).
By default network probing is performed to check that the
network connectivity is the same as when the cluster was
configured. Any anomalies are reported before the cluster
daemons are started. The -w none option disables this prob‐
ing. The option should only be used if this network config‐
uration is known to be correct from a recent check.
RETURN VALUEcmrunnode returns the following value:
0 Successful completion.
1 Command failed.
Run the cluster daemon on the current node:
Run the cluster daemons on node1 and node2:
cmrunnode node1 node2
