Executing a command on specific nodes of a logical group
You can use the but option to exclude active nodes of a group from the selection. Nodes to exclude
can be specified with any combination of regular expressions.
cmu> boot all default but o185i222 - o185i252
active node list selected: o185i194 o185i202 o185i216 o185i253 o185i254

7.17.4 Administration and cloning commands
Booting a set of nodes
You can boot any number of nodes in the cluster. Regular expressions to specify a list of nodes
described above are accepted.
The boot modes are:
• Normal mode boots nodes on the default device, generally the hard drive.
• Network mode fills the dhcpd.conf file to boot nodes over the network.
cmu> boot [net] cmu_nodes_regular_expression
Booting node o185i192 normal on the hard drive:
cmu> boot o185i192
active node list selected: o185i192
Entering normal Boot
Booting node o185i192
Not using ssh/rsh shutdown because node o185i192 is not pinging
Doing a powercycle of node o185i192 via lo100i (OFF then ON)
Boot order has been sent to every node
Boot process finished !!
Please read /opt/cmu/log/Boot-lo100i-Tue-08-Aug-at-12h36m23s.log to check errors
cmu>
Booting node o185i192 with the network:
cmu> boot net o185i192
active node list selected: o185i192
Cleaning previous kickstart boot option
Copying /etc/hosts to /opt/cmu/ntbt/rp/etc/
Entering Network boot
Writing dhcpd.conf
dhcpd.conf written successfully
Booting node o185i192
Not using ssh/rsh shutdown because node o185i192 is not pinging
Doing a powercycle of node o185i192 via lo100i (OFF then ON)
Waiting 1 second (cooldown)...
Waiting 5 minutes before removing the dhcpd.conf
Boot process finished !!

Broadcasting commands to a set of nodes
Broadcast launches the interactive single window broadcast utility. You can use the regular
expressions described above to specify nodes. The command uses telnet and secure shell.
NOTE: This command has limited functionality. For more information on this command, see
“Multiple windows broadcast” (page 121).
