Executing a command on a list of nodes
To execute a command on multiple nodes, you must specify the names of nodes.
cmu> boot o185i222 o185i233 o185i243
active node list selected: o185i222 o185i233 o185i243
cmu>
Executing a command on a range of nodes
To execute a command on a range of nodes, you must specify the range using their attributes.
Commands are executed on all nodes within the range.
cmu> boot o185i222 - o185i225
active node list selected: o185i222 o185i223 o185i224 o185i225
cmu>
IMPORTANT: Spaces between “-” and node names are mandatory.
Using wildcards
You can use the * as a wildcard to select all nodes with matching node names. For example:
cmu> nodes o185i22*
active node list selected: o185i220 o185i221 o185i222 o185i223 o185i224 o185i225 o185i226 o185i227 o185i228
o185i229
cmu>
Complex list of nodes
A complex list of nodes can be specified using any combination of the above regular expressions.
NOTE: If a node is mentioned twice, the command is executed twice on this node.
To boot specific nodes:
cmu> boot o185i209 o185i217 o185i22* o185i232 - o185i235
active node list selected: o185i209 o185i217 o185i220 o185i221 o185i222 o185i223 o185i224 o185i225 o185i226
o185i227 o185i228 o185i229 o185i232 o185i233 o185i234 o185i235
cmu>
Executing a command on all nodes
A command followed by the all option is executed on all nodes.
cmu> boot all

Excluding specific nodes from a command
Use the allbut option to select all nodes except specific ones. The allbut option can be followed
by any combination of the above regular expressions.
cmu> boot allbut o185i2*
active node list selected: o185i192 o185i193 o185i194 o185i195 o185i196 o185i197 o185i198 o185i199
cmu>
Executing a command on all nodes of a logical group
You can use the all option followed by a group name to select all active nodes of this group.
cmu> boot all default
active node list selected: o185i194 o185i202 o185i216 o185i222 o185i233 o185i243 o185i252 o185i253 o185i254
