Example: Two Partitions Sharing a Node

The next example shows a second partition, part1, being created. One of its nodes, node1, is also a member of part1.

[node0]
P[part0]:: up[node0] Partition:: create part1[node0] P[part1]:: set nodes=node1 node2 node3[node0] P[part1]:: list
    node1
    node2
    node3
[node0] P[part1]::

Because node1 is shared with part0, which is already enabled, part1 is not being enabled at this time. This illustrates the rule that a node can be a member of more than one partition, but only one of those partitions can be enabled at a time.

If both partitions were enabled at the same time and you tried to run a job on either, the CRE would fail and return an error message. When you want to use part1, you will need to disable part0 first.

Note the use of the up command. The up command moves the context up one level, in this case, from the context of a particular partition (that is, from part0) to the general Partition context.
