IBM 71453RU manual Partitioning an EXA multi-node system

Note: To reorder the sequence in which the nodes appear in the diagram on the page, click Redraw. For example, you can reorder the diagram to reflect the order in which the nodes are physically installed in a rack. The nodes are reordered according to the QPI or EXA cabling, with the node that you select in the top position.

Partitioning an EXA multi-node system

There are two ways to partition an EXA multi-node system into stand-alone servers: deleting the partition configuration and forcing a stand-alone boot. Both methods are performed through the IMM web interface from the Manage Partition(s) page, through the IMM in either server. The benefit of forcing a stand-alone boot is that you can restore the original partition information by clicking Undo.

Note: For instructions for creating, modifying, and controlling partitions through the IMM Telnet interface, see “Using the IMM Telnet interface” on page 114.

To partition an EXA multi-node system, complete the following steps:

1.Connect and log in to the IMM web interface.

2.Make sure that the scaled system is powered off. In the navigation pane, expand Scalable Partitioning, and click Manage Partition(s). Both nodes should be indicated as stopped.

3.Select the chassis that you are connected to through the IMM. The interface control for the other chassis should be disabled.

4.Determine which method you plan to use to partition the multi-node server:

vTo delete the partition, click Partition Configuration, and then click Delete.

vTo force a stand-alone boot, click Standalone Boot, and then click Force.
