Creating an EXA multi-node system
This topic provides information about creating an EXA multi-node system.
About this task
The following information provides instructions for creating an EXA multi-node
system from multiple servers and configuring it as a single logical 8-socket server.
Note: To check for the latest firmware levels and to download firmware updates,
go to http://www.ibm.com/supportportal/.
Before you create an EXA multi-node system, make sure that all the nodes in the
multi-node configuration contain the following software and hardware:
v The current level of UEFI firmware, SAS UEFI code, IMM firmware, and FPGA
v Microprocessors that are the same cache size, type, and clock speed
Note: All the nodes must have all the microprocessor sockets and memory
connectors populated.
To create a scalable partition, complete the following steps:
1. Connect the EXA cables. For detailed instructions, see the documentation that
2. Connect all nodes to an ac power source and make sure that they are not
3. Connect and log in to the IMM web interface.

running an operating system.
Note: All nodes that are part of an existing partition and are connected
through EXA cables must be in Standalone mode (part of the partition but
operating independently). To enable Standalone mode, on the Scalable Complex
Management page, click Standalone Boot, and then click Force.
Note: For instructions for creating, modifying, and controlling partitions
