Scalable-partition configuration
The Scalable Partition Web Interface is an extension of the RSA-II Web
Interface and is used to create, delete, control, and view scalable partitions. The
Scalable Partition Web Interface is in the RSA-II integrated service processor.
The scalable partition defines a multi-node configuration, which interconnects
two or four servers.The multi-node configuration provides the function to individ-
ually power-on and power-off each node. The multi-node configuration uses a
single, contiguous memory space and provides access to all associated
adapters. Each multi-node configuration can have one or more scalable parti-
tions.
Before you create or delete scalable partitions, read the following information:
All of the RSA-IIs must be connected to an Ethernet network through the SP
connector on the rear of the node. This connection is needed so that the
RSA-IIs can communicate with and manage scalable partitions.
Make sure that all nodes in the multi-node configuration have the current
level of BIOS code, SAS BIOS code, service processor firmware, BMC
firmware, and CPLD firmware. The code and firmware levels must be the
same for all nodes.
When you set up the nodes for scalable partitions for the first time, you must
first log on and configure the service processor in each node.
PCI slot numbering starts with the primary node and continues with the
secondary nodes, in numeric order of the logical node IDs.
Creating a scalable partition
To create a scalable partition, complete the following steps:
Ê Make sure that the RSA-II on each node is configured and connected to the
network. See the RSA-II user manual for more information.
Ê Make sure that all nodes in the multi-node configuration contain micropro-
cessors that are the same cache size and type, and the same clock speed
(see "BIOS Setup" on page 54).
Ê Connect the SMP Expansion cables. See "SMP Expansion cabling" on
page 37 for instructions.
Ê Connect all nodes to an AC power source and make sure that they are not
running an operating system.
