IBM BladeCenter HX5 offers flexibility ideal that the blades can be combined together for scalability.
There are several concepts to support the HX5 multiple blades combination:
=over 2
B<Complex>: Multiple blades which combined by a scalability card is a complex.
B<Parition>: A logic concept which containing part of the B<Blade slot node> in a complex. Each partition can map to a system to install Operating System. Each partition could have 1HX5, 1HX5+1MD or 2HX5+2MD. (MD is the Memory Drawer)
B<Blade slot node>: The physical blade which installed in the slot of a chassis. It can be a HX5 or MD.
=back
A B<Complex> will be created automatically when a multiple blades combination is installed. In this B<Complex>, every blade belongs to it is working as a B<Blade slot node>.
A B<Partition> can be created base on the B<Complex>, each B<Partition> can have one or multiple B<Blade slot node>.
The I<noderange> in the B<SYNOPSIS> can be a AMM node or a blade node.
The meaning of attributes which displayed by the B<lsflexnode>. The word 'node' in this section means B<Blade slot node>.
=over 4
=item B<Complex>
The unique numeric identifier for a complex installed in the chassis.
=item B<Partition number>
The number of partitions currently defined for this complex.
=item B<Complex node number>
The number of nodes existing in this complex, regardless of their assignment to any given partition.
=item B<Partition>
The unique numeric identifier for a partition defined within a complex installed in the chassis.
=item B<Partition Mode>
The currently configured mode of this partition. It can be 'partition' or 'standalone'.
=item B<Partition node number>
The number of nodes currently defined for this partition.
=item B<Partition status>
The current power status of this partition when the partition has a valid partition configuration. It can be 'poweredoff', 'poweredon', 'resetting' or 'invalid'.
=item B<Node>
The unique numeric identifier for this node, unique within the partition. If this node does not belong to a partition, the slot number will be displayed.
=item B<Node state>
The physical power state of this node. It can be 'poweredoff', 'poweredon' or 'resetting'.
=item B<Node slot>
The base slot number where the node exists in the chassis.
=item B<Node resource>
A string providing a summary overview of the resources provided by this node. It includes the CPU number, CPU frequency and Memory size.
=item B<Node type>
The general categorization of the node. It can be 'processor', 'memory' or 'io'.
=item B<Node role>
Indicates if the node is assigned to a partition, and if so, provides an indication of whether the node is the primary node of the partition or not.
=item B<Flexnode state>
The state of a flexible node. It is the state of the partition which this node belongs to. If this node does NOT belong to a partition, the value should be 'invalid'.
It can be 'poweredoff', 'poweredon', 'resetting' or 'invalid'.
=item B<Complex id>
The identifier of the complex this node belongs to.
=item B<Partition id>
The identifier of the partition this node belongs to.
