Merging timeout
This is the time that the system waits for the merge process to complete. If the
merge process does not complete within this time, the nodes in the partition
are booted in standalone mode instead. The default value is six seconds.
Multinode mode
A created partition is started, merges successfully, and is running as a single
image.
Stand-alone mode
A node is booted separately and not merged in a partition.
Partition
A partition is the merging process of one or more nodes within a multinode
complex. It is seen in any type of a supported operating system as one
system. Partitioning can be performed at any time to add or remove a node in
it to scale resources, but does require a reboot to activate.
This is a more flexible alternative to recabling your systems in a complex.
ScaleXpander
This is the scalability enablement chip, which is a hardware component that is
inserted into a dedicated socket to enable a system to join a multinode
complex. See Figure 4-5 on page 205.
Primary node
This is the lead node in a configured partition.
Secondary nodes
These are all other nodes in a configured partition.
