򐂰 In the merging process:
– The primary system scans for resources of all merged nodes in the
installed processor packages and memory, and then indicates how much
of it is available.
– The main memory is decreased by 256 MB for each merged system.
򐂰
After a merge is successful:
– The video window on the primary system is active and contains all
information in POST or in the operating system.
– The video window at all other nodes is active and tells you that you can
watch the window on the primary node.
– The white scalability LED on the front of all systems that merged to a
partition as part of a multinode system becomes solid
on
. See Figure 4-29
on page 231.
– The port link LEDs on the rear of all systems that merged to a partition
becomes solid on green. See Figure 4-29 on page 231.
– The scalability LED at the front and the port link LEDs at the rear of the
systems go off again, if the scalability mode is changed after a partition is
started and rebooted to start in stand-alone mode.
򐂰
If a merge is unsuccessful:
– The node or nodes that could not be merged boot in stand-alone mode.
– All nodes that could be merged boot as multinode system if the partial
merge flag is enabled.
– If the scalability LED at the front and the port link LEDs of a system are off,
then this system is not part of a scalability partition or has not merged to a
partition.
– The system event log in the RSA II and Baseboard Management
Controller report the timeout and additional error events, at least on the
particular affected node.
򐂰 The POST process and the loading of the operating system are shown on the
window only at the primary system, as follows:
– PCIe devices that are integrated or installed in the other systems at this
partition are visible on the window on the primary server.
– The started operating system provides all resources at this partition as
though it is one system.
