The 332 MHz node was the first SP system SMP node offered in either a thin or wide footprint. Previous SMP nodes were available only as high nodes.
In order to provide an SMP in these denser packages, the power and cooling design is more like that of earlier thin and wide uniprocessor nodes. N+1 power and cooling is not offered for these nodes.
The 332 MHz SMP node is different from other nodes due to these characteristics:
must be issued before a dump-on-demand condition arises.
The -K (upper case K) flag is most likely the default for the node. The AIX command:
(lower case k) resets the setting.
