POWER3 SMP High Node characteristics

The POWER3 SMP High Node is different from other nodes in several areas:

• The architecture of these nodes conforms to the RS/6000 Platform Architecture (RPA). Node firmware performs low-level tasks, allowing operating systems like AIX to be less hardware-dependent.

  To see the installed hardware of an RPA node, as discovered and recognized by the firmware, issue this AIX command:

  /usr/lib/boot/bin/dmpdt_chrp
  

• The RPA dictates that there is no key switch on these nodes. In order for a node to be ready to produce a dump when the node is reset, the AIX command:

  /usr/bin/sysdumpdev -K
  

  must be issued before a dump-on-demand condition arises.

  The -K (upper case K) flag is the default for the node. The AIX command:

  /usr/bin/sysdumpdev -k
  

  (lower case k) resets the setting.
