Replacing Master Processor of Multi-Processor Node

Introduction	This section describes how to replace a failed master processor in a multiprocessor
	node without losing your configuration.
Keeping the
	All processor cards in a node contain identical copies of CMEM. If the master

Configuration		• Replace the master processor with another processor card from the node
		(preserving the configuration).
		• Keep the ID Module of the original master, retaining the original SAKs for
		the options you purchased.
Replacement of
	To replace a processor card other than the master, remove the old processor card and
Other Processor	insert the new one. Be sure you use the correct type of ID Module (for example,
Cards	6505, 6507, or 6525). You do not have to change the configuration. When the node
	starts up, the CMEM on the new processor card is loaded automatically with the
	node configuration.
		Note
		All processor cards in a multiprocessor configuration must operate on the same
		revision of software. If they do not have the same software revision, remove the
		software from the failed processor card and exchange it with the software on the
		spare card. All processor cards in a multiprocessor configuration must use the
		same type of ID Modules—the node must be composed entirely of one type of
		processor card (6505, or 6507, or 6525 cards).
Replace the Master Follow these steps to replace the master processor:

	This procedure saves your configuration. If you do not use this procedure to replace
