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
Original Node
Configuration All processor cards in a node contain identical copies of CMEM. If the master
processor fails, you can keep the original node configuration and options if you:
• 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
Other Processor
Cards To replace a processor card other than the master, remove the old processor card and
insert the new one. Be sure you use the correct type of ID Module (for example,
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
Processor Follow these steps to replace the master processor:
Caution
This procedure saves your configuration. If you do not use this procedure to replace
the master processor card, the default configuration is transferred to the other
processor cards in the node and you must reenter or download your configuration.
Step Action Result/Description
1 Remove the failed processor
card from the lowest-
numbered slot in the node.
2 Exchange the ID Module and
the CMEM chip between the
failed master processor card
and the new processor card. See the “Replacing ID Modules” section
on page 2-63 and “Replacing the
CMEM Chip” section on page 2-65 for
instructions. Return the failed card to
your VanguardMS Service representa-
tive.
3 Install the new processor card
into the lowest-numbered slot. This will now be the master processor.
4 Boot the node.
