Graceful RPM Runtime Software Upgrades

The RPM cards support graceful upgrades when 1:N redundancy is established in the switch between
RPM cards.
In this document, the general term "RPM" refers to RPM-PR and RPM-XF cards. If a step or procedure
Note
is specific to only one of the RPM cards, it will be called out in the text.
The following quickstart procedure describes how to gracefully upgrade runtime software on redundant
RPM cards.
Redundancy must be established before you use this procedure. If redundancy has not been configured
Note
between two RPM cards, upgrade each RPM card as described in the
Software
"Establishing Redundancy Between RPM
Operation."
Release 5.0.10, OL-3845-01 Rev. B0, August 16, 2004
Upgrades" section later in this chapter. To add redundancy to an RPM card, see the
Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, Cisco MGX 8830, and Cisco MGX 8880 Configuration Guide
Purpose
Repeat Steps 4 through 9 to move the upgraded boot software into
bootflash.
This step makes the upgraded primary card active and resets the
secondary RPM card. When the secondary card resets, it loads the
upgraded boot software from bootflash. Both primary and
secondary cards should now be using upgraded boot software.
If there are other primary RPM cards that need upgrading, repeat
the part of this procedure that upgrades the primary card, then
enter the switchredcd command once to reload the primary card.
Finally, enter the switchredcd command a second time to make
the upgraded primary card active.
