Upgrading to the PRP

Step 6 Upgrade the Mbus-agent-rom using the upgrade mbus-agent-rom all command. Normal forwarding operation of the line cards will not be affected during the upgrade. The line cards do not need to be reloaded. If any error messages are displayed (see following example), repeat this step before contacting Cisco TAC.

MBus agent ROM upgrade failed on slot 7 (rc=5)

MBus agent ROM upgrade failed on slot 8 (rc=6)

Step 7 Use the show version command. If there is an error message at the bottom of the output indicating that a Fabric-downloader code upgrade is required, use the upgrade fabric-downloader all command. Normal forwarding operation of the line cards will not be affected during the upgrade. The line cards do not need to be reloaded. If any error messages are displayed (see following example), repeat this step before contacting Cisco TAC.

Fabric-downloader upgrade failed on slot 7 (rc=5)

Fabric-downloader upgrade failed on slot 8 (rc=6)

Step 8 Upgrade the ROM monitor image in RP1 using the upgrade rom-monitor slot sec-rp-slotcommand. If the routine finds that an upgrade is necessary, the new code will begin to be loaded. Once complete, reload the standby RP using the hw-module standby reload command.

Upgrading the RP ROM Monitor Prior to Cisco IOS Release 12.0(24)S

If your RPs are running a software image prior to Cisco IOS Release 12.0(24)S, you must use the following procedure to upgrade the RP ROM monitor, which requires a reboot of the router.

In the following procedure, RP1 is initially the active RP and RP2 is the standby RP.

Step 1 After you enter the configuration to load the new Cisco IOS software image, reload the standby PRP (RP2) using the hw-module standby reload command.

Step 2 Switch over from the active PRP (RP1) to the standby PRP (RP2) using the redundancy force-switchovercommand. Once RP2 becomes active, the line cards will be reloaded.
