7600 with redundant MSFC-2: Switchover fails.

[Mark3000]

Hello,

I have a Cisco 7613 with two modules MSFC2 running 12.2(17d)SXb1. The two modules are for redundancy.

I have note that:

- Module 1 active + module 2 standby: If I take off from the rack the active module, the module 2 does not become active and sometimes crashs... It 's just stays in standby mode !

- Module 1 active + module 2 standby: If I make a soft switch over via CLI: redundancy force-failover, same behaviour: the module 2 does not become active and sometimes crashs... It 's just stays in standby mode !

Any help .? Thx in advance.

Can you see if there is a crashinfo in the Supervisor in slot 2? If slot 1 is active, you can do a "dir slavebootflash:" and "dir slavesup-bootflash:". If you have a crashinfo, attach it along with an output of sh ver, sh mod.

Thx in advance for any helpfull information.

The standby is failing due to inbandping failure.

I did some research and found couple bugs which were internally found during testing and this issue was not seen in later releases. If the standby Supervisor stays long enough, upgrade your IOS to 12.2(17d)SXB5. If it does not, pull out one Supervisor and upgrade one supervisor at a time and see if it stabilizes.
