[c-nsp] c6509 booting in ROMMON

[Youssef Bengelloun-Zahr]

Hello list,

I have tried to debug this for a long time but I'm stuck. Here is the
situation.

I have a SUP720-3BXL (MSFC3) running on
s72033-advipservicesk9_wan-mz.122-33.SXH2a.bin that went crazy just before
X-mas eve, after two years of loyal services !

After some log reading, I found out I was affected by bug CSCsc33990 :

Causes and Resolutions:
* If there is any corruption in the TCAM entries, the *SPRPInbandPing test
can fail*. If the test, ran as
part of Cisco Generic Online Diagnostics (GOLD), fails 10 times
consecutively, then the supervisor
engine can crash.

In order to resolve the issue, upgrade the Cisco IOS software to a release
not affected by Cisco bug ID
CSCsc33990 ( registered customers only) .

* If health-monitoring is enabled on the device and complete diagnostics is
configured during the
startup, then the supervisor can crash at the time of the boot process.
Health-monitoring and complete diagnostics conflict with each other for some
tests. As a
workaround, disable either of them, which depends on your requirement.



I have taken back the faulty card back to my office where I have a spare
chassi (comes in handy sometimes ;-) and now the sup720 boots in ROMMON.

I thought maybe my bootdisk (sup-bootflash or sup-bootdisk) whas corrupted
because It was old. I tried this :

- boot on disk0 with the same IOS  ===> OK

- format bootdisk then copy IOS from disk0: to bootdisk: ===> OK

- Reload with my bootvar pointing to the image on bootdisk: ===> NOK

- from ROMMON, boot using the image on bootdisk: ===> OK  (look below for
output)

I Decided then to change th CF on the SUP720 with a brand new one, no
change. I am still experiencing the same symptoms.



Any ideas what might cause this ? Would you recommend an upgrade in order to
solve this ? Is my SUP720 dead ?

Thanks for your feedback.

Best regards.

Y.
