7613 Boot in Loop

[mrigank shekhar chaubey]

Hello Everyone,

                        We have a 7613 in our Core. I found that its boot process is in loop with Critical/Non-Recoverable notifications on a couple of modules. Please suggest about the faulty modules (replacement of which could get it back to operational) or workaround.

(I find it unbelievable for two line cards suddenly failing at the same time.)

1.  Please remove whatever line cards are in slot 1 & 2 and reboot again.  

2.  What other line cards are there in this chassis?  I can see something in slots 5, 6 & 7.

Hi @Leo Laohoo,

                               Thanks a lot for your immediate response. I have shared the logs via Private Message.

I've checked the file. Here's what I've found:
1. The chassis has been having issues since 06 November 2018. The entire bootflash is in danger of running out of space because of the amount of crashlog files generated.
2. I see a lot of this error messages: sp_error_detection_recover_sup:Supervisor detected non-recoverable Switch BUS stall error
This points to the line cards not properly secured. Can someone please have a look that they are not "hanging"?
