How can you identify when a RP has a bootflash failure on CRS-1?

[rpatnaik]

Hi Everyone,

I am hoping someone can assist me in identifying when a RP has a bootflash issue and requires RMA.  We have some CRS-1 running in our network with IOS XR 3.8.2 and some with 4.0.3.  All the commands that I am aware of do not identify when a RP has a problem in bootflash.  CCO recommends that if there is a problem with upgrade and you are moving to a code using filesystem fat 32 that you format the bootflash of the RP's.  It was at this point we started having issues.  We went into ROMMON and recieved the following error.

rommon B1 > dir bootflash:disk0/hfr-os-mbi-4.0.3

Checksum failed on hfr-fslib-m

Expected checksum: 6a53, calculated checksum: beba

open: file "hfr-fslib-m" not found

loadprog: error - on file open

cannot load the monitor library "bootflash:%hfr-fslib-m" from device

If someone has some insight on how we can validate the state of the RP outside of the typical command set:

show redundancy summary

show platform

etc

I'd appreciate it.

Cheers,
Rashmi

Hi,

Provide some more information on your problem.

If you want to check the directory contect try

dir bootflash:

is it displaying any output?

In general above error doesn't indicate that there is any problem but it is not able to find particular directory or file.

Thanks
