The active RP of ASR 1006 router automatically switched over to standby while the standby assumed the active role.
Not sure the exact reason for this behaviour. The image version is 122-33.XNB1. We noticed an outage when the switchover happened but the device did not crash.

In the output of "show redundancy switchover history" the switchover reason given is active unit failed.
But currently the RPs are working as active and standby hot.
Thanks for your response... I hope the bootflash and harddisk you are refferring is that of the rp that switched over to standby. However when we checked the output of "show stby-bootflash:" and "show stby-harddisk:" it doesn't show anything. Below is the output from the show tech after the switchover.
------------------ show stby-bootflash: all ------------------
------------------ show stby-harddisk: all ------------------
------------------ show stby-obfl: all ------------------
And the bootflash of the current active rp doesn't show any crashinfo related to this switchover. Do we need to do a force fail-over and then check the bootflash and harddisk of the active rp?
I tried searching for bugs which would explain why the files aren't displayed from the standby file systems. I was able to find a different customer running 12.2(33)XNB which saw the same behavior. I couldn't find any cases where 12.2(33)XNC or later say the same behavior.
You may be able to get on the console of the standby RP and see its local file systems. You may need to enable the standby console though from the config of the active:
standby console enable
If not then I don't know of another way except to fail back over.
