Flash Disk Recovery
When an RSP is power cycled or experiences an ungraceful reset, the boot disk (PCMCIA flash disk used to
boot the card) may experience a file-system corruption. If this occurs, an error message is displayed and the
RSP fails to boot. The corrupted flash disk is automatically reformatted and the Cisco IOS XR software is
restored from the designated system controller (DSC) for the system.
For example, if a flash disk for an RSP is corrupted, the RP fails to boot and the following error message is
displayed:
