    Disaster Recovery

    Details disaster recovery behavior for NCS 1014, including CPU and chassis SSD replacement considerations, node restoration workflows, and backup ISO health checks that detect corruption and support recovery.

    Recovering nodes after chassis SSD replacement

    Describes how Cisco NCS 1014 recovers after chassis SSD replacement in operational and shutdown nodes, including backup, software, RPM, and configuration behavior.

    Backup ISO image health checks

    Explains how the health check feature audits the backup ISO image on Cisco NCS 1014 to support error-free booting during disaster recovery.

    CPU replacement considerations

CPU replacement considerations

CPU replacement behavior

You must consider these points for CPU replacement:

  • When the CPU is removed from the chassis, the NCS 1014 chassis runs in headless mode, which is non-traffic impacting.

  • When the CPU is replaced with another CPU that has the same software and RPMs as the chassis SSD, the configuration is restored from the chassis SSD.

  • When the CPU is replaced with another CPU that has different software and RPMs than the chassis SSD, the disaster recovery process starts. In this case, the node boots with the software from the chassis SSD, and the configuration is also restored from the chassis SSD.
