Manual Error Recovery

If an error is detected during the upgrade, ISSU is aborted. In this case, the recommended procedure is to reload the stack to the old or new image from the primary or secondary partition, and then use the boot system flash command to reload the stack.

Complete the following steps to manually recover from an ISSU error.

  1. Reload to the primary partition. 
    device# boot system flash primary
  2. Reload to the secondary partition. 
    device# boot system flash secondary
