    Disk0 on RE0 is having error.

    The device has booted from secondary disk.

    Try this to take a snapshot from secondary to primary disk.

    request vmhost snapshot recovery

     

    recovery(Optional) Recover the primary disk from the snapshot content stored in the backup disk. This option is applicable only when the Routing engine is booted from backup disk. Contents in the primary disk are lost.
