    Converting a Multichassis System Into Two Single Chassis

    Use this procedure to convert a multichassis system into two single chassis.

    Note: This procedure is service-affecting on the satellite chassis. Traffic will be affected. There is no rollback.

    Caution: We recommend that you perform this procedure in a maintenance window. If this procedure is incorrectly followed, you might bring the hub chassis into a state that can only be recovered by a system repair drive.

    1. Log in to the CLI using the shared management IP address.
    2. Back up the existing configuration and save a snapshot of the state of the multichassis system.
      1. Save the configuration database to a remote location.

        For example:

        bti7800# system database backup remote-url ftp://john@10.64.7.51 Value for 'password' (<string>): *********** bti7800# show system database Backup Status ------------- CurrentStatus : ready-to-backup RemoteUrl : ftp://john@10.64.7.51/10.1.220.104_BTI7800v1.6.0_18346_20150706_185955.tar.gz NotificationMsg : Backup successful

        Look for the Backup successful message in the output.

      2. Save the running configuration to a remote location.

        For example:

        bti7800# show running-config | nomore | save 10.1.220.104_running_config_20150706 Value for 'password' (<string>): *********** bti7800# copy file 10.1.220.104_running_config_20150706 remote-url ftp://john@10.64.7.51/10.1.220.104_running_config_20150706 Value for 'password' (<string>):
      3. Save the state information to a remote location.

        For example:

        bti7800# show tech-support remote-url ftp://john@10.64.7.51 Value for 'password' (<string>): Searching Inventory..................................Done Exploring data at Chassis:1 Collecting data from pld:1/2....Done Collecting data from pld:1/5....Done Collecting data from pld:1/8....Done Collecting data from pld:1/10....Done Collecting data from pld:1/11....Done Collecting data from pld:1/13....Done Collecting data from cmm:1/A....Done Creating archive..Done Transferring file.... 10.1.220.104_chassis-1_tech-support_2015-07-06_19-30-32.tar.gz transferred successfully!
    3. Disconnect the inter-chassis cables.

      You might see an alarm indicating a cable is disconnected.

    4. Remove the satellite chassis from the system.
      bti7800# show system chassis Serial-Number Chassis ID ---------------- ---------- 2413CR-010 1 2413CR-011 2 bti7800# config bti7800(config)# no system chassis 2413CR-011 bti7800(config)# commit Commit complete.

      Caution: If you remove the hub chassis by mistake, the hub chassis will go into a state that can only be recovered by a system repair drive.

      The hub chassis is now a single chassis system.

    5. Perform a software installation using a system repair drive on both CMMs in the satellite chassis.

      For details on how to do this, see Restoring a System from a System Repair Drive.

    Both chassis are now single chassis systems.
