Retire node1

Contributors netapp-pcarriga netapp-martyh

To retire node1, resume the automated operation to disable the HA pair with node2 and shut down node1 correctly. You must later remove the AFF A700 controller module and the NVRAM module from the node1 chassis and then install the AFF A900 NVRAM module and controller module on node1.

Steps
  1. Resume the operation:

    system controller replace resume

  2. Verify that node1 has been halted:

    system controller replace show-details

    After node1 has completely halted, node1 should be at the LOADER> prompt. To see the LOADER> prompt, connect to the serial console of node1.

Remove the AFF A700 controller module and NVRAM module

At this stage, node1 is down and all data is served by node2. Because node1 and node2 are in the same chassis and powered by the same set of power supplies, do NOT power off the chassis. You must take care to remove only the node1 controller module and the node1 NVRAM module. Typically, node1 is controller A, located on the left side of the chassis when looking at the controllers from the rear of the system. The controller label is located on the chassis directly above the controller module.

Before you begin

If you are not already grounded, correctly ground yourself.

Remove the AFF A700 controller module

Use the following procedure to remove the AFF A700 controller module.

Steps
  1. Detach the console cable, if any, and the management cable from the node1 controller module before removing the controller module from node1.

    Warning When you are working on node1, you only remove the console and e0M cables from node1. You must not remove or change any other cables or connections on either node1 or node2 during this process.
  2. Unlock and remove the controller module A from the chassis.

    1. Slide the orange button on the cam handle downward until it unlocks.

      Remove controller module
      Number one

      Cam handle release button

      Number two

      Cam handle

    2. Rotate the cam handle so that it completely disengages the controller module from the chassis, and then slide the controller module out of the chassis.

      Make sure that you support the bottom of the controller module as you slide it out of the chassis.

Remove the AFF A700 NVRAM module

Use the following procedure to remove the AFF A700 NVRAM module.

Note The AFF A700 NVRAM module is in slot 6 and is double the height of the other modules in the system.
Steps
  1. Unlock and remove the NVRAM module from slot 6 of node1.

    1. Depress the lettered and numbered cam button.

      The cam button moves away from the chassis.

    2. Rotate the cam latch down until it is in a horizontal position.

      The NVRAM module disengages from the chassis and moves a few inches.

    3. Remove the NVRAM module from the chassis by pulling on the pull tabs on the sides of the module face.

      Remove the NVRAM module
      Number one

      Lettered and numbered I/O cam latch

      Number two

      I/O latch completely unlocked

  2. If you are using any add-on modules as coredump devices on the AFF A700 NVRAM module, do NOT transfer them to the AFF A900 NVRAM module.

Install the AFF A900 NVRAM module and controller module on node1

You must install the AFF A900 NVRAM module and controller module that you received for the upgrade on node1. Do NOT move the coredump devices from the AFF A700 NVRAM module to the AFF A900 NVRAM module.

Before you begin

If you are not already grounded, correctly ground yourself.

Install the AFF A900 NVRAM module

Use the following procedure to install the AFF A900 NVRAM module in slot 6 of node1.

Steps
  1. Align the NVRAM module with the edges of the chassis opening in slot 6.

  2. Gently slide the NVRAM module into the slot until the lettered and numbered I/O cam latch begins to engage with the I/O cam pin, and then push the I/O cam latch all the way up to lock the NVRAM module in place.

    Install the NVRAM module
    Number one

    Lettered and numbered I/O cam latch

    Number two

    I/O latch completely unlocked

Install the AFF A900 controller module on node1.

Use the following procedure to install the AFF A900 controller module in node1.

Steps
  1. Align the end of the controller module with opening A in the chassis, and then gently push the controller module halfway into the system.

    Note Do not completely insert the controller module in the chassis until instructed to do so later in the procedure.
  2. Cable the management and console ports to the node1 controller module.

    Note Because the chassis is already powered ON, node1 starts BIOS initialization followed by autoboot as soon as it is fully seated. To interrupt the node1 boot, before completely inserting the controller module into the slot, it is recommended that you connect the serial console and management cables to the node1 controller module.
  3. Firmly push the controller module into the chassis until it meets the midplane and is fully seated.

    The locking latch rises when the controller module is fully seated.

    Warning To avoid damaging the connectors, do not use excessive force when sliding the controller module into the chassis.
    Install the controller module
    Number one

    Cam handle locking latch

    Number two

    Cam handle in the unlocked position

  4. Connect the serial console as soon as the module is seated and be ready to interrupt AUTOBOOT of node1.

  5. After you interrupt AUTOBOOT, node1 stops at the LOADER prompt. If you do not interrupt AUTOBOOT on time and node1 starts booting, wait for the prompt and press Ctrl-C to go into the boot menu. After the node stops at the boot menu, use option 8 to reboot the node and interrupt the AUTOBOOT during reboot.

  6. At the LOADER> prompt of node1, set the default environment variables:

    set-defaults

  7. Save the default environment variables settings:

    saveenv
