You must install node4 in the rack, transfer node2's connections to node4, boot node4, and install ONTAP. You must then reassign any of node2’s spare disks, any disks belonging to the root volume, and any non-root aggregates that were not relocated to node3 earlier in the process, as outlined in this section.

About this task

The relocation operation is paused at the beginning of this stage. This process is mostly automated; the operation pauses to enable you to check its status. You must manually resume the operation.

You need to netboot node4 if it does not have the same version of ONTAP 9 that is installed on node2. After you install node4, boot it from the ONTAP 9 image stored on the web server. You can then download the correct files to the boot media device for subsequent system boots, by following the instructions in Prepare for netboot.

Important:
Steps

  1. Make sure that node4 has sufficient rack space.

    If node4 is in a separate chassis from node2, you can put node4 in the same location as node3. If node2 and node4 are in the same chassis, then node4 is already in its appropriate rack location.

  2. Install node4 in the rack, following the instructions in the Installation and Setup Instructions for the node model.

  3. Cable node4, moving the connections from node2 to node4.

    Cable the following connections, using the instructions in the Installation and Setup Instructions or the FlexArray Virtualization Installation Requirements and Reference for the node4 platform, the appropriate disk shelf document, and High Availability management.

    Refer to References to link to the FlexArray Virtualization Installation Requirements and Reference and High Availability management.

    • Console (remote management port)

    • Cluster ports

    • Data ports

    • Cluster and node management ports

    • Storage

    • SAN configurations: iSCSI Ethernet and FC switch ports

      Note You might not need to move the interconnect card/FC-VI card or interconnect/FC-VI cable connection from node2 to node4 because most platform models have unique interconnect card models.
      For the MetroCluster configuration, you must move the FC-VI cable connections from node2 to node4. If the new host does not have an FC-VI card, you might need to move the FC-VI card.

  4. Turn on the power to node4, and then interrupt the boot process by pressing Ctrl-C at the console terminal to access the boot environment prompt.

    Note When you boot node4, you might see the following warning message: 
    WARNING: The battery is unfit to retain data during a power outage. This is likely
         because the battery is discharged but could be due to other temporary
         conditions.
         When the battery is ready, the boot process will complete
         and services will be engaged. To override this delay, press 'c' followed
         by 'Enter'

  5. If you see the warning message in Step 4, take the following actions:

    1. Check for any console messages that might indicate a problem other than a low NVRAM battery, and, if necessary, take any required corrective action.

    2. Allow the battery to charge and the boot process to complete.

      Warning Attention: Do not override the delay; failure to allow the battery to charge could result in a loss of data.
      Note Refer to Prepare for netboot.

  1. Configure the netboot connection by choosing one of the following actions.

    Note You must use the management port and IP as the netboot connection. Do not use a data LIF IP or a data outage might occur while the upgrade is being performed.
    If Dynamic Host Configuration Protocol (DHCP) is…​ Then…​

    Running

    Configure the connection automatically by using the following command at the boot environment prompt:

    ifconfig e0M -auto

    Not running

    Manually configure the connection by entering the following command at the boot environment prompt:
    ifconfig e0M -addr=filer_addr -mask=netmask -gw=gateway -dns=dns_addr -domain=dns_domain

    filer_addr is the IP address of the storage system (mandatory).
    netmask is the network mask of the storage system (mandatory).
    gateway is the gateway for the storage system (mandatory).
    dns_addr is the IP address of a name server on your network (optional).
    dns_domain is the DNS domain name (optional).

    Note Other parameters might be necessary for your interface. Enter help ifconfig at the firmware prompt for details.

  2. Perform netboot on node4:

    For…​ Then…​

    FAS/AFF8000 series systems

    netboot http://<web_server_ip/path_to_web-accessible_directory>/netboot/kernel

    All other systems

    netboot http://<web_server_ip/path_to_web-accessible_directory>/<ontap_version>_image.tgz

    The <path_to_the_web-accessible_directory> should lead to where you downloaded the <ontap_version>_image.tgz in Step 1 in the section Prepare for netboot.

    Note Do not interrupt the boot.

  3. From the boot menu, select option (7) Install new software first.

    This menu option downloads and installs the new ONTAP image to the boot device.

    Disregard the following message:

    This procedure is not supported for Non-Disruptive Upgrade on an HA pair

    The note applies to nondisruptive upgrades of ONTAP, and not upgrades of controllers.

    Note Always use netboot to update the new node to the desired image. If you use another method to install the image on the new controller, the incorrect image might install. This issue applies to all ONTAP releases. The netboot procedure combined with option (7) Install new software wipes the boot media and places the same ONTAP version on both image partitions.

  4. If you are prompted to continue the procedure, enter y, and when prompted for the package, enter the URL:

    http://<web_server_ip/path_to_web-accessible_directory>/<ontap_version>_image.tgz

  5. Complete the following substeps to reboot the controller module:

    1. Enter n to skip the backup recovery when you see the following prompt:

      Do you want to restore the backup configuration now? {y|n}

    2. Reboot by entering y when you see the following prompt:

      The node must be rebooted to start using the newly installed software. Do you want to reboot now? {y|n}

      The controller module reboots but stops at the boot menu because the boot device was reformatted, and the configuration data must be restored.

  6. Select maintenance mode 5 from the boot menu and enter y when you are prompted to continue with the boot.

  7. Verify that the controller and chassis are configured as HA:

    ha-config show

    The following example shows the output of the ha-config show command:

    Chassis HA configuration: ha
Controller HA configuration: ha
    Note System records in a PROM whether they are in an HA pair or stand-alone configuration. The state must be the same on all components within the stand-alone system or HA pair.

  8. If the controller and chassis are not configured as HA, use the following commands to correct the configuration:

    ha-config modify controller ha

    ha-config modify chassis ha

    If you have a MetroCluster configuration, use the following commands to modify the controller and chassis:

    ha-config modify controller mcc

    ha-config modify chassis mcc

  9. Exit maintenance mode:

    halt

    Interrupt AUTOBOOT by pressing Ctrl-C at the boot environment prompt.

  10. On node3, check the system date, time, and time zone:

    date

  11. On node4, check the date by using the following command at the boot environment prompt:

    show date

  12. If necessary, set the date on node4:

    set date mm/dd/yyyy

  13. On node4, check the time by using the following command at the boot environment prompt:

    show time

  14. If necessary, set the time on node4:

    set time hh:mm:ss

  15. In boot loader, set the partner system ID on node4:

    setenv partner-sysid node3_sysid

    For node4, partner-sysid must be that of node3.

    Save the settings:

    saveenv

  16. Verify the partner-sysid for node4:

    printenv partner-sysid

  17. Take one of the following actions:

    If your system…​ Then…​

    Has disks and no back-end storage

    Go to Step 23.

    Is a V-Series system or a system with FlexArray Virtualization software connected to storage arrays

    1. Go to section Set the FC or UTA/UTA2 configuration on node4 and complete the subsections in this section.

    2. Return to this section and complete the remaining steps, beginning with Step 23.

    Important You must reconfigure FC onboard ports, CNA onboard ports, and CNA cards before you boot ONTAP on the V-Series or system with FlexArray Virtualization software.

  1. Add the FC initiator ports of the new node to the switch zones.

    If your system has a tape SAN, then you need zoning for the initiators. If required, modify the onboard ports to initiator by referring to the Configure FC ports on node4. See your storage array and zoning documentation for further instructions on zoning.

  2. Add the FC initiator ports to the storage array as new hosts, mapping the array LUNs to the new hosts.

    See your storage array and zoning documentation for instructions.

  3. Modify the worldwide port name (WWPN) values in the host or volume groups associated with array LUNs on the storage array.

    Installing a new controller module changes the WWPN values associated with each onboard FC port.

  4. If your configuration uses switch-based zoning, adjust the zoning to reflect the new WWPN values.

  1. If you have NetApp Storage Encryption (NSE) drives installed, perform the following steps.

    Note If you have not already done so earlier in the procedure, see the Knowledge Base article How to tell if a drive is FIPS certified to determine the type of self-encrypting drives that are in use.

    1. Set bootarg.storageencryption.support to true or false.

      If the following drives are in use… Then…

      NSE drives that conform to FIPS 140-2 Level 2 self-encryption requirements

      setenv bootarg.storageencryption.support true

      NetApp non-FIPS SEDs

      setenv bootarg.storageencryption.support false
      Note

      You cannot mix FIPS drives with other types of drives on the same node or HA pair.
      You can mix SEDs with non-encrypting drives on the same node or HA pair.

    2. Go to the special boot menu and select option (10) Set Onboard Key Manager recovery secrets.

      Enter the passphrase and the backup information that you recorded earlier procedure. See Manage storage encryption using the Onboard Key Manager.

  2. Boot node into boot menu:

    boot_ontap menu

    If you do not have an FC or UTA/UTA2 configuration, execute Check and configure UTA/UTA2 ports on node4, Step 15 so that node4 can recognize node2's disks.

  3. For MetroCluster configuration, V-Series systems and systems with FlexArray Virtualization software connected to storage arrays you must set and configure the FC or UTA/UTA2 ports on node4 to detect the disks attached to the node.
    To complete this task, go to section Set the FC or UTA/UT2 configuration on node4.
