    Performing the online data in place conversion

    Starting the online hardware upgrade

    The upgrade procedure must begin in Unisphere before the physical hardware swap can occur.

    Before you begin
    Due to ETA 518863, the minimum required operating environment is Unity OE 4.3.1 or later. When possible, upgrade to the latest code available before starting the data in place conversion.
    • Pause all replication sessions on the replication source array:
      • In Unisphere, navigate to Protection & Mobility > Replication.
      • Select the replication session, then click More Actions > Pause.
      • Wait for Unisphere to pause the selected replication session.
      • Pause any remaining replication sessions.
      • Click Refresh to verify that all replication sessions are paused.
    • Ensure that the combined CPU utilization is below 120%.
    • Verify the model number of the new system, located on the replacement SP's packaging.
    • Working with hardware may cause electrostatic discharge that could damage your hardware. Before working with any hardware, review the precautions when removing or replacing components.
    Procedure
    1. In Unisphere, select Service, then Service Tasks.
    2. Select Hardware Upgrade, then Execute.
    3. Complete the Hardware Upgrade wizard.
      1. Select Online storage processor upgrade.
        If you are unsure of which upgrade method to pick, review the considerations in Choosing an offline or an online conversion before proceeding.
      2. Select the target upgrade model from the list.
      3. Perform a pre-upgrade health check (PUHC) to ensure the system is healthy before proceeding.
        Refer to Troubleshooting for more information on failed pre-upgrade health checks.
      4. Review the Summary screen and ensure that the information displayed is correct.
      The wizard halts the storage processor assembly.
    4. Wait for the wizard to halt the SP before continuing.
      The wizard directs you to replace either SP A or SP B. Follow the instructions in the wizard to replace the correct SP.
      To ensure that the SP is halted, check that the fault and power lights on the SP are off, and that the amber fault LEDs on the power supply is lit. Do not remove an SP while the Unsafe to remove SP LED (3) is lit.

    Preparing the SP assemblies for online upgrade

    Follow these tasks before removing the SP assembly to ensure that the upgrade is successful.

    Before you begin

    To ensure that the storage processor assembly is halted, check that the SP fault and power LEDs are both off. This indicates that the SP assembly has been halted successfully. The power supply power LED remains green. Management Ethernet connection LEDs also remain lit.

    DO NOT REMOVE an SP assembly while the "Unsafe to remove SP" LED shown below is lit.

    The Data in Place conversion process can be canceled at any point before replacing the first SP. To cancel the upgrade, re-seat the original SP by pulling the SP out an inch or so, and then reinsert it. For more information about cancelling the upgrade, see Canceling the Data in Place conversion.
    Procedure
    1. Remove the power cable from the SP indicated in the Hardware Upgrade wizard in Unisphere.
      Leave all cables plugged into the other SP while replacing this SP.
    2. Wait for the SP to power off before continuing.
    3. Place the provided cable clamps onto all front- and back-end cables, including the I/O modules, CNA ports, and onboard ports of the SP, then remove all cables from the SP.
      • Clearly mark all cable clamps with meaningful and detailed information about where cables connect, which aids in re-connection following the conversion process.
      • All front- and back-end cables that connect to an I/O module in a slot use one cable clamp.
      • All cable clamps will be used for both SP assemblies.
      • Ensure that all cables are set into the grooves in the cable clamp as seen in the illustration below, and that no cables are pinched in the space between the grooves.

    Removing the first SP assembly

    This procedure describes how to remove SP assembly B from the enclosure. There are two SP assemblies: SP A and SP B. The top SP assembly is SP B, and mirrors the bottom SP assembly, SP A. The illustration shows removal of SP assembly B. The procedure for removing SP assembly A is the same.

    Before you begin

    Ensure that all cables attached to the SP assembly to be replaced are properly labeled using the cable clamps, and removed from the SP assembly. Only replace the SP assembly that is indicated in the Hardware Upgrade wizard in Unisphere.

    Procedure
    1. Pull the torque limit screw handle out of the SP assembly (1).
    2. Turn the handle counterclockwise to release the SP assembly from the enclosure (1). As the handle is turned, the SP assembly extracts out of the enclosure. When outward movement stops, the SP assembly is ready for removal.
      The SP assembly is heavy. Exercise caution when removing the SP assembly to avoid personal injury and/or damage to the equipment.
      Figure 4. Remove an SP assembly
    3. Use the handle to pull the SP assembly outward enough to grasp the sides with both hands (2). Then with both hands supporting the SP assembly, pull the SP assembly fully out of the enclosure.
    4. Place the SP assembly on a clean, flat static-free work surface.

    Installing the new SP assembly

    Install the new SP assembly to complete the physical hardware swap.

    Procedure
    1. Align the SP assembly with the enclosure slot and slide it into the slot until it stops (1).
    2. If the conversion kit shipped with extra power supplies, install the new power supply.
      Do not transfer the power supply in the next step if you install a new power supply.
      All data in place All-Flash Array (AFA) conversions from a Unity x00F series to a Unity x50F series include two new power supplies. Review KB 520323 for additional information if you did not receive new power supplies for this specific type of conversion.
    3. Transfer each I/O module, CNA SFP and power supply from the old SP into the same location on the new SP.
      Documentation with detailed steps for removing and installing customer replaceable units, such as I/O modules, CNA SFPs, and power supplies, is available on https://support.emc.com/products/39949.
    4. Connect each I/O module cable, CNA cable and onboard cable into the same port from which it was removed.
    5. Turn the orange torque limit screw handle clockwise until you hear a click sound from the handle (1). The click sound indicates the torque limit is reached and the SP assembly is seated in the enclosure.
    6. Push the orange torque limit screw handle into the SP assembly until you hear a click sound from the handle (2). The click sound indicates screw handle is secured in the assembly.

    Post-upgrade tasks

    Complete these tasks after successfully upgrading the storage processor assemblies.

    Completing the upgrade conversion worksheet

    It is important that you complete the upgrade conversion worksheet to ensure that we receive the new product number of your system. Refer to Update install base records .

    Changing the array name field

    Your array has both a Model field and a Name field. The model name updates automatically after the conversion is completed, but the Name field does not change. When the array is first installed, the Name field defaults to the array serial number, however the name of the array can be customized by the owner. If the conversion requires the array name to be altered, you can change the Name field at any time.

    Follow these steps to change the name field:

    1. In Unisphere, select the gear icon in the top right of the dashboard.
    2. Select Management, then Unisphere IPs.
    3. Type a new name for the system in the Name field, then select Apply to save the changes.
    4. Confirm that the name change is reflected in System > System View > Summary.
    Disposal of the original storage processor assemblies

    The two storage processor assemblies that were removed from your array belong to you, but can no longer be used with the upgraded system. Contact your local recycling center for instructions on how to dispose of the hardware. Dell EMC is not responsible for the pick up or disposal of old hardware.

    Internal disks may contain sensitive data. Be sure to remove the disks and securely dispose of them before recycling the rest of the SP.
