    Performing an offline data in place conversion

    Starting the offline 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 synchronous replication sessions on the replication source array:
      • In Unisphere, navigate to Protection & Mobility > Replication.
      • Select the synchronous replication session, then click More Actions > Pause.
      • Wait for Unisphere to pause the selected replication session.
      • Pause any remaining synchronous replication sessions.
      • Click Refresh to verify that all synchronous replication sessions are paused.
    • 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 Offline 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.
      4. Review the Summary screen and ensure that the information displayed is correct.
      The wizard halts the system.
    4. Wait for the wizard to halt the system before continuing.
      To ensure that the system is halted, check that the fault and power lights on both SPs are off, and that the amber fault LEDs on both power supplies are lit. The solid green AC/DC power indicator LED will still be lit on the power supplies.

    Preparing the SP assemblies for offline hardware upgrade

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

    Before you begin

    Ensure that the fault and power lights on both SPs are off, and that the amber fault LEDs on both power supplies are lit. This indicates that both SP assemblies have been halted successfully. The solid green AC/DC power indicator LED will still be lit on the power supplies.

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

    Procedure
    1. Remove power cables from both SP assemblies.
    2. Wait for the disk processor enclosure (DPE) 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 SP B, then remove all cables from the system.
      • 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.
      Figure 2. Cable clamp with labels

      Cable clamp may or may not include numbering.

      After performing the conversion, be sure to reinsert the cables, I/O modules, and CNA SFPs in the same configuration after the new SP assembly is inserted, using the labels on the cable clamps as a guide. It is recommended that you upgrade one SP assembly at a time to avoid reinserting parts into the wrong SP assembly.

    Removing SP assembly B

    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 is opposite of 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 are properly labeled using the cable clamps, and removed from the storage processor assembly.

    Procedure
    1. Pull the torque limit screw handle out of SP assembly B (1).
    2. Turn the handle counterclockwise to release SP assembly B 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 SP assembly B

    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. 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.
    3. 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.

    Completing the offline hardware upgrade

    Insert the power cables and complete the Hardware Upgrade wizard in Unisphere to finish the Data in Place conversion.

    Before you begin

    Ensure that you have performed the physical swap of both storage processor assemblies. Check that all cables, power supplies, I/O modules and CNA adaptors are in their proper location.

    Once the upgrade is complete, it is no longer possible to revert to the old SP assembly. The Data in Place conversion process can be canceled at any point before restarting the system with the new SPs. For more information about canceling the upgrade, see Canceling the Data in Place conversion
    Procedure
    1. Insert power cables for both SP A and SP B to power on the system.
    2. Wait for the system to power on and complete the upgrade.
      The system may take up to 120 minutes to restart. The SP Fault LEDs blink blue while the system is restarting, and turns off when the system has restarted.

    3. Unisphere times out, closing the Hardware Upgrade. To verify that the upgrade was successful, log back into Unisphere after the system has restarted, and confirm that the new model number on the System View page matches the new hardware model number.
      The wizard will not complete if the new SP assembly is not functional, and the old SPs must be returned to the system. If the wizard does not complete, or states that the upgrade failed, troubleshoot the problem using the information in Troubleshooting and check for hardware faults.
    4. Place the corresponding new part number sticker over the Product Serial Number Tag (PSNT) part number field, and change the model field to match the new hardware.
      Refer to Upgrade conversion worksheet for part numbers of new hardware.

      After a data in place conversion, the Performance dashboard in Unisphere resets and may appear blank until new data is collected. If you require historical data from the dashboard, refer to KB article 519081 and call support.

    Verifying the new storage processor assembly

    Verify that the new storage processor assembly is recognized by your system, and operating correctly using the procedure that follows.
    Procedure
    1. In Unisphere, select System View.
    2. On the Summary page, confirm that the system status is OK.
    3. Select the Enclosures page.
    4. Verify that the storage processor assembly appears with OK status in the enclosure view.
      You may need to refresh Unisphere by clicking on the refresh icon next to the Enclosures view.

      Select the DPE in the Enclosure dropdown menu and select the Rear view of the enclosure. Select the new storage processor shown in this enclosure view.

      If the system health monitor shows the part as faulted, contact your service provider.

    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.
    Enable Secure Shell (SSH) on the system

    By default, the Secure Shell (SSH) protocol is disabled after an offline upgrade. To connect to the system and perform advanced system maintenance, you need to enable SSH on the storage system. This service action allows you to run service tools, such as service actions or service scripts, on the storage system. Once SSH is enabled, you or your service provider can run the tools through a service portal. When the service tools have finished running, disable the SSH protocol to ensure the system is secure.

    Follow these steps to enable SSH:

    1. In Unisphere, select Service > Service Tasks > Enable SSH.
    2. Select Execute.
    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.
