Upgrade Dell PowerFlex to v3.6.x

Upgrading a PowerFlex two-layer system

Upgrade a two-layer PowerFlex system to the latest version.

1. Edit the following file:
   /opt/emc/scaleio/gateway/webapps/ROOT/WEB-INF/classes/gatewayUser.properties
2. Add the complete list of SDC IP addresses to im.ip.ignore.list.
3. Restart the PowerFlex Gateway:

   /etc/init.d/scaleio-gateway restart

4. Upgrade the Linux-based PowerFlex Gateway:

   rpm -U EMC-ScaleIO-gateway-3.6-X.<build>.x86_64.rpm 

   The following variables can be added to the command, if required:

   • SIO_GW_KEYTOOL=<keytool_path> allows override of the location for the Java keytool utility. For example: SIO_GW_KEYTOOL=/usr/java/jre1.8.0_XX/bin/
   • SIO_JAVA=<Java version> specifies a different Java version

   Example:

   rpm -U /tmp/EMC-ScaleIO-gateway-3.6-X.<build>.x86_64.rpm

   A success message is displayed, and the PowerFlex Installer has been updated to the new version. Log in to the updated PowerFlex Installer will be required.
5. Log in to the PowerFlex Installer (In a web browser, go to https://<PowerFlex Gateway_IP_ADDRESS>).
6. Click Packages.

   You may need to re-authenticate with your login credentials. The Manage Installation Packages window appears.

   NOTE:When using the PowerFlex Installer to install packages for Windows and Linux, you can upload all the files at once.
7. Browse to the package locations for the operating systems of the nodes that you want to upgrade.
8. Select all the relevant files for the operating systems of the nodes which you want to upgrade. Both your current version and the target version to which you are upgrading are required.
   File formats can be RPM, TAR, or MSI. Minimally, you must select these packages:
   1. MDM
   2. SDS
   3. SDC
   4. LIA
      The Browse button changes its appearance to reflect the selected files.

   Packages from the current version: lia, mdm, sds, sdc, xcache (optional), sdr (optional). For example:

   • EMC-ScaleIO-lia-3.0.x-XXX.<build>.<flavor>.x86_64.rpm
   • EMC-ScaleIO-mdm-3.0.x-XXX.<build>.<flavor>.x86_64.rpm

   Packages from target version: lia, mdm, sds, sdc, xcache (optional), sdr (optional). For example:

   • EMC-ScaleIO-lia-3.6-X.<build>.<flavor>.x86_64.rpm
   • EMC-ScaleIO-mdm-3.6-X.<build>.<flavor>.x86_64.rpm
9. When all files are selected, click Open.
10. Click Upload.

    The uploaded installation packages (RHEL, in this example) are listed in the file table.

11. Upgrade the PowerFlex components:
    1. From the PowerFlex Installer, click the Maintain tab.
    2. From the Maintenance operation screen, perform the following:
       1. Type the primary MDM's credentials.
       2. Type the LIA password (upgrades from versions prior to v3.0 only allow native authentication for LIA).
       3. Click Retrieve system topology. A success message is displayed.
       4. Click Upgrade.

          The Device Media Type for PowerFlex system window is displayed.

    3. Select the device media type (mandatory) and external acceleration type (optional) for each Storage Pool in the system, and then click Proceed.
       For external acceleration, options include:

       • none—No devices are accelerated by a non-PowerFlex read or write cache
       • read—All devices are accelerated by a non-PowerFlex read cache
       • write—All devices are accelerated by a non-PowerFlex write cache
       • read_and_write—All devices are accelerated by both non-PowerFlex read and write cache

       This input is required in order to prevent the generation of false alerts for media type mismatches. For example, if an HDD device is added which the SDS perceives as being too fast to fit the HDD criteria, alerts might be generated. External acceleration/caching is explained in the Getting to Know Dell PowerFlex Guide.

    4. Set upgrade options:
       • To prevent upgrade of SDCs, select Do not upgrade any SDCs. You might want to use this option if the SDCs are running critical applications that are currently in use. You can upgrade the SDCs later.
       • To continue an upgrade that was interrupted on a different gateway, select Allow upgrade even when already in Upgrade state.

         Use this option when you started an upgrade using a different gateway, but that gateway failed or is offline now.

       • Set performance profiles.

         High performance profiles are mandatory when using Fine Granularity Storage Pools. For other configurations, they are optional. You can modify these profiles later.

       • Perform automatic restart of Windows-based servers (required for Windows-based nodes on which SDCs are deployed).
       • To upgrade SDSs in the same Fault Set together, select Allow parallel SDS upgrades.

         Parallel upgrade of SDSs in the same Fault Set saves time; the upgrade will be performed faster.

    5. Confirm the upgrade operation by typing the MDM admin password, and click Upgrade.
       NOTE:If a certificate notice is displayed, review and approve it.
    6. Click the Monitor tab, and approve each step of the upgrade process.
    7. When the upgrade is complete, click Mark operation completed.
12. The following steps involve restarting the SDC node, which might cause I/O failures. It is recommended to migrate VMs before starting.
13. Remove the old plug-in:
    1. From the folder where you extracted the EMC-ScaleIO-vSphere-plugin-installer-3.6-X.<build>.X.zip file, use PowerCLI to run the VxFlexOSPluginSetup.ps1 script.
    2. Select option 2, Unregister ScaleIO plugin.
    3. Enter the vCenter credentials and confirm the script actions.
    4. Log out, then log back in to the vSphere web client.
       The plug-in is no longer registered.
14. Register the new plug-in, as described in the "Register the new plug-in" topic.
15. Upgrade SDCs on the ESXi-based nodes, as described in the "Upgrade and restart the SDCs" topic.
    This step requires restarting the SDC node, which may cause I/O failures. It is recommended to migrate VMs before starting.
