  9. A Successfully imported installation message appears upon completion.

    The top half of the pop-up message contains a dark green background, a rectangular green logo with a capital P in white, and the text 'Pivotal Ops Manager' in white. The bottom half of the pop-up message contains a lighter green background, a round, dark green icon containing a light green check, and the text 'Successfully imported installation.' in dark green text.

Import New PAS and Product Tiles

After upgrading to Ops Manager v2.6, you must upgrade your product versions.

To upgrade your product versions:

  1. Import the product file to your Ops Manager Installation Dashboard.

  2. Hover over the product name in Available Products and click Add.

  3. Click the newly-added tile to review any configurable options.

  4. (Optional) If you use other service tiles, you can upgrade them following the same procedure. For more information, see Upgrading PAS and Other PCF Products.

Perform Your Upgrade

Warning: If the installation fails or returns errors, contact Support. Do not attempt to roll back the upgrade by restarting the previous version’s Ops Manager VM.

To perform your upgrade to Ops Manager v2.6:

  1. Navigate to the Ops Manager Installation Dashboard.

  2. Click Review Pending Changes, then Apply Changes. This immediately imports and applies upgrades to all tiles in a single transaction.

  3. Click each service tile, select the Status tab, and confirm that all VMs appear and are in good health.

  4. After confirming that the new installation functions correctly, remove the previous version’s Ops Manager VM.

(Optional) Task 3: Monitor Upgrade

The following sections describe how to monitor your PCF foundation during the upgrade and troubleshoot issues:

Check Status and Performance

You can monitor the progress of the upgrade by checking the status of the foundation at various locations.

Pivotal recommends live-monitoring your upgrade with PCF Healthwatch, which monitors and alerts on the current health, performance, and capacity of PCF. Healthwatch captures, calculates, stores, visualizes, and alerts on PCF platform metrics, including:

For more information, see the PCF Healthwatch documentation.

If you are not using PCF Healthwatch, you can do some or all of the following to monitor upgrade progress:

  • Use the BOSH CLI to check the status of a task, VM, or instance. For more information, see Check Status Using BOSH CLI.

  • Check app availability.

  • Run cf CLI commands.

  • Check the availability of the Ops Manager UI.

  • If using a network-attached storage (NAS) server, check the server’s performance.

  • If on vSphere, check vSphere performance.

Check Status Using BOSH CLI

To check the status of a task:

  1. Run:

    bosh -e ALIAS task TASK-NUMBER
    

    Where:

    • ALIAS is your BOSH alias.
    • TASK-NUMBER is the number of the upgrade task you want to check.

To check the status of a VM:

  1. Run:

    bosh -e ALIAS vms --vitals
    

    Where ALIAS is your BOSH alias.

To check the status of an instance:

  1. Run:

    bosh -e ALIAS instances --ps
    

    Where ALIAS is your BOSH alias.

Check Diego State

You can use the CF Diego Operator Toolkit (cfdot) to check Diego component instance count by current state. For more information, see the cfdot repository on GitHub.

Take Snapshots of Storage Metrics

You can periodically take snapshots of storage metrics. Pivotal recommends this if you have a large foundation and have experienced storage issues in the past.

Collect Logs

If you encounter problems during upgrade:

  1. Collect the following information:
    • All job logs
    • Task debug logs for VM upgrade tasks
    • The installation log from Ops Manager

This information helps determine the cause of upgrade issues.

Task 4: After Upgrade

The following sections describe how to prepare for use of your new environment, check its health status, and clean up after upgrading your PCF deployment:

Re-Create BOSH Alias

To log in to BOSH after upgrading PCF, you must re-create your alias.

To re-create your alias using BOSH:

  1. Run:

    bosh alias-env ALIAS -e DIRECTOR-IP
    

    Where:

    • ALIAS is the BOSH alias you are re-creating.
    • DIRECTOR-IP is the IP address of your BOSH Director VM.

Install New cf CLI

To install the version of the Cloud Foundry Command Line Interface (cf CLI) packaged with the PAS tile on Pivotal Network:

  1. Go to the Pivotal Application Service download page on Pivotal Network.

  2. Click the CF CLI download button.

  3. Unzip the cf CLI ZIP file containing compressed binaries for the cf CLI.

  4. Follow the procedure in the Install the cf CLI Using a Compressed Binary section of the Installing the cf CLI topic.

Check the Health of Your Deployment

Check the health of your PCF deployment to ensure that all jobs and processes are running as expected.

To check the health of your deployment:

  1. Check your system status by running:

    bosh -e ALIAS -d DEPLOYMENT-NAME instances --ps
    bosh -e ALIAS vms --vitals
    bosh -e ALIAS -d DEPLOYMENT-NAME cck --report
    

    Where:

    • ALIAS is your BOSH alias.
    • DEPLOYMENT-NAME is the name of your PCF deployment.
  2. Push and horizontally scale a test app to test PAS performance.

  3. If you are running PAS MySQL as a cluster, run the mysql-diag tool to validate health of the cluster. For more information, see the BOSH CLI v2 instructions in Running mysql-diag.

Check Resource Settings

If you added custom VM Type or Persistent Disk Type options, you must ensure that these values are correctly set and were not overwritten.

To check your custom resource settings:

  1. Go to the Ops Manager Installation Dashboard and click the Ops Manager tile.

  2. Select Resource Config.

  3. Ensure that the values for VM Type and Persistent Disk Type are correct.

Run BOSH Clean-Up

To clean up old stemcells, releases, orphaned disks, and other unused resources:

  1. Run:

    bosh -e ALIAS clean-up --all
    

    Where ALIAS is the BOSH alias you are re-creating.
