If you are using multiple availability zones in Region A, to remediate the hosts in the cluster, use the system managed baseline automatically created in vSphere Update Manager on the Management vCenter Server in Region A. Apply the baseline according to a specific order of operations.

Upgrading the hosts in the management cluster in Region A when using a multiple availability zone configuration on top of a vSAN stretched cluster requires the following order:

  1. Upgrade the ESXi hosts in Availability Zone 1.

  2. Upgrade the ESXi hosts in Availability Zone 2.

  3. Upgrade the vSAN witness host appliance.

  4. Upgrade any hardware components to ensure compatibility with vSAN 6.6.x.

Procedure

  1. Log in to vCenter Server by using the vSphere Web Client.
    1. Open a Web browser and go to https://sfo01m01vc01.sfo01.rainpole.local/vsphere-client.
    2. Log in using the following credentials.

      Setting

      Value

      User name

      administrator@vsphere.local

      Password

      vsphere_admin_password

  2. Verify that the vSAN Build Recommendation Engine is healthy using your my.vmware.com credentials to download the latest recommendation from VMware.
    1. From the Home menu of the vSphere Web Client, select Hosts and Clusters.
    2. In the Navigator, expand the sfo01m01vc01.sfo01.rainpole.local > sfo01-m01dc > sfo01m01-mgmt01 tree.
    3. On the Monitor tab, click the vSAN tab and select Health.
    4. Expand the vSAN Build Recommendation test name.
    5. Click the vSAN Build Recommendation Engine Health test name, and click the Login to my.vmware.com button.
    6. In the Login dialog box, enter the following settings and click OK.

      Setting

      Value

      Username

      my.vmware.com_account_name

      Password

      my.vmware.com_account_password

  3. Verify that the system managed baseline for upgrade of vSAN-backed hosts is available in vSphere Update Manager in Region A .
    1. From the Home menu, select Update Manager.
    2. In the left Servers pane, click sfo01m01vc01.sfo01.rainpole.local.
    3. In the right pane, on the Manage tab, click Hosts Baselines.
    4. In the Baseline Group pane, expand the System managed group and verify that the VSAN Cluster 'sfo01-m01-mgmt01' baseline group contains the VMware ESXi 6.5.0 U2 (vSAN 6.6.1 Update 2 build xxxxxx) host update baseline.
  4. Scan the cluster for updates against the system managed baseline.
    1. In the Hosts Baselines pane, click the Go to compliance view button to locate the sfo01-m01-mgmt01 cluster in the inventory.
    2. Move up the inventory tree in the Navigator pane, and select sfo01-m01dc.

      In the data center object you access the hosts in Availability Zone 1, Availability Zone 2 and the vSAN witness host. If you use the cluster object in the vSphere Web Client, you access only Availability Zone 1 and Availability Zone 2.

    3. On the Update Manager tab, click the Scan for Updates button.
    4. In the Scan for Updates dialog box, under Scan hosts for, select Patches and Extensions and Upgrades , and click OK.

      After the scan is complete, the cluster state is Non-Compliant.

  5. Remediate the hosts in Availability Zone 1 of the stretched vSAN cluster and upgrade to vSphere 6.5 Update 2.
    1. On the Update Manager tab, click Remediate.
    2. On the Select baselines page of the Remediate wizard, in the Baselines Groups and Types pane, select the VSAN Cluster 'sfo01-m01-mgmt01' baseline group, verify that all baselines in the Baselines pane are selected, and click Next.
    3. On the Select target objects page, select all of the management hosts in that reside in Availability Zone 1 and click Next.
    4. On the Patches and extensions page, ensure that VMware ESXi 6.5 Complete Update 2 is selected together with any recommended extensions and click Next.
    5. On the Advanced options page, click Next
    6. On the Host remediation options page, deselect Retry entering maintenance mode in case of failure and click Next.
    7. On the Cluster remediation options page, select the following options and click Next.

      Setting

      Value

      Disable Distributed Power Management (DPM) if it is enabled for any of the selected clusters

      Selected

      Disable High Availability admission control if it is enabled for any of the selected clusters

      Selected

      Enable parallel remediation for the hosts in the selected clusters > Automatically determine the maximum number of concurrently remediated hosts in a cluster

      Selected

      Migrate powered off or suspended VMs to other hosts in the cluster, if a host must enter maintenance mode

      Selected

    8. On the Ready to complete page, click Pre-check Remediation to generate a pre-upgrade report about any identifiable problems that would prevent a successful upgrade.

      Address any items reported in the Pre-check Remediation dialog box before you proceed with the upgrade and click OK.

      If the Disable HA admission control message from Recommended Changes is displayed, ignore it.

    9. After you address all pre-check items, click Finish to begin the upgrade.
  6. After the hosts in Availability Zone 1 are remediated, repeat Step 5 on the hosts in Availability Zone 2.
  7. After the hosts in both Availability Zone 1 and Availability Zone 2 are remediated, update the vSAN witness host.

    The vSAN witness host appears as light-blue in the list of target objects.

  8. After all ESXi hosts are upgraded to the latest version, review the NSX status of the management cluster.
    1. Select Home > Networking & Security.
    2. Select Installation and Upgrade in the Navigator.
    3. On the Host Preparation tab, select 172.16.11.65 from the NSX Manager menu and verify that Installation Status for all management ESXi hosts is green.
  9. Review the Hardware Compatibility status of the management cluster.
    1. From the Home menu, select Hosts and Clusters.
    2. In the Navigator, expand the sfo01m01vc01.sfo01.rainpole.local > sfo01-m01dc > sfo01m01-mgmt01 tree.
    3. On the Monitor tab, click vSAN tab and select Health.
    4. Locate and verify that the Hardware compatibility tests have passed.
    5. If a Warning test result is present, expand the Hardware compatibility tests, review individual tests for a Warning test result, and perform the following troubleshooting.
