After you update UMDS, you can proceed with updating the management ESXi hosts in Region A. You use vSphere Update Manager for automated host update across the management cluster.

Use different baseline types аccording to the storage type, vSAN or traditional, that you use in the management cluster for Region A.

Note:

vSAN Witness Host Appliance

Prerequisites

  • Verify that the system hardware complies with the following areas of the ESXi requirements. See VMware Compatibility Guide.

    • System compatibility

    • I/O compatibility with network and host bus adapter (HBA) cards

    • Storage compatibility

    • Backup software compatibility

    • Compatibility of the firmware for the network and host bus adapter (HBA) cards. Upgrade the firmware accordingly.

    • BIOS compatibility. Upgrade the BIOS on the ESXi hosts accordingly.

  • Allocate sufficient disk space on the host for the upgrade.
  • To have management workloads automatically migrated from hosts while they are being upgraded, verify that vSphere DRS on the management cluster is set to Fully Automated for the duration of the upgrade operations.

  • If using vSAN in the management cluster, on the Monitor tab for the cluster in the vSphere Web Client, verify that these properties have the following values:

    • The vSAN > Health report indicates that the checks for the cluster, network, physical disk, data, limits, hardware compatibility, performance service, and online health are passed.

    • The vSAN > Resyncing Components report shows no Resyncing Components and Bytes left to resync.

    • The vSAN > Physical Disks report shows that the disks on all hosts in the cluster are in mounted state and their vSAN health status is healthy.

  • If using Stretched vSAN in the management cluster, in addition to the above, on the Monitor tab for the cluster in the vSphere Web Client, verify that these properties have the following values:

    • The vSAN > Health > Stretched cluster report indicates that the checks for the site latency, witness host not found, witness house fault domain misconfigured, whitness hose within vCenter cluster are passed.

What to do next

  • Verify that the management ESXi hosts are operational after the upgrade.
