VMware Cloud Foundation 4.5 Release Notes

Parallel upgrades of vCenter Server are not supported

If you attempt to upgrade vCenter Server for multiple VI workload domains at the same time, the upgrade may fail while changing the permissions for the vpostgres configuration directory in the appliance. The message chown -R vpostgres:vpgmongrp /storage/archive/vpostgres appears in the PatchRunner.log file on the vCenter Server Appliance.

Workaround: Each vCenter Server instance must be upgraded separately.

Performing parallel prechecks on multiple workload domains that use vSphere Lifecycle Manager images may fail

If you perform parallel prechecks on multiple workload domains that use vSphere Lifecycle Manager images at the same time as you are peforming parallel upgrades, the prechecks may fail.

Workaround: Use the following guidance to plan your upgrades and prechecks for workload domains that use vSphere Lifecycle Manager images.

For parallel upgrades, VMware Cloud Foundation supports up to five workload domains with up to five clusters each.
For parallel prechecks, VMware Cloud Foundation supports up to three workload domains with up to four clusters each.
Do not run parallel upgrades and prechecks at the same time.

Using the /v1/upgrades API to trigger parallel cluster upgrades across workload domains in a single API call does not upgrade the clusters in parallel

When using the VMware Cloud Foundation API to upgrade multiple workload domains in parallel, including multiple resource upgrade specifications (resourceUpgradeSpec) in a single domain upgrade API (/v1/upgrades) call does not work as expected.

Workaround: To get the best performance when upgrading multiple workload domains in parallel using the VMware Cloud Foundation API, do not include multiple resource upgrade specifications (resourceUpgradeSpec) in a single domain upgrade call. Instead, invoke the domain upgrade multiple times with a single resourceUpgradeSpec for each workload domain.

You can also use the SDDC Manager UI to trigger multiple parallel upgrades across workload domains.
