The remediation process of an ESXi host against an upgrade baseline or a baseline group containing an upgrade baseline might fail.

Problem

An ESXi host might fail to upgrade.

Cause

When you upgrade an ESXi host with less than 10MB of free space in its /tmp directory, although Update Manager indicates that the remediation process completed successfully, the ESXi host is not upgraded.

Procedure

  1. If you see an Agent Deploy failure, make sure that the /tmp directory has at least 10MB of free space.
  2. Repeat the remediation process to upgrade the host.
