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


An ESXi host might fail to upgrade.


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.


  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.
