Issue/Introduction

Symptoms:

After upgrading to vCenter Server 5.0 Update 1, you experience these symptoms:

• vCenter Server tries to upgrade the vpxa agent and all hosts are marked as disconnected.
• In vCenter Server, you see the Upgrade vCenter Agents on cluster hosts task in progress, but the task never completes.
• This issue may occur if the upgrade of vpxa agents was set to manual in a previous upgrade of vCenter Server.
• You may see this report on the Host's Summary tab:
  
  Disconnected from host Reason: Agent is out of date and needs a manual upgrade
  
  
• In the vpxd.log file, you see entries similar to:

Cause

This issue occurs if the autoUpgradeAgents option in vCenter Server advanced settings is set to false and vCenter Server incorrectly tries to upgrade the vpxa agent a second time on the ESX/ESXi hosts

Resolution

This issue is resolved in vCenter 5.0 Update 2 and vCenter 5.1 Update 1, available at VMware Downloads.

To work around this issue, change the autoUpgradeAgents option to true.

To change the autoUpgradeAgents option to true:

1. Click Administration > vCenter Server Setting > Advanced Settings.
2. Look for the AgentUpgrade.autoUpgradeAgents option and change this setting from false to true.
3. Restart the VMware VirtualCenter Server service.
4. Manually reconnect all ESX hosts.

The Upgrade vCenter Agents on cluster hosts task now completes.
