Upgrading to ESXi 5.x using Update Manager 5.x fails with the error: software or system configuration of host is incompatible

Products

• VMware vCenter Server
• VMware vSphere ESXi

Issue/Introduction

Symptoms:

• Upgrading an ESXi 4.x host to ESXi 5.x using Update Manager 5.x fails
  
• You see the error:
  
  software or system configuration of host is incompatible. check scan for details.
  
  
• Upgrading an ESXi 4.x host to ESXi 5.x with vCenter Update Manager 5.x fails with the error:
  
  Cannot run upgrade script on host
  
  
• In the /var/log/vua.log file on ESXi 5.x or /var/log/vmware for ESXi 4.1 and earlier, you see entries similar to:
  
  WARNING:root:Couldn't load esximage database: ('/bootbank/imgdb.tgz', "Failed to open tar database: [Errno 2] No such file or directory: '/bootbank/imgdb.tgz'."). Host may be incorrect version.
  
  
• You are upgrading these software modules:
  
  
  • oem-vmware-esx-drivers-net-vxge (10 GB Neterion Network Card)
  • oem-vmware-esx-drivers-scsi-3w-9xxx (3Ware SCSU Network Card)

Environment

VMware ESXi 4.1.x Embedded
VMware vSphere ESXi 5.0
VMware vCenter Update Manager 5.0.x
VMware vSphere ESXi 5.1
VMware vSphere ESXi 5.5
VMware vSphere Update Manager 5.1.x
VMware ESXi 4.1.x Installable
VMware vSphere Update Manager 5.5.x

Cause

The compliance status may be incompatible when you perform an upgrade scan of ESX 4.1 Update 1 hosts against an ESXi 5.x upgrade baseline. The remediation of ESX 4.1 Update 1 hosts against an ESXi 5.x upgrade baseline may fail. The scan and remediation problems are caused by third-party drivers in the ESX 4.1 Update 1 installation. After an upgrade scan of hosts, more information about third-party software is provided in the conflict details for the upgrade baseline.

Resolution

To work around this issue, try these options in the order specified:

• Workaround 1

1. Reboot the affected host. For more information, see ESXi/ESX 4.x and ESXi 5.x shutdown and reboot commands (1013193).
2. Rescan the host against the existing baseline via Update Manager.
3. Remediate the host via Update Manager.
   

• Workaround 2

Check if the issue is caused by one of these types of drivers and perform the appropriate workaround:

• Async drivers, such as oem-vmware-esx-drivers-scsi-3w-9xxx (3Ware SCSU Network Card).
  
  The vendor releases drivers asynchronously for ESXi 5.x, and the drivers are made available in the VMware patch depot.
  
  To work around this issue:
  
  1. Download the required drivers.
  2. Use Image Builder CLI to build a custom ESXi image which contains the required drivers.
  3. Remediate against the custom image.
     
     Note: Without the ESXi 5.x drivers, pertinent hardware devices may stop functioning.
     
     
• Deprecated drivers, such as oem-vmware-esx-drivers-net-vxge (10 GB Neterion Network Card).
  
  The driver is discontinued in ESXi 5.x because the pertinent hardware is discontinued.
  
  To work around this issue:
  
  1. In the Update Manager Remediate wizard on the ESXi 5.x Upgrade page, de-select any installed third-party software that is incompatible with the upgrade.
  2. Continue with the remediation.
     
     Note: Be aware of the functional implications of third-party software removal, because pertinent hardware devices might stop functioning.
     
• Workaround 3

Perform the upgrade using a scripted or interactive upgrade.

Additional Information

By using the Remediate wizard, you can ignore some upgrade scan warnings and force a remediation even if the upgrade warnings are not related to third-party software. On the ESXi 5.x Upgrade page of the Remediate wizard, you can remove installed third-party software that is incompatible with the upgrade and continue with the remediation to remove third-party software installed on the host and to ensure a successful remediation. Selecting the option also forces Update Manager to ignore three potential issues that are not related to third-party software.

These warnings are associated with the potential issues:

• The root password is encrypted with DES encryption, causing it to be authenticated up to only 8 characters.
  
• VMkernel and Service Console network interfaces are sharing the same subnet. This configuration is not supported after upgrade. Only one interface should connect to subnet. Unsupported devices <DEVICE_NAME></DEVICE_NAME>found on the host.

Before a remediation, perform an upgrade scan and review the messages in the Upgrade Details window of Update Manager. Take the necessary actions recommended by the messages to ensure that the remediation succeeds.
