    • ​Inline with other HA features, such as vSphere HA or MSCS, Edge HA is not designed to deliver zero downtime as the failover between appliances may require some services to be restarted.

However, the time required to bring all services back up is not null. Examples of known service restart impacts include a non-zero downtime with dynamic routing when an Edge is operating as a router.

How to track the top field issues:

Web Client issues in vSphere 6

Today we’d like to talk about some common issues that have been seen when customers were upgrading to the latest version of our vSphere Web Client.

Perhaps you, during an upgrade, missed some products that were no longer supported (ie: removing plugins that are no longer supported), and now are proving to be reluctant to be removed. Most of these are not production stopping, though they are problematic when it is not expected.

KBs 2111224 and 211292 For customers who have upgraded and may have not seen the documentation on what other products are no longer supported in vSphere 6.0.

KB 1025360 Helps with removing plugins that are no longer compatible with vCenter 6.0.

KB 2119011 To help introduce customers to the feature changes in the vSphere Client and vSphere Web Client in 6.0 and any corresponding errors.

KB 2121185 After upgrading to vSphere 6.0 you may run into items no longer appearing in your inventory. This KB assists in troubleshooting to the services to find the cause.

KB 2121717 Troubleshoots login issues that customers may see in the vSphere environment using the Use Windows Session Credentials check box.


How to confirm ESX and ESXi host hardware compatibility

We’ve just put the finishing touches on a new video which discusses how to confirm ESX and ESXi host hardware compatibility using the VMware Hardware Compatibility Guides, which are available here.

You can use the VMware Hardware Compatibility Guides to confirm whether or not your particular server, system, HBA, network card, or other peripheral devices are certified and compatible for use with specific vSphere ESX and ESXi versions.

Additional information is available at Confirming ESX/ESXi host hardware (System, Storage, and I/O) compatibility (1003916).
