Issue/Introduction
Were are running a stretched cluster across two separate data centers. Just noticed the following in skyline health (The stretched cluster does not contain a valid witness host). Not sure how long it has been this way or if it is a real problem. We do have a witness configured for this cluster.
Environment
vSAN (all versions)
Cause
When host upgrades are taking place vSAN Skyline health will trigger the alarm and other alarms in the health test while upgrading
Resolution
Continue to monitor alarms while upgrading, understand what they mean and ensure that alarm states clear before patching the next host.
Additional Information
vSAN Skyline Alarms give information to the health of the cluster. Understanding and monitoring these alarms ensure the cluster health and stability not only during upgrading but in day to day operations.
