As with any IT infrastructure, you will occasionally encounter problems in your VSAN implementation. VSAN is designed to always enforce and maintain the integrity and consistency of production data, but this does not mean that outages or even data loss are impossible. In combination with the alarms discussed in Chapter 4, Monitoring VSAN, this chapter can be used to investigate common problems with VSAN configurations, settings, or components to enable you to return the cluster to service.

The procedures outlined in this chapter are general and seek to address common problems with VSAN configurations. In the event that the steps outlined in this chapter are inadequate or you encounter a different problem, you may need to contact VMware Support or your third-party support provider. To prepare you for the best support experience, please see Chapter 8, Support Success.
