Explanation:
When a flash device failure occurs, before physically removing the device from a host, you must decommission the device from Virtual SAN. The decommission process performs a number of operations in order to discard disk group memberships, deletes partitions and remove stale data from all disks.
How to do it. Flash Device Decommission Procedure from the vSphere Web Client
Log on to the vSphere Web Client
Navigate to the Hosts and Clusters view and select the cluster object
Go to the manage tab and select Disk management under the Virtual SAN section
Select the disk group with the failed flash device
Select the failed flash device and click the delete button
