During several reboots of hosts in my lab, the vCLS virtual machine became inaccessible. However, a new one has been created, but old objects still exist in the vSAN. I see inaccessible objects in virtual objects. In this post, I want to show you how to remove such an inaccessible object in vSAN. Just make sure to identify the objects and confirm that they are not needed and are safe to delete. 1- Open an SSH session to the vCenter and enter the command “rvc localhost” in the command line. 2- Navigate to the vSAN cluster you want to remove the inaccessible objects using “cd” and utilize “ls ..read more
