After assigning volumes to the host, you perform a rescan so that the host detects and configures the volumes for multipathing.

By default, an ESXi host automatically performs a rescan every five minutes. A volume might appear between the time you create it and assign it to a host, before you perform a manual rescan. Regardless, you can perform a manual rescan to ensure all volumes are configured properly.

  1. Create one or more volumes and assign them to the ESXi host.

  2. If using a vCenter Server, add the host to the server’s inventory.

  3. Use the vSphere Client or the vSphere Web Client to connect directly to the vCenter Server or to the ESXi host.

  4. For instructions on how to perform a rescan of the storage on an ESXi host, search for the VMware Knowledge Base article on this topic.
