This report provides information about all detected shared datastores that are not mapped to any existing backup proxy. If you are going to use the Direct SAN Access mode, datastore LUNs must be mapped to a proxy server.
The Unmapped Datastores and Mapped Datastores sections display detailed datastore information, such as capacity the amount of free and used space, and the number of stored VMs.
The Direct SAN Access mode is recommended if the ESX(i) host uses shared storage. In the Direct SAN mode, proxy servers will not be able to read data from LUNs if they are not mapped. This report allows you to detect datastore LUNs that are not mapped to any proxy server in your backup infrastructure.
Scope: defines a virtual infrastructure level and its sub-components to analyze in the report.
