@ -1816,6 +1816,14 @@ The list of support hints is:
* vendor (STRING): device vendor
* serial (STRING): disk serial number
* size (INT): size of the device in GiB
.. note::
A node's 'local_gb' property is often set to a value 1 GiB less than the
actual disk size to account for partitioning (this is how DevStack, TripleO
and Ironic Inspector work, to name a few). However, in this case ``size``
should be the actual size. For example, for a 128 GiB disk ``local_gb``
will be 127, but size hint will be 128.
* wwn (STRING): unique storage identifier
* wwn_with_extension (STRING): unique storage identifier with the vendor extension appended
* wwn_vendor_extension (STRING): unique vendor storage identifier
