The properties of the Logical Units’ user interfaces originating from a physical device are
available using the GET IPaddr/2027_file command, where the IPaddr is the IP address of the
physical device in dotted decimal notation in ASCII. Service devices shall return an XML
document, see [6], describing all device supported Logical Units as the concatenation of all
Logical Unit block descriptions. The schemas for the 2027 file and opcodes in Annex B are
informative.
