<div class="section"><h4 class="sectiontitle">Usage</h4><p>The host version is retrieved and saved whenever
|
|
a connection is made to the system; this API does not go to the host to get
|
|
it on each call. The system must have been connected previously, though not
|
|
necessarily at the time the API is called. Host information can only be retrieved
|
|
for systems configured in the currently active environment.</p>
