lnetctl does not change NI health value from YAML configuration file

The purpose of it is to test that when the health value is set to something other than the maximum, then it gets put on the recovery queue. That's why you see the value not exactly what you set it. When it gets put on the recovery queue the interface gets pinged and with every successful ping the health value is increased. If you wait for a bit, the health value should go back up to the maximum value.</p> <p>I didn't add a way to change that from YAML. I know the test case says that, but now that I think about it, since this is a debugging command, I don't think setting it from YAML is a necessity.</p> <p>I'm now thinking that it might be a good idea to move this under the debug subcommand instead of keeping it in net. So might as well keep this ticket open for that purpose.</p> Development Rank 1|i004bz: Rank (Obsolete) 9223372036854775807 Severity
