Idrac critical alert for virtual disk


Since the start of the week, we’ve been getting the following alert for all of our server idracsevery time discovery is running.

Rule: State Sensor Critical


#1: sysObjectID => .; location_id => 33; sensor_id => 507; sensor_oid => .; sensor_descr => Virtual Disk 0; state_descr => failed;

According to the VD state graph and the event log, the state for that sensor hasn’t changed to justify getting this alert. Additionnally, I’ve disable alerting for the virtual disk sensor on all idracs and we are still receiving alerts.

Probably the discovery is setting the value incorrectly. Can you pastebin discovery.php -d -h HOSTNAME?

Here you go:

Strangely, the last discover job only triggered the alert on one of the idracs which happens to not be the one from the previous paste, so here’s one for that device too:

Hi All,

we’re encountering the same problem, here our Libre version:

Currently we’re bound to disable those alerts, is there any fix in progress?

Here a pastebin of our discovery.php -d -h HOSTNAME :
