Can the DIVAR Network 2000 send SNMP traps via Operator Client when the HDDs are full?
This is not possible. According to the Release Letter for V3.1.1 and V.3.2.0 - "SNMP- No traps are launched for HDD status changes and recording stops".
The HDD_STATUS_CHANGE is triggered when the status of the hard disk changes. The HDD can have the status: OK, BAD, ERROR, MISSING.
So basically, it gets triggered when the hard disk stops working or when it gets physically removed.
If you want to get a notification when the HDDs of the DVR are full, you can Use System alarm to send email → get the alarm Disk Full and configure your Divar to send e-Mail on this event.
