We have a QNAP TS-463U NAS with 4 logical volumes. One is the system DataVol. The other 3 are volumes used by a Microsoft failover cluster via iSCSI (quorum plus 2 CSV's). When I attempt to add the QNAP Logical Disk Sensor, it only displays the system DataVol as a selectable volume in the setup -- the other 3 volumes are not displayed.
Any ideas what might cause this? We are using SNMP v2c.
