Not to easy to do. You need to write a collector plugin to get the

Hi Erik,
I'm passing the SNMP request to external script to handle the data.
Is there any way to add the hard disks automatically?
I tried the Zenoss-Plugins, but it shows no plugin is suported?
I'm running RHEL 4 ES x86 and Zenoss-Plugins 1.0.2 RPM for python 2.3
