Hitachi HNAS: Status of Virtual Nodes (VNodes or EVS)
Checks the status of Virtual Nodes (VNodes, also called EVS) in Hitachi
HNAS storage systems.
It was tested against Hitachi HNAS Modell 3090 but probably will work
for other HNAS devices too - give it a try.
Returns OK if the reported state is "onLine". Returns CRIT on state
"offLine" and UNKN on every other state.
The PNode it runs on and the admin status are displayed just for info.
If SNMP returns a name of the VNode, the item is build up combining the ID and this name. Otherwise it's just the ID.
Creates one check for every VNode in the HNAS system.
