Hitachi HNAS: Status of Physical Nodes (PNodes)
Checks the status of Physical Nodes (PNodes) 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 "up" or "online". Returns WARN on
state "notUp". Returns CRIT on state "dormant" or "dead" and
UNKN on every other state.
If SNMP returns a name of the PNode, the item is build up combining the ID and this name. Otherwise it's just the ID.
Creates one check for every PNode in the HNAS system.
