Thanks Todd,

just let me finally point out why I think this is that important (and why I digged into this deeper at all):
As the DSS represents some critical infrastructure element providing possibly many services to other servers (iSCSI,NFS), I want to make sure that
a) it shuts down last - i.e. after all servers depending on it
b) it shuts down correctly (and know when this might happen)
c) reliable comm with UPS - i.e. avoid using master-slave chains by getting with SNMP on the UPS
