HP Systems Insight Manager - Manual (Page 172)

WMI Mapper
If you have created subscriptions on a Windows managed system and then elect to change the
WMI Mapper proxy or install a WMI Mapper on the managed system, you must first unsubscribe
for WBEM events, change the proxy, re-identify the systems, and then resubscribe for WBEM
events. If you do not unsubscribe for the WBEM events, Systems Insight Manager will no longer
receive indications from the managed system.
