https://community.hpe.com/t5/server-management-systems/snmp-data-renewal/m-p/4522929#M39235 On the system properties page in SIM there is a checkbox called "Prevent the Discovery, Identification and Data Collection processes from changing these system properties".<BR /><BR />Is this perhaps active on your systems?

But it looks like changes in agent properties (sysContact or sysLocation) are never reflected in HP SIM database. Subsequent attempts to "identify" or "discover" the existing system do not change anything inside SIM DB. Only delete and discover "helps". But this is unaccepatable because settings tends to change ...<BR />Can anyone help with this problem ?<BR /><BR />PS: we use these parameters to filter systems from a lot of locations Wed, 28 Oct 2009 12:38:55 GMT https://community.hpe.com/t5/server-management-systems/snmp-data-renewal/m-p/4522928#M39234 dimka_2 2009-10-28T12:38:55Z https://community.hpe.com/t5/server-management-systems/snmp-data-renewal/m-p/4522929#M39235 On the system properties page in SIM there is a checkbox called "Prevent the Discovery, Identification and Data Collection processes from changing these system properties".<BR /><BR />Is this perhaps active on your systems?
