Im having a similar problem.
Hp SIM 7.4 and StoreOnce 4700.
We are using SNMP v3.
After running discovery, we get a "Major" error, saying that the system cannot be identified properly for SIM to manage.
When i go into SIm, it has been discovered, and has management protocols:
SSH-2.0 and SNMP 3.0
I have downloaded the MIBS from HP, and tried reinstalling them:
SEMI-MIB and TRAP-DESTINATION-MIB
However when trying to reinstall TRAP-DESTINATION it tell me to remove the old MIBS, even though i have already removed the previously...
Does anyone have any suggestions?
