(There is a check box at the top that will select all) Then at the bottom, click the delete button. All but the HP SIM box will be deleted. Then go to Options --&gt; Discovery task and run the task that will discover the IP segments that you want discovered. <BR /> Wed, 16 Dec 2009 01:14:23 GMT Eddie J.

Recently the rx machine is downgraded from rx8640 to rx8620. I have some discovery issue with the SIM after the hardware replacement. So i want to delete all the machines from the SIM db and rediscover the machines. Is it possible to delete the managed nodes from the SIM db and rediscover them freshly. Please Advise.<BR /><BR />Thanks,<BR />Jayaprakash S.
