Adding c-Class Enclosures systemname issue

Hi,

I am adding a handful of c-Class enclosures via the "Manage Hosts Files" method, but one enclosures always append the serial # after the system name defined in "Onboard Administrators" Enclosre Name. ie HPENC0001_YY3990ABCD.

I've tried readding this enclosure with "Automatically discover systems in an enclosure when Onboard Administrator is discovered" disabled under General Settings for All Discoveries after deletion.

Any ideas?

Edited: I should add this is HP SIM 7.3 with update 1.

Regards

J
