How to remove a VMware Vcenter entry.

[Micke_Ch_1]

Hi!
I have repaired a HPSIM installation with a new installation. But it seems that some information is still, unfortunately some information is still in the database.
Under Options-> VMware vCenter settings the CMS/vCenter is in. Bute some information is missing, eg user name and port information. When I try to remove it says:
"System Name/Address" cannot be empty string or only spaces.
Is it some mx-commands that I can use to remove this entry??

Thanks in advance...
Best Regards
