hi

I'm contacting you with an LDOM issue.

I currently have LDOM installed on Solaris10 on my T5120, and I'm having trouble with the  
I want to delete it.

I am using 8 gigs of memory and when I delete the LDOM, I am not getting 1 gig of memory back.

I would appreciate it if you could tell me how to do this.
