I'm new to the forums here but hopefully I can assist on future issues...
Chas, I own a Proliant myself and just purchased a second processor. I'm looking up white papers now for dual cpu settings..
I can answer the controller cd issue. You'll need smartstart 5.5. Link can be found here.
I hope I'm not going against forum policy. As I stated, I'm new here.
Hope this points you in the right direction. I'll workout the dual processor errors and repost.
I'm reading that the smartstart cd is required for the cpu errors. I'm trying the system config utility now. (smartstart cd)
I booted into the smartstart and ran system config. Both cpu's are up and running.
Hope this helps.
