Hi,
Just as an FYI to all the folks with IBM hardware...
DPM can be setup with the IP and hard-coded MAC address being used by your IMM management connection. It will also require the username and password for your IMM setup. I've just tested entering and exiting Standby Mode, and it works very well.
I just had to make that known, since in so many online communities I've seen the very valid complaint that IMM is not mentioned as a valid Baseboard Management Controller (BMC) in any documentation. That being the case, a lot of folks believe that DPM and IMM are not compatible.
Later,
NYSteve
