Sometimes when you attempt a DLPAR and you get the "no RMC Connection" error, the HMC may get out of sync with the LPARs. To sync the processor entitlements back up, use the following command by logging in to the HMC as padmin and running this command:

rsthwres -m managed_system_name -r proc
There are similar commands to re-sync the memory and IO adapters:
rsthwres -m managed_system_name -r mem
rsthwres -m managed_system_name -r io

Reset config:
/usr/sbin/rsct/install/bin/recfgct

lspartition -dlpar
