You can co-manage a managed system by using both PowerVM®
NovaLink and the Hardware Management Console (HMC). However,
you cannot use partition profiles and system plans on a co-managed system, even if the HMC is set to
the master mode. To use partition profiles and system plans on a managed system, you must remove
PowerVM
NovaLink from the managed system.
Before you reset the PowerVM
NovaLink-managed system to
an HMC-managed system, cable the server to an HMC if you have not already done so. For information
about how to cable the server to an HMC, see Cabling the server to the HMC.
To reset a PowerVM
NovaLink-managed system to an
HMC-managed system:
- Set the HMC to master mode by entering the following command at the HMC command line, where
managed_system is the name of the managed system.
chcomgmt -o setmaster -t norm -m managed_system
- Power off the PowerVM
NovaLink partition by entering
the following command at the HMC command line. In this command,
managed_system is the name of the managed system and
partition_id is the partition ID of the PowerVM
NovaLink partition.
chsysstate -m managed_system -r lpar -o shutdown --id partition_id --immed
- Remove the PowerVM
NovaLink partition by entering the
following command at the HMC command line. In this command,
managed_system is the name of the managed system and
partition_id is the partition ID of the PowerVM
NovaLink partition.
rmsyscfg -r lpar -m managed_system --id partition_id
- Release master authority for the managed system by entering the following command at the HMC
command line, where managed_system is the name of the managed
system.
chcomgmt -o relmaster -m managed_system
