Dynamic Reconfiguration User's Guide 2.5.1

5.2.2 DR detach failed with "Fail to offline the CPU.[processor_id=#]" or "Failed to off-line: dr@0:SBX::cpuY"

The DR detach operation tries to resolve the issues that cause CPU offline failures as much as possible but it may not be able to resolve all issues. When DR fails with the above message, please check these three points and offline active CPUs by psradm(1M) and retry the DR detach operation.

Checkpoints:

• Check if there still exists a process bound to one of the CPUs on the outgoing system board. If it does, unbind the process by "pbind -u" and check if it is really unbound by pbind.
• Check if any outgoing CPU doesn't belong to any processor set by psrset(1M). If there is an outgoing CPU that belongs to some processor set, remove the CPU from the processor set by psrset -r or remove the processor set by psrset -d.
• Check if there is at least one active CPU running on another system board.
