Error
dr: Failed to offline: cpu
Description
A CPU could not off-lined, preventing it from being unconfigured. The CPU
might have a thread(s) bound to it. An additional cmn_err message is
logged if there are threads bound to the CPU. DR must be able to off-line CPUs
and/or to power off CPUs before the board can be disconnected.
Recovery
Check the console and system log messages to determine if threads are bound to
the CPU. If they are, they can be manually unbound or rebound to CPUs on other
boards in the domain.
If threads are not bound to the CPU, use psrset(1M), pbind(1M), and
psrinfo(1M) to determine what changes are required to enable DR to off-line the CPU.
For example, you might have to add more CPUs to the domain from different boards. Or,
you may have to online other CPUs. Finally, you might have to add more CPU boards
to take over the CPU workload.
