Hot swappable CPU's on SPARC64?

Hot swappable CPU's on SPARC64?

I noticed when I made a new kernel for my x86 that there
was an option for hot swappable CPU's. But this didn't exist
on SPARC... ?

I just acquired an Sun Enterprise 3000, and I think I read something
about hot swappable CPU's (?) or at least hot swappable something...

Something about the machine could continue running even if hardware
failed...

I wanted to try out this on Linux (the manual only referred to Solaris
- surprise surprise :).

We don't support cpu hot swapping.

Hot swapping a board on an enterprise system is no cake walk,
in fact you have to jumpstart the board with JTAG scans and
things of that nature.  It's a lot of work, and as these systems
get older and older the incentive to do this kind of work
diminishes.

Sorry.
