i don't understand the output... the t1000 has one 6 oder 8 core cpu? so why 32 cpus?
4 threads per cpu? or what is it? just have a look at the manpage of "psradm" it should explain your problems! |

yeah, I've been looking at the man pages, following the instructions exactly, but the desired disabling of those 31 virtual CPUs still doesn't work.

from the man page:
A processor may not be taken off-line if there are LWPs that are bound to the processor. On some architectures, it might not be possible to take certain processors off-line if, for example, the system depends on some resource provided by the processor. On some processors or under certain conditions, it may not be possible to disable interrupts for an off-line processor. Thus, the actual effect of being off-line may vary from machine to machine. |

I found a solution : psrset would unbind the attached LWP processes and then you can use psradm -f

Select Main Forum "Sun Solaris" and then click "New Thread", otherwise just post it here ( if, for some reason you cannot do the above )
