Create psrset

Here is how you can create a processor set with two cores (32 threads)

• psrset -c 0-31

if you get :

• An  "Operation not supported" error indicates that pool facility is active.

Disable the pool facility as under:

• svcs *pool*
• STATE          STIME    FMRI
• disabled       Feb_17   svc:/system/pools/dynamic:default
• online         Feb_17   svc:/system/pools:default
• you have mail
• # svcadm disable svc:/system/pools:default
• # svcs *pool*
• STATE          STIME    FMRI
• disabled       Feb_17   svc:/system/pools/dynamic:default
• disabled       11:44:04 svc:/system/pools:default

Create psrset with first 32 processors and verify that the processor set was successfully created

psrset 0-31

 psrset -i

user processor set 1: processors 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

The output indicates that process set named 1 has processors from id 0 to 31.
