Re: Offlining a CPU
I would try to avoid changing the mask because it needs a reboot to undo. If you can get away with it, just use 'offline 3' or 'psradm -f 3'. Of course if that might not make the legal requirements...
I would also opt for mask '07'. btw... are the CPU tightly packed from the right front?
I don't understant how disabling a (non-primary) cpu would prevent access to the hard drives ?! What does show dev/ show config tell you at the P00>>> prompt ?
You did not accidently reboot from a different boot disk/file by accident? (show boot_def_dev or show boot*)
Also... which version/patchlevel of Tru64 ?
fwiw,
Hein.

Re: Offlining a CPU
I know that setting the CPU mask shouldn't affect seeing disks but when I leave the mask at ffff (where it was by default) I can boot to my disks and when I change it to fff7 I can see the drives with the sho dev but when I try to boot to any of them I get a message saying the drives are no longer valid. Maybe this is a seperate issue though.
I don't have a valid O/S on it right now (it corrupted during an LSM mirror function when CPU3 KMF'd. I can boot the image but the root domain is corrupted.) I do have firmware 6.3 on though.
Thanks for the help. -Steve

Re: Offlining a CPU
CPU # ( 1=enabled, 0=disabled)
1 2 3 4 CPU_ENABLED
1 0 0 0 = 1
1 1 0 0 = 3
1 1 1 0 = 7
1 1 1 1 = f or ff or ffff it doesn't matter
So to disable CPU 3 and enable CPU 0 , 1 and 2, you have to set the cpu_enabled to 7
