1 CPU missing

[Dani_Galera]

hi @ll,

i have one serber with 4 CPU

if you check 'top' you have:

System: sn42049 Fri Apr 14 01:31:07 2006
Load averages: 0.67, 0.67, 0.67
160 processes: 137 sleeping, 22 running, 1 zombie

seems to be working with only 3 CPU

but if you check ioscan or mstm all CPU are ok:

does anybody any idea about this problem?

Where was the last place you remember having it?

The first thing that I would do (assuming I am not looking at a VPAR) is look for any top cumulative patches. It really helps when you identify your OS version and hardware.

Shalom,

top is not a good judge of how many cpu's are there, especially with the advent of dual core cpus.

fire up cstm or mstm or xstm and see how many cpus are present and test if they are functioning.

Dani ,

Also check from GSP, with ss command, for the cpu status.

Cheers,
Raj.
