psrinfo -p needs root login ?


I tried running psrinfo command on couple of machines but found that if i login as root then it works.
But when i login other than root account, I get this error,

$ /usr/sbin/psrinfo -pv | fgrep UltraSPARC
/usr/sbin/psrinfo: illegal option -- p
        psrinfo [-v] [processor_id ...]
        psrinfo -s processor_id

Can anybody explain, if i need root login to run psrinfo with '-p' option?
and i would also like to know if from which version of sunos psrinfo with '-p' option is supported ?

Thanks in advance,

psrinfo -p option will give how many processes are working
so this can be seen as u login as root
if u want to see to as user just give root permissions to user

sun solaris 10 os 8/07

Thanks for quick responce.

I wanted to find the information about physical processors only.
i.e. using "prsinfo -vp" command.

So you mean, i can be only run, if login is root ?

try prtdiag

What version of OS are you using? On Solaris 8,9,10 I could use psrinfo -pv as regular user. Other option is to try prtdiag command

I tried on 5.9 and 5.10, on both i see that only root user could execute prsinfo -pv,

otherwise i could run psrinfo -v with user other than root.

Does any other command gives information on physical processors, without login as root user?

Why can 't you just sudo power to that user for that command?

there is no "sudo" on a default solaris installation!
