Hi,

Just to make sure, are you running "ioscan" as root ? If you cant run as root, try # ioscan -kfn.

Also, reading these threads should help.

You can use "ioscan -k" which will show you what is present in the kernel. That's what I usually run anyway because it's faster. The only time I don't use -k is if I've got newly attached hardware I'm looking for.

Actually ioscan with certain options is NOT limited to just superuser.

try

ioscan -fun

Hi,

You asked "Logged in ran ioscan with no options i get the error, but with options i am able to perform an ioscan. just to be sure there is nothing i can do as an admin to be able to perform ioscan without loggin in as root? "

Yes, a normal user cant do anything with ioscan..

Hi,
That is because ioscan without options updates /dev/config and /etc/ioconfig, which only root has write permission, there is a box where because of mad developpers trying to hack root passwd I only connect myself and had to compile a sudo so I have no passwd without timeout and works only when I call an alias of ksh...
So on this box I put myself in the /etc/group file in the groups bin, root, adm, sys, mail and modified the permission on the groups to /dev/config /dev/kmem /etc/ioconfig, and most files in /etc so in case Im stressed I will not sudo and can still do some tasks...
Dont forget there is also the possibility to grant yourself to all (most) tasks restricted sam (sam -r)

All the best
Victor

As a normal user you can not run just plain ioscan. And as an admin there is nothing you can do about that.

Victor has something there. You could use sudo or super to grant normal users access to ioscan (by it's self or with options)
