cio_ignore=all,!009
appears to be the default, at least on RH 6.2... Certainly not added by
us...

Hi all,
I've been trying to think of any reason to ever have cio_ignore in a VM
guest. I can see real use for it in an LPAR where you may have
thousands of devices that have nothing to do with the Linux instance.
But in a virtual machine I only give it the devices I want it to have in
the first place.
Teaching it to new comers, they can easily understand chccwdev -e as the
logical equivalent of varying something online to VM or z/OS. With
having to issue a cio_ignore -r then a chccwdev -e I keep getting asked
why they have to vary it online twice. And I don't have any good answer...
Thoughts? Insights?
With cio_ignore you can modify the device blacklist. The reason you have
to remove a device from the blacklist before you can use it is that you
have added the device to the blacklist in the first place.
So either you did a "cio_ignore --add" earlier or you have set the
cio_ignore kernel parameter (most likely the latter).
If you want linux to use all available device simply remove the cio_ignore
kernel parameter.

Sebastian
