Help needed to add/remove devices without rebooting.


Hi everyone,

I am new to Linux Redhat.

I need help to add/remove devices without rebooting my system in Redhat 9.
I know that in Solaris, you can use the command devfsadm -v, but what command
do I use to obtain this effect as in Solaris.

Any help given is greatly appreciated.

Good Day
sze han

There are many kinds of devices. For USB, IEEE1394, and to a lesser extent Serial, and Parallel ports, hot-plugging and unplugging) is usually possible. Just make sure, if a hot-plugged device is mounted on your filesystem, to unmount it before unplugging the device.

For PCI hotplug, I have no knowledge, except that it is supported for many cards in the kernel. But PCI hotplug only works for a few mainboards and PCI cards, that are designed to allow that. I'm sure you'll find a full list of those in the kernel documentation.

Yves.

"kudzu" command on RedHat system automatically checks and configure devices. Use it at root; it will generate a /etc/syscoonfig/hwconf ascii file in which it reports hardware specifications.
