Re: USB disks

I am not sure that it has to be rebooted, but I wanted to make sure that this
was a permanent fix and not one that I would have to fight everytime the
system was rebooted.  The USB disk in question is supposed to be
permanently on the network.

Interesting..do you mean Redhat has to be "rebooted" - this is a 2.4
kernel you're talking about right?

Geofrey,

	 I found the problem.

	RedHat has to be booted.  The USB disk cannot have any
electrical current to the disk.
Then connect the USB to the RedHat system.  Now plug the USB disk into
the electrical current to turn it on.

	You will see the disk listed using

lsusb

	Reboot your system and the USB disk is recognized as the old
/dev/sdb again.

	I don't know why this works, but I am glad I have it working
again.

	Thanks for all your  help.

Try unplugging it, then type:

# tail -f /var/log/messages

Then plug it back in - you should see messages written to this file.

Nope.  I just see the system disk.

The device might have changed names - from /dev/sdb to /dev/sda/c/ d/e

etc

Can you see the device with:

# fdisk -l

I have a laCie auxiliary disk which has been working on a 2.4.21-53
RedHat system.  The disk was accidently turned off  during the
afternoon.  Now  I cannot get the  device recognized by  the system
again.  The  system can't  open /dev/sdb.

I was able to mount the disk on a newer RedHat system, but I need to

get it working on the previous  system.

What  should I do next?
