Description of problem:
When installing RedHat 7.2 on a machine with only SCSI hard drives and a
usb-storage unit is plugged in the installer allocates sda to the
usb-storage unit.  The simple work around is to reinstall the OS without
the usb-storage unit plugged in.

Version-Release number of selected component (if applicable):

How reproducible:
Didn't try

Steps to Reproduce:
1.  Setup a SCSI only system with a usb-storage device
2.  Boot off a SCSI CD-ROM
3.  Step through the normal install procedure
4.  The hard drive that would normally be sda becomes sdb due to the
usb-storage device.

Actual Results:  The system would not boot because /etc/fstab had bad
values.  Also GRUB did not have the right configuration.

Expected Results:  sda should be consistant between the installer and the
actual boot.

FYI, there is a boot disk which works around this problem at

This disk changes things so that we remove the usb-storage driver before loading
any other SCSI drivers and also adds a "nousbstorage" flag which can be passed
on the syslinux prompt to disable loading the usb-storage module altogether.

Does the updates disk fix the problem?
Comment 3 Ian Prowell 2001-11-03 14:41:09 EST
I already finished installing RedHat 7.2 on the only workstation I have that
only has SCSI.  I assume the provided boot disk solves the problem.  Just wanted
to make sure that this got into the install documentation or was solved by an

Ok.  This problem should not appear in future releases.  Thanks for your report.
