Moving OS to a SCSI from IDE?

AekaGSR · 09-02-2003, 11:08 PM

How much of a hassle is this? I was going to ghost the IDE hard drive to a SCSI hard drive and run Linux off of the SCSI drive thereafter. What else needs to be done for this to work correctly?

Redhat 9, Thanks.

"What else needs to be done for this to work correctly?"

You need to change /etc/fstab and your bootloader. If you aren't using a bootloader then you need to change your BIOS boot sequence.

Red Hat probably has both IDE support and SCSI support compiled into their kernel. If you have compiled your own kernel then check to make sure that SCSI support is compiled into the kernel and that it is not a loadable module.

thats it? I thought it would be harder for some reason. Ok thanks.

"thats it?"

Yes. I have three IDE disks and have moved Linux around several times. I never have used SCSI. The only problem I can see with SCSI is if you have SCSI support as a loadable module and then try to boot to a SCSI drive.

Welp, only one way to find out

You might want to make it the first scsi drive (/dev/sda#) in your scsi chain.

The /dev/sda# was a reminder of the nomenclature. Of course, I've been known to make "brain-dead" mistakes, when I hurry or do things at 2 am.

Default controller sets SCSI ID 0 as the boot device.

If your BIOS does not have a SCSI boot option device you will need to disable the IDE controllers.
