Hi All,
Is there a quick way to upgrade to a different brand scsi controller?
Normally, we use backupedge to create a master backup and then reload
sco openserver from scratch with new scsi controller and after this
restore just the data portion etc.
Is it possible to re-link with a new btld and swap scsi controllers?
If anyone has done this , please let me know.
Thanks,
Shaukat

If that still works, put the new HW in and use the btld.

Auto lets the kernel try all the adapter drivers that you have linked
into it. If the kernel still only has the one old driver, you'll
accomplish nothing.

You also need to link in the other driver(s) you might want to use.

There is also the question of whether the new controller stores
data on the drive the same as the old one. In the case of RAID
controllers, this is rarely the case.

I have used Edge in the past and made a new kernel, then boot floppies,
then put the kernel back, then used the Edge Floppies to boot and
load.

But with what disks cost these days I'd sure rather replace the root
disk and keep the old root disk on the shelf until it is done.

I would agree with Neal. Just replace the drive along with the disk
controller. If worst comes to worst, you would still have a working Unix
drive system. Re-installing the old controller and restoring on the same
drive involves more time than replacing the drive system complete.
