I have a remote W2K server with mirrored drives. In the event of the primary drive failure, how do I configure the boot.ini file so that it'll automatically boot from the secondary drive after a soft reboot?

Hi,

Its the rdisk value that changes. I believe that you'll currently have the value 1 and you need to set it to 2 to boot from the other disk.

multi(0)disk(0)rdisk(Z)partition(W)

You have two ways of doing this.

1. If the disk fails andthe machine is still running, then you can simply alter the boot.ini and reboot.

2. If the machine crashes or you shut it down after the disk fails, then you need to have created another boot disk with the boot.ini modified to allow you to boot from the second disk.

Having said all that, it is by far the best solution to have hardware based raid, then you dont have to worry about this as you're specifying the "controller" in effect, rather than individual disks. The hardware should take care of it...

Cheers,
Tim.
