change bad scsi controller on raid1

[Joseph]

Hello,
I have a Windows 2000 server standard edition. The physical disk has 2
volumes. The "system" volume 0 and "data" volume 1 are configured with a
software RAID 1.
I have a failed redundancy on the "system" volume but not on the "data"
volume. Both physical drives are connected to an external Adaptec SCSI
39160/3960D Ultra 160 SCSI adapter. This is the second time this has
happened in less than a year. I believe I have a bad SCSI controller card.
How do I replace the controller in the existing OS with a new controller?
Can I install the new drivers on the existing OS prior to installing the
hardware and then reboot hoping for plug n play? I have a boot.ini file
configured and will break the mirror to find out if it's a bad drive, and
hope to resync another RAID1. I just want to avoid this issue anytime in the
near future again. Thanks for you input.

Joe

You better back up everything before breaking the RAID

also, before even attempting to replace the controller, you should run the
mfg's diagnostic
on all the drives in question...the drive itself could be the problem
