2 x PC's with RAID 1 Mirrors running XP Pro
Posted on 2004-04-02
I have a client (small business of 4 PC's running peer to peer) who wants 2 machines (Office Server + home PC) both with RAID 1 mirroring and removable caddies. Both PC's to have identical hardware and both on XP Pro. The idea is that every day (or so), he will take one of the drives out of the office server, take it home, replace 1 of the drives in the home PC and regenerate the other home drive. So that the home PC becomes a mirror of the office server. In this way, if disaster strikes, he can bring in the PC from home and continue working. Also, he wants to be able to work at home and then bring BACK 1 drive and regen the office server - so as to update it.
I have started installing running 2 Adaptec 1200A's (IDE RAID card) and 4 x 80Gb W.D. ATA100 drives.
There is no critical data yet, just a few hrs of updating and app installation etc.
Problem is, after 1 machine is set up, when taking the HDD over to the other. The RAID BIOS reports (correctly) that there is a broken RAID array (broken mirror hehe) and you can duplicate or continue booting. If you duplicate, the PC is out of action for a couple hours = unacceptable. If you continue booting, it boots and the Windows version of the Adaptec s/ware pops up and (correctly) reports there is a problem. However, doesn't let me regenerate in Windows (the appropriate areas are greyed out).
1) Is my problem to do with XP knowing what hardware it was installed to (and therefore is not transferable)?
2) Can I achieve what is wanted with the above h/w and s/w combo?
3) Why can't I regenerate in Windows (this way he can get on with his work)?
