I hope you have a backup :-) RAID does not guarantee bulletproof protection against data loss. When you saw this mismatch, you should have went into RAID's BIOS and restored configuration from disk. Most likely the NVRAM version got corrupted. The only thing left to do is go back to controller's setup CTRL+M at bootup, select new configuration and resetup both logical drives and standby EXACTLY and I mean EXACTLY how it was setup the first time. At this point, DO NOT initialize the logical drives, just reboot the server. If you reconfigured like it was done the first time, your server should boot and see logical drives with all data intact, unless something went really wrong with the drives and the data is corrupted. Good luck, I will keep my fingers crossed for you. I had similar experience with Mylex card on live server, it wasn't fun at all.
