I know that :) but at the moment we were changing backup device because our old one become broken, so..... i have only one chance to get the data back :(


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.
Tht situation is opposite. Controller "remember" the configuration, but on disks there is no RAID config (they are all just in READY state). And in this case controller do not "want" to use config from NVRAM. I do not understnd why.

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.
Thanks, i'll try to, but i'm not sure how this drives were configured.
First of all it was done not by me.
Then 2 drives vere changed because of disks falure and Hot spare disks were used, so which drive was in what RAID is unknown. So i hope there is some port or utility to view the data on each hard drive to determine what part of which RAID it was.

Anyway thanks for your help

Dear All,
sorry for sending my request to so many maillists and looks like it is OFF TOPIC, but i have defenetley big trouble and kindly asking you to help.

I have had server running FreeBSD-5.4p9 and it was samba file server for MS domain (about 600 people).

Today we were changing power supply so we shut all servers down at 17:00.

After changing of UPS we start everything up and my LSI controller starts to claim that disk and NVRAM configuration mismatch.

When i tried to enter configuration console i have found out that all disks in my array are in READY state, that means they are not a part of any drive.

After rebooting (via simple exitting the configuration console withiut changing anything), server stopped to claim that configuration mismutch, but shows 0 Logical drives configured (while before i have had 2 drives):
Raid1 for the OS (2*140GB drives)
Raid5 for the data (3*140GB drives)
And one 140GB drive as a hot spare disk
LSI FW version is G119 from Aug 27 2004

I'm sure that disks are still containing the information, but i do not know how to restore the LSI data on disks to boot properly or mount this drive somewhere on different system to get the data.

ICP controllers support nondistructive build to build array from disks that already contain ICP information. But i have found nothing about the same function in LSI. And i'm afraid that this will erase (now i do not trust LSI) my info.

I did contact LSI support but 3 people answerred that one is on the vacation, the other on the business trip and the third one is ill..... nice support. THere is nothing to say :)

In case there is no way to restore my configuration and continue to use this server as it was could you please tell me the way to restore data

from that drives?

Best regards,
Anton NIkiforov
