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.
Your best bet is to do a google search.
Doing that :)
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.
Likely the controller has some battery backed up RAM that got
zapped? My guess is your disks are fine (which is why they
are in ready state) but the NVRAM data evaporated -- likely
the battery is dead? Or may be something died or got
damaged.
Controllers hav no RAM backup battery. THe servers were shutdown just
properly and have had to save all the data whereever they should.
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.
At least make a complete image backup of each disk
individually.
What you consider a "safe way" to backup all disks?
To connect them to the ADAPTEC controller and dd to the image files? in
this case how to determine exact number of blocks?
(Sorry for my stupid questions, i just do not want to loose this data,
so trying to become 100% sure what i'll do next minute)
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 :)
Keep bugging them (persistently but nicely). Get them on
your side. Don't get them mad or give up. Eventually they
will get rid of you by passing you on to a real techie. Who
will tell you what you *should* have done (after losing all
your data while "helping" you -- see, he wants to understand
the problem even more badly than you do but he doesn't care
for your data -- after all everybody knows customers run beta
sites, right?).
Oh! Belive me i'll :)
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?
You can try putting in fresh blank drives, duplicating the
exact configuration and then reconnecting your old drives.
I have no drives of the same size and type :( so, i'll have to copy
images somewhere on the different server and test this drives

And TELL US WHAT WORKED (just on freebsd-hardware)! That is
your punishment for duplicate posting.
