Failed Raid card... can I save the data?

on
Raid card with a RAID10 set.

The card failed and I'm buying a replacement.  Will the replacement see the existing set on the 4 raid10 drives?

Or is the data lost?

Thanks.

I doubt you could even find a RAID controller that is so stupid it can't automatically "learn" the existing configuration from the metadata.   So answer is 99.99% yes, providing all the hardware is good.

Best practice is to insure that whatever replacement card you have is running same firmware version as the one you replaced.  All bets are off if the replacement card is running an old version of firmware.

Agree with dlethe.  You should be able to put in the new card and it see the config info that is stored on the drive.

If it's an identical make/model replacement then I would agree too but it's not at all clear in the question that the replacement will be identical. Knowing make/model of current card would help.
