|Could try to reset the card if it is an add on card. If not might need to get data off if it will boot again. If a mirror remove a disk and try. See docs on how to remove a drive just in case.|
Some mirrors can be run on other machines.
In any case I'd get the data off the next time you get it to access the drive. Either the adapter is bad or a or both drives.Could be power issues to or motherboard.
