    Take the RAID out of the equation. AT this point there is nothing you can do about it.  You have corruption.

    Treat this like it was a non-RAID disk drive.  Do exchange recovery by the book, or hire a pro to help you with exchange.

    We have few options if you do not have a backup of the DBs:

    Option 1. Repair the DB, here is the help link:

    Note: COPY ALL DB FILES to some other location just in case before following below procedures. (follow it without skipping any steps)

    Note: Now repair process could take some time depending on the size of the database, so you might want to think one more time before you do this as this could have a lot of downtime which your new client might not like. I have seen ESEUTIL doing wonders for me where I was able to recover Exchange DBs for my clients but downtime is something you cannot control.

    Option 2. Remove logs files and try to Mount the DB.

    Note: Do this if you are ready for some data loss.

    Please remove all logs files from the DB folder apart from the DB files and then try to mount it.

    Option 3. Create PST files from all users cache outlook (only possible when you have cached mode ON obviously) and then mount a blank DB which should allow users to send/receive and then import all PST files to their mailboxes OR give them access to the PSTs with fresh mailboxes. Please do not mount the blank database before you have exported all the PSTs.

    Please run the command eseutil /mh and checked the your exchange database is dirty shutdown or not.

    If it's in dirty shutdown then try to soft recovery using the eseutil /r switch.

    If soft recovery unsuccessful the perfromt the hard repair of database. To perfrom the soft recovery and hard repair please refer below link
