HP Proliant DL380 Gen9 Got Wet during Hurricane Irma, Hard Drive still good, can I just plug to a new identical server
Solution 1:
The RAID configuration information is stored on the hard drives.
I would recommend plugging the hard drives back in to the same ports as they were plugged in to. Lastly, before proceeding to boot make sure your BIOS is configured to use and boot the RAID adapter and go in to the RAID configuration utility and make sure it recognizes your RAID 1 volume.
You shouldn't have any trouble.
However, whatever you do, do not try to initialize a RAID array or proceed to do anything that might try to rebuild the array if for some reason you are not seeing a healthy RAID volume right away.
