bad magic supernumber - esx boot crash

esx comes up but shows that one or several volumes are in accessible
shows their eui / naa
fsck.ext3: Unable to resolve UUID
make a note of the fcuked UUID

could try this
df lists all volumes, as /dev/sdxx where xx is hex number
fsck.ext3 -f /dev/sdxx   run this command on each volume on the df list to do a scandisk

still show up fcuked ?
then hash them out in the fstab file if applicable
Confirm these same values in the /etc/fstab file.

# cat /etc/fstab

  1. Log into the server using the root password.
  2. Remount the root filesystem in read-write mode with the command:

    # mount / -o remount,rw
  3. Open the /etc/fstab file in a text editor.
  4. Comment out or remove the line referring to the previous ESX installation by inserting a hash symbol (#) at the beginning of the line.
  5. Save the file and exit the editor.
  6. Reboot the ESX host.
Prob still end up rebuild the esx host
