You can look up the UUID with the blkid command.

Title:
  Intel RAID device not included in FSTAB, has to be manually edited
  into file to be detected by OS and mounted.

Status in “util-linux” package in Ubuntu:
  Invalid

Bug description:
  I can't seem to mount my RAID 0 volume, which is Intel's BIOS-based
  AHCI RAID manager. Here's what happened: I freed up an extra harddrive
  (not a RAID volume) in my Dell, and decided to install Ubuntu 8.1 on
  it, with XP residing on the primary, RAID drive. Since I'd had
  problems before installing on a second hard drive which resulted in
  neither Windows nor Unbuntu booting, I decided to unplug both RAID
  member drives so that the Ubuntu installation couldn't try any monkey
  business with them. When all was done, both Windows and Ubuntu booted
  nicely by selecting the boot drive from the BIOS boot options. The
  problem was, the Ubuntu installation didn't see and wouldn't mount the
  RAID NTFS volume, so that I can share data between the operating
  systems. The RAID volume is apparently active, since FDISK -l shows:

     Device Boot      Start         End      Blocks   Id  System
  /dev/sda1               1           6       48163+  de  Dell Utility
  /dev/sda2   *           7       60395   485074642+   7  HPFS/NTFS
  /dev/sda3           60396       60787     3148740   db  CP/M / CTOS / ...

  
  which are all partitions on the RAIDed drive. Also, dmraid -r gives 

  /dev/sdb: isw, "isw_diiiejfeia", GROUP, ok, 488281248 sectors, data@ 0
  /dev/sda: isw, "isw_diiiejfeia", GROUP, ok, 488281248 sectors, data@ 0

  Where "isw" indicates Intel software RAID, and 488 gig is about the
  size of half-terabyte drive. Also, dmraid -ay says that the array is
  already active:

  RAID set "isw_diiiejfeia_ARRAY" already active
  RAID set "isw_diiiejfeia_ARRAY1" already active
  RAID set "isw_diiiejfeia_ARRAY2" already active
  RAID set "isw_diiiejfeia_ARRAY3" already active

  Where ARRAY1,2, and 3 are presumably the three partitions on the RAID
  drive.

  However, there is no mention of /dev/sda2 (the main, NTFS partition)
  in /etc/fstab.conf, which has only these entries

  # Entry for /dev/sdc1 :
  UUID=419a3127-33b3-41ee-b346-1852839e0ac2 / ext3 relatime,errors=remount-ro 0 1
  # Entry for /dev/sdc5 :
  UUID=752cc207-4020-484d-bf62-a37c1026362e none swap sw 0 0
  /dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0
  /dev/scd1 /media/cdrom1 udf,iso9660 user,noauto,exec,utf8 0 0

  So, I'm guessing that I need to add a reference to /dev/sda2 by
  editing fstab, to be able to mount this partition but how do I get a
  "UUID" for it, and what parameters should I give?
