To verify the RAID set up, you may need to run the RAID configuration tool
in Compaq's SmartStart CD (boot from it). Therein you can view the mapping
between the logical/virtual RAID drive and the real physical drives.

# Subject: [ale] Compaq raid disk. How do I format?
# 
# 
# I've have an old compaq that a Windows tech added some disks 
# to but had 
# no idea what to do to make it work on Linux.  From the dmesg 
# listing I 
# found:
# 
# Compaq SMART2 Driver (v 2.4.5)
# Found 1 controller(s)
# cpqarray: Finding drives on ida0 (SMART-2/P)
# cpqarray ida/c0d0: blksz=512 nr_blks=8380320
# cpqarray ida/c0d1: blksz=512 nr_blks=16768800
# cpqarray ida/c0d2: blksz=512 nr_blks=17764320
# 
# It looks like he added ida/c0d2 since I have the other two drives 
# mentioned in the fstab file.  When I tried to look at one of the 
# existing drives with fdisk I found:
# Disk /dev/ida/c0d1: 1 heads, 16768800 sectors, 1 cylinders
# Units = cylinders of 16768800 * 512 bytes
# 
#          Device Boot    Start       End    Blocks   Id  System
# /dev/ida/c0d1p1   *         1         1   2044064   82  Linux swap
# Partition 1 has different physical/logical beginnings (non-Linux?):
#      phys=(0, 1, 1) logical=(0, 0, 33)
# Partition 1 has different physical/logical endings:
#      phys=(500, 254, 32) logical=(0, 0, 4088160)
# Partition 1 does not end on cylinder boundary:

# 
# Which makes me a bit leary of using fdisk on these drives.  
# Most of that 
# output doesn't make sense to me.  Can anyone point me in the right 
# direction so I can learn how to format this new drive?  This 
# is a RH 7.2 
# system.  If I understand correctly this is a RAID system.  The new 
# drive  is really 2 9 Gb drives configured as a mirror, so I 
# was told.  
# Is there some other utility I need to use to make sense of the 
# partitioning of the existing drives?
# 
# Thanks,
# Jim.
