Kernel panic when booting off SATA clone in Red Hat Enterprise Linux 4

Issue

• RHEL4 installed from CD onto PATA (IDE) drive. This PATA drive was then cloned onto an SATA SSD using the 'dd' command ( dd if=/dev/hda of=/dev/sda bs=4096 ). Changed references from 'hda' to 'sda' in grub.conf and device.map on the SATA drive. Verified there are no references to hard drive as 'hda' in fstab.

• Disconnected PATA drive, connected only the SATA drive to the system. Attempted to boot from SATA drive, with the following result:

  "Uncompressing...booting kernel 
  ... 
  No volume groups found 
  Unable to find volume group VolGroup00 
  ERROR: /bin/lvm exited abnormally (pid 429) 
  ... 
  Kernel panic: not syncing: Attempted to kill init." 
  

• RHEL was not directly installed on the SATA drive because the installation process did not find the drive

• It did install on a PATA drive, so we tried cloning.
