Do you have provisioning entitlements on RHN.

Subject: Copying an rhel as 3 installation from a PowerEdge 2650 to a 2950

Hola,

  I'm tasked with adding a fourth system to an Oracle cluster, and a requirement is that it's at the same patch level.  I have been unable to find a redhat utility to take care of this, so rather spend time in RPM hell I decided to do file systems dumps of one of the cluster nodes and load it up on the other box. I copied an install from a PowerEdge 2650 to a 2950.

  These systems use different RAID controllers for the boot disk.  Because of this I have to load a new driver/module (megaraid_sas).  But, it is not working.  When I try to boot I get: 

VFS: Cannot open root device "LABEL=/" or 00:00
Please append a correct "root=" boot option
Kernel panic: VFS: Uname to mount root fs on 00:00

  I'm assuming that the megaraid_sas module is not being loaded.  If I do a fresh install from CD I can get the driver installed.  How does Redhat load kernel modules?  Because the system panics I can't scroll back to to verify what hardware is recognised. 

  Also, if anyone knows of a way to make one system match another system's patch levels that would be awesome.  I am able to register the systems on RHN.

Thanks for your time.
