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.
