Description Nick Strugnell 2003-11-06 16:15:59 UTC

Description of problem: 
When installing on a Compaq that uses the cciss driver, anaconda 
will install grub to the first external disk, rather than the 
internal disk - the result is that the machine will not boot. 
 
This is because anaconda thinks that sda (the first LUN on the SAN 
or external disk pack) contains the MBR. Anaconda should realise 
that on machines that use the cciss driver, the MBR is actually 
located on cciss/c0d0. 
 
Version-Release number of selected component (if applicable): 
 
all versions on all versions of RHL and RHEL 
 
How reproducible: 
 
always 
 
Steps to Reproduce: 
1. Install on a Compaq that uses the cciss driver (e.g. DL380) and 
that is connected to a SAN or some other form of external storage. 
2. Choose MBR for location of bootloader. 
3.  
   
Actual results: 
Machine will not boot 
 
Expected results: 
boot 
 
Additional info: 
Workaround - disconnect SAN during installation.

This is not generally true.  There is no way to reliably determine
boot order on x86 hardware.  This is why the advanced boot loader
options screen allows you to reorder the drives to match what your set
up is.
