How do I disable san/fiber channel connectivity at boot when using the RH/Centos 6 installer

[Kovacs, Corey J.]

Not sure if it's still useful but there used to be a 'nostorage' option you could put on the boot line. Then you had to specify what you wanted to load in the preamble of the kickstart file. Not sure if it's still there tho. For example.

device scsi cciss

would work for rhel4/5 and HP gear.

On rhel6+, you'd put 

device hpsa

for the same machine since the driver changed.


Another option is to figure out what storage drivers get loaded for your hardware and explicitly unload them in the %pre section if the install, for example.

%pre
modprobe -r qla2xxx


There are other ways but these have worked for me. Also, make sure if you are doing kickstarts with FC connected that your SAN is set up properly and fibre switches zoned etc or you could end up with a bunch of empty luns across the san.

Hope this helps.

Where do you have such a long list? If you choose "Specialized Storage
Devices" then you have a screen with tabs. Only the last one (for
searching) contains all items. If you want to find your local disk, just
stay on the first tab -- "Basic Devices". There shouldn't be any of your
luns on this tab.
I don't understand what could be a problem here.
