Hi guys..

we a HP 580server and a HP p20o0 storage, both connected with SAS direct attached cable(not sure of the proper name for the connection), the server has their own disk in a raid(SSD). I would rather install RH in the local disk and then mount the volume(i.e /var or /XX) as a partition..

but is this wise to install RH in the a storage volumen (partition) and set the server to boot from this disk?

it is conected by a SAS card sc08.

I tried it with no success, it wont boot. like if this cant see the disk while booting..

in the BIOS I set the boot controller as the sas HBA but I get the red screen of the server of Illegal Operation..
is there something else I should set up in the server BIOS to boot from the storage?

other thing is, the storage has 2 controllers, so from 1 controller there is cable connected to the server, and from the other controller a 2nd cable go to the server too.

the thing is how can I configure the multipath is the OS is no installed locally in the server..
