RHEV-H local Boot Installation
Hi,
Whenever I install RHEV Hypervisor on a local disk (not a SAN LUN), it picks the device name as "/dev/mapper/wwid" and installation succeeds on this dev-mapper device.
How do I install on a non dev-mapper device. I do not want multipath capabilities for a local disk since it has just 1 path.
How do I install now on a "/dev/sda" device ?
When I select the "other device" option in the installation screen, and specify "/dev/sda", even then the installation proceeds on "/dev/mapper/wwid".
Any solution ?

by default we multipath everything, for the ease of addressing devices. Can you state a reason you would want to not use multipath really? How, on a host managed from RHEV-M GUI does it matter?
Thanks Dan. I agree to you. But still, my arguement would be, why adding a "extra layer of complication of device-mapper", when we really dont need that. This is not going to make the root any better in performance.In fault scenarios of the storage nodes, it will be an added task to scan etc.. even the local disk.
Hence ,I would prefer to go good old way.
You need to understand there is no complication here. RHEV-Hypervisor is an appliance and not an OS you need to manage internally. Usually there shouldn't be much of a reason to ever touch it except through the RHEV-M admin GUI or the API. This means anything inside the distribution is transparent to you, and has no relevance
