Subject: Reattach device handler for multipath devices

|

References: bnc#435688

The multipath daemon might have specified a different device_handler
|
||
|
|
than the one a device is attached to by default.
|
||
|
|
So we should try to re-attach with the user-specified device_handler
|
||
|
|
and only return an error if that fails.
|
||
|
|
And we should _not_ detach existing hardware handlers. This will
|
||
|
|
set the path to failed during failover.
