[dm-devel] [PATCH] Reattach device handler for multipath devices

[Hannes Reinecke]

Hi James, Aladair,

when using multipath the daemon might have specified
a different device handler than used by default.
(Eg Clariion in ALUA mode).
For these cases we currently cannot setup a multipath map
automatically as scsi_dh_attach() will fail.
Instead we should be trying to reattach with the correct
device handler and only return an error if that fails.

Please apply.

Cheers,

Hannes
