Imagine I have a number of block devices, that I know are the same device but who have different identificators (it may be a device cut and clued with
dmsetup, exported multiple times through iSCSI, etc.). I can guarantee the same volume of them, yet they may have different types (physical device and FC target, for instance). I want to multipath them via
man reads, that I can force different policies, but can I force multipath maps themselves? Whatever is the method for detecting path failure, whatever is the path priority policy, it does not depend on device type or their serial/IQN, so I see no conceptual problem in here. However, I do not find anything like that in documentation.
