Yes, I've done it!
multipathd uses /sbin/scsi_id to determine which block devices are really the
same as eachother. (Actually, the callout is configured in /etc/multipath.conf,
but its usually /sbin/scsi_id).
If /sbin/scsi_id returns the same ID for two block devices then you should be
able to failover between them.
The path failovers are handled by the kernel part of the device-mapper-multipath
package, and path recovery is handled by multipathd.

Hello,
I am wondering if it is possible to failover an iSCSI path from one EUI
/ IQN to one with a different EUI / IQN assuming the data on both
targets is identical. Would this be handeled by the iSCSI stack or
multipathd?
Thank you for your help!
