Symptoms
The phys-path properly in zfs vdev labels can be mismatched with the actual device path of LUNs.
A mirrored rpool is created by 2 luns.
# zpool status rpool
pool: rpool
state: ONLINE

From luxadm, 2 luns are each connected to qlc@2 and qlc@1 respectively.

The label on the other disk looks the same as this one.
The phys_path on the label shows that both luns are on qlc@1
