OceanStor Dorado5000 V3 - PR site storage can't see the target replication LUN on the DR site storage

The PR site storage can't see the target replication LUN on the DR site storage.

[Root cause]

For the standby LUN on the DR site, you have assigned it to some hosts.

However, this is a overt restrict in our protection. For the target replication LUN, you shouldn’t assign it to any host. More details, please refer to our production document.

[Solution]

Remove this remote replication target LUN from the current LUN group to channel the mapping relation with other hosts. Then re-create the remote replication pair again - it succeeds to scan the target replication LUN on the PR site.
