Truenas replication and recover

i have zfs volume which is connect to iscsi on my esxi server.
i replicate zfs volume to another truenas server. i fail my first truenas server and recover on another trunas server through clone. when i connect to iscsi esxi server zfs volume connect to iscsi esxi server . it shows in storage-devices but not shown in datastore automatically. when i try to create datastore its format the device and i lost my data.

Make sure the iSCSI settings are exactly the same in the replicated system.
