Did you reboot the host once post re-connecting the disk? If the disk was abruptly removed, the processes running on that datastore would have gone hung and have to be killed for the datastore to be mounted back.

Yeah, Many times, But the problem still exists.

Why in ESXi 6.7, We don't have an option to add exist datastore like past versions?

Did you already check whether the steps in the "Command line" section of https://kb.vmware.com/s/article/1011387​ will help.

I had umount and deleted one of the other datastore to test this problem, Becuase one of the drives have a problem.

But the other datastore is OK and i can't mount it too, Actually there is no choice for chosing vmfs without create partition in this version.
