It was not know at the time the first attempt to add the disk that it was not visible on some of the clustered nodes.

Therefore the 1st attempt failed:

Despite of the above error/failure, the ASM disk header of the disk was updated as a member of the ASM disk group by the nodes where the disk was visible.
However, the ASM metadata still is unaware that the disk is fully part of the ASM disk group, nor data has been moved to the new disk. Hence, the disk is truly not part of the ASM disk group.
