BUG
When attempting to recalculate or change the spatial index for a feature class with archiving enabled, the command can fail when attempting to change the archive feature class from load_only mode to normal_io mode.
The cause of the problem is that the process that moves a SDEBINARY layer from load_only mode to normal_io mode does not detect that the layer being modified is an archive feature class. The process attempts to place a unique index on the archive class shape attribute, which fails if any features have been archived since archiving was initialized (because of duplicate shape values).
