CMMVC8570E: A subsidiary volume may only be mapped to hosts of type adminlun.

Explanation

An attempt was made to map a subsidiary volume to a host that wasn't an adminlun type. Subsidiary LUN mappings are typically created or removed by the Spectrum Control Base application. These mappings apply only to adminlun host types, and so it is unlikely that a storage administrator would encounter this message.
