Abstract
A storage array is configured with an allowed process configuration. An allowed process may correspond to an application or process executed by a host computing system that may seek to access a volume of the storage array via a command descriptor block message or a corresponding block command message, which may comprise a data field and a metadata field. The host may embed a process identifier corresponding to a process seeking to access the storage array in the metadata field. The storage array may receive the block command message and determine whether the metadata field comprises a process identifier that is included in the allowed process configuration. If so, the storage array may perform the access command corresponding to the block command message. If not, the storage array may reject performing the access command. The storage array may report access commands that were performed or rejected.
