Abstract
A method for maintaining data integrity of a storage device is provided. A request is received to create an access monitoring session for a data range on a volume of the storage device. A session identification (ID) is determined for the access monitoring session for data range on the volume. An entry is created in an access monitoring session table for the session ID, and the entry adds the access monitoring session with session ID for the data range on the volume to the access monitoring session table. Request parameters are included in the request to create the access monitoring session. The request parameters denote access to the data range on the volume for the session ID and are stored in the access monitoring session table. Access is controlled to the data range on the volume for the session ID based on request parameters stored in the access monitoring session table.
