9.1 TotalStorage Productivity Center component interaction This section discusses the interaction between IBM TotalStorage Productivity Center for Fabric and the other IBM TotalStorage Productivity Center components. IBM TotalStorage Productivity Center interaction includes external products and devices. IBM TotalStorage Productivity Center for Fabric uses standard calls to devices to provide and gather information to enable it to provide information about your environment. 9.1.1 IBM TotalStorage Productivity Center for Disk and Replication Base When a supported storage area network (SAN) Manager is installed and configured, IBM TotalStorage Productivity Center for Disk and IBM TotalStorage Productivity Center for Replication leverages the SAN Manager to provide enhanced function. Along with basic device configuration functions, such as logical unit number (LUN) creation, allocation, assignment, and deletion for single and multiple devices, basic SAN management functions such as LUN discovery, allocation, and zoning are provided in one step. In Version 2.1 of TotalStorage Productivity Center, IBM TotalStorage Productivity Center for Fabric is the supported SAN Manager. The set of SAN Manager functions that are exploited are: The ability to retrieve SAN topology information, including switches, hosts, ports, and storage devices. The ability to retrieve and to modify the zoning configuration on the SAN. The ability to register for event notification -- this ensures that IBM TotalStorage Productivity Center for Disk is aware when the topology or zoning changes as new devices are discovered by the SAN Manager, and when host LUN configurations change.
