Know more About The zoning problem
The identification and monitoring of a node in the Fibre Channel SAN usually fail if this is located in a different zone than the management agent since in this situation direct access is no longer permitted. This problem can be rectified by the setting up of special management zones, the placing of a management agent in several zones or the placing of further management agents. The Fibre Channel protocol, however, has an even more elegant method of solving this problem. It defines services that permit the collection or entering of information. A management agent is capable of requesting the necessary information about these services, since these are not affected by the zoning problem. Two examples are:
• Platform registration This service is offered by the fabric configuration server and makes it possible for an end node, such as a server or a storage device, to enter information about itself in the configuration server.
• End point node information This is a new proposal for the Fibre Channel protocol, which was entered under the name of fabric device management interface and which allows the fabric itself to collect information about the properties and state statistics via ports.
