Abstract

This article automatically finds and creates a zone with device that supports power management. This power management zone is necessary, since only devices in the same zone can discover each other and send a power management command.

Zoning For SCSI Power Management Devices

This article describes new, different, and unique ways for power management, which includes the use of Fibre Channel name server registration and name server queries. There are two new novel parts to this article (a) a new name server object and (b) a new discovery process to discover devices that support power management. Two new name server commands are invented to obtain the information needed about devices that support power management. These new commands and the information about the new name server object are described in Figure 1 and 2. In the processes described in Figures 3 and 4, a device named the management server is used, and new management server commands and objects are created.

Figure 1: Registration Process for Devices that Support Power Management

In Figure 1, process 100 uses Fibre Channel port login and name server registration. Every fibre channel device is required to register it's name in the name server, as well as the type of protocol it supports. Steps 102 and 104 comprise Fibre Channel name server registration. In step 106, a new type of object is created and this object is used in a new name server command to register that this port supports power management. There are many different names for object or commands that could be used; however, for the purposes of this article, a new name server object is created and it is called power management. In addition, two new name server commands are created: (a) to query the power management object and (b) to register the fact that a device supports power
