Creating On-Demand Device Nodes on Hosts for Fabric Configurations

In SL zones, hosts and storage devices connect in private loop topology, and devices are available by default when devices are added to an SL zone. With the Sun StorEdge Traffic Manager software enabled, the Solaris host configures the devices as Sun StorEdge Traffic Manager devices.

The discussion of on-demandnode creation in these sections applies to Fabric devices such as an array connected to a host through a switch (a host port connected to an F_port and an array connected to a TL_port).

Creating Device Nodes Without the Sun StorEdge Traffic Manager Software Enabled

This section describes Fabric device configuration tasks on a host that does not have the Sun StorEdge Traffic Manager software enabled.

The procedures in this section use specific devices as examples to illustrate how to use the cfgadm(1M) command to discover and configure Fabric devices.

The devices attached to the Fabric-connected host port are not configured by default, thus those devices are not available to the Solaris host. Use the cfgadm(1M) configure and unconfigure commands to manage device node creation for Fabric devices. See the cfgadm_fp (1M) man page for additional information.

The procedures in this section illustrate how to discover Fabric devices which are visible on a host and to configure and make them available to a Solaris host.

The device information that you supply, and is displayed with the cfgadm(1M) command, depends on your system configuration.
