Before you configure or remove device nodes, be sure to first identify the fabric devices by using the procedure Ensuring That LUN Level Information Is Visible.
In this example, an Ap_Id on a fabric-connected host port is a path to the Sun StorageTek Traffic Manager software device. For example, all devices with a path through c2 are to be configured, but none through c0 are to be configured. c2 is an attachment point from the host to the fabric, whereas c2::50020f2300006107 is an attachment point from the storage to the fabric. A host detects all the storage devices in a fabric for which it is configured.
Configuring an Ap_Id on the device that has already been configured through another Ap_Id results in an additional path to the previously configured device. A new device node is not created in this case. The device node is created only the first time an Ap_Id to the corresponding device is configured.
Log in as root (su - root)..
Identify the fabric-connected host port to be configured.

Devices represented by Ap_Ids c0::50020f2300006077 and c2::50020f2300006107 are two paths to the same physical device, with c0::50020f2300006077 already configured. Configure the unconfigured devices on the selected port. This operation repeats the configure command of an individual device for all the devices on c2. This can be time-consuming if the number of devices on c2 is large.
# cfgadm -c configure c2 |
Verify that all devices on c2 are configured.

Notice that the Occupant column of c2 and all of the devices under c2 is marked as configured.
The show_SCSI_LUN command displays FCP SCSI LUN information for multiple LUN SCSI devices. The following code example shows that the physical devices connected through by c2::50020f2300006107 and c2::50020f2300005f24 each have two LUNs configured.
