Use the following procedure on Solaris 10 to verify that your Sun StorageTek 4Gb Fibre Channel (FC) Dual-Port ExpressModule (EM) is connected correctly to the attached storage.
Enter the following command:
# cfgadm -a1
If the StorageTek FC EM is properly installed and storage is connected properly, you should see output similar to that shown below. In this example, one port of an EM adapter is connected through a fabric switch to two ports of a disk array.
If a StorageTek FC EM is shown as unconfigured, enter the following command to configure it:
# cfgadm -c configure
