To Ensure LUN Level Information is Visible

1. Use the cfgadm command to identify LUN level information.

   If you issue the cfgadm -al -o show_SCSI_LUN controller-ID command immediately after a system boots up, the output might not show the Fibre Channel Protocol (FCP) SCSI LUN level information. The information does not appear because the storage device drivers, such as the ssd and st driver, are not loaded on the running system.

2. Use the modinfo command to check whether the drivers are loaded. After the drivers are loaded, the LUN level information is visible in the cfgadm output.
