How to Ensure LUN Level Information is Visible

1. Become an administrator.
2. Identify the LUN level information.

   # cfgadm -al -o show_SCSI_LUN

   If you issue the cfgadm -al -o show_SCSI_LUN controller-ID command immediately after a system boots, 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 yet on the running system.

3. Determine whether the drivers are loaded.

   For example:

   # modinfo | grep ssd

   After the drivers are loaded, the LUN level information is visible in the cfgadm output.
