        Question:       How do I set up the /etc/system file for Sun Leadville driver                                                  
        Environment:    Host adapter: Sun X6768A / QLA2342                                                     
        Environment:    Host adapter: Sun X6767A / QLA2310                                                     
        Environment:    Driver: Sun Leadville                                                  
        Environment:    Driver: SAN 4.2                                                
        Environment:    OS: Solaris                                                    
        Environment:    EMC SW: PowerPath                                                      
        Problem:        PowerPath cannot see devices after host reboot                                                 
        Problem:        After rebooting the server, the devices are visible in a format, however, a powermt config / powermt restore needs to be run to bring the devices under PowerPath control                                                      
        Change:         Host reboot                                                    
        Root Cause:     The /etc/system file has not been properly setup for the ssd driver.                                                   
        Fix:    Add the following entries to the /etc/system file to ensure that the devices are probed on reboot so they are available for powerpath discovery, do not include the quotes:

'forceload drv/ssd'
'set fcp:ssfcp_enable_auto_configuration=1'
'set ssd:ssd_max_throttle=20'
'set ssd:ssd_io_time=0x3c'   
        Notes:  The above settings are required for both qlc driver and emlxs driver.
