2. Determine the workstation’s LAN ID using the lanscan command by entering
the following:
/usr/sbin/lanscan
The output is similar to the following:
Hardware Station Dev Hardware Net–Interface NM Encapsulation Mjr
Path Address lu State NameUnit State ID Methods Num.
2.0.2 0x0800970ECC0 0 UP lan0 UP 4 ETHER 52
After you install the new tray assembly and power on the system for the first
time,youwillbepromptedforthe LANID. Recordthatinformation heresoyou
