WAY 1
1．查看SPG=0 现有的IOG Software Package ，确定现有的IOG Software Package中没有FUNCTION CHANGE 所用的Software Package。
LASYP:SPG=0,VNODE=A;
LASYP:SPG=0,VNODE=B;

2．Start the function change
FCSPI:SPG=0;

3．Specify the nodes to change
FCSLS:LNODE=A&B,RNODE=A&B,RSNODE=A&B;
FCSLS:LNODE=A,RNODE=B,RSNODE=A;! For installation in Node-A !
FCSLS:LNODE=B,RNODE=A,RSNODE=B; ! For installation in Node-B !
3 Load the new software package into the hard disk.
Insert OD into the OD drive and load the software
FCSSL:IONODE=a,IO=OD-1; !7 mins!
wait for printout"SP SOFTWARE LOAD" !7 min!

4．Note this step is optional. Specify the new system name
FCSDL:NEWSYSTEM=new_system_name;
and wait for printout. "SP SYSTEM DESCRIPTION LOAD"
The system name can be according to a market naming convention.

5．Load the system description file.
Leave optical disk in the drive and load the system description file and wait for printout.
Remove the OD from the drive after the loading has finished.
FCSDL:IONODE=A,IO=OD-1;!5 mins!
"SP SYSTEM DESCRIPTION LOAD"

6．Note this step is only neccessary
if a "new_system_name" was given at Step 4.
Change the deferred constant which contains the new system name.
Give command and wait for printout.
FCSDL:MODULE=NASLIB,DEFC=INSTALLNAM,STRING=new_system_name;

7．Print the hardware table and take a logfile of the printout.
IMLCT:SPG=0;
IMHWP:NODE=A;
IMHWP:NODE=B;
END;

8．Save the system file on the harddisk if FC is performed from an AT-terminal.
DO NOT GIVE COMMAND LASYP UNTIL PRINTOUT IS RECEIVED. Otherwise the
Function Change might fail.
FCSSI:FCTYPE=1; !1 hour! "SP FUNCTION CHANGE"
NOTE:FCTYPE=1 gives a reload in the EX-node and two reloads in the SB-node. The B Node will be in state DIAGNOSING and will go later to UPDATING LARGE.The large update will take approx. 1 hour.The reloads of the nodes will lead to an alarm. Wait for printout on the alarm terminal“ SP LINK FAULT”This alarm will be ceased after approx. 10 min.
The B Node will be deblocked automatically.
Check with command that the SB node deblocks automatically to update large
IMMCT:SPG=0;
IMCSP;
END;
When the result printout (FCSSI) shows EXECUTED, continue with the next step In case that the result printout shows FAILED, continue with chapter，"FC function change failed"

9．End the Function Change.
Wait for the answer printout.
FCSPE;
"SP FUNCTION CHANGE ENDED"

10．Check that SB node goes
"UPDATING LARGE"
IMMCT:SPG=0;
IMCSP;
END;
