Note: If the scriptvwwnn command has been used previously, the adapter continues
to use that WWPN until you change the WWPN with the restorenvwwn
command.
To change WWPN words 0 and 1 from the command line, type (all in one line)
oslpcfg scriptwwpn n=<adapter number> w0=<wwpn word 0> w1=<wwpn word
1>
The following example updates the non-volatile WWPN word 0 word 1 for adapter #1:
oslpcfg scriptwwpn n=1 w0=20A2D6B8 w1=C920A1B2
Updating Volatile WWNN (scriptvwwnn)
This command reads the WWNN words 0 and 1 from the command line to update the
volatile WWNN. When next discovered, the adapter uses this new WWNN. It does not
use the original IEEE address assigned by manufacturing (located in Configuration
Region 16 or 32) nor does it use the value entered by the writewwn or scriptwwnn
commands.
If the adapter does not have firmware that supports the volatile WWN, the following
error message appears:
Write Volatile Parms Error. Reported Error 48
If this occurs, install firmware that supports the volatile WWN.
Notes:

Word 0 of WWNN and WWPN names must follow one of the following
formats:
1 0 0 0 0 x x x
2 x x x x x x x
3 x x x x x x x
5 x x x x x x x

Once you issue this command, the volatile WWNN is used by the adapter until
the restorenvwwn command is issued or the system is restarted.
Caution: Use the scriptvwwnn command with caution. If you use the same volatile
WWNN on more than one adapter in a fabric, unpredictable results may
occur.
To change volatile WWNN words 0 and 1 from the command line, type (all in one line)
oslpcfg scriptvwwnn n=<adapter number> w0=<wwnn word 0> w1=<wwnn word 1>
The following example updates the volatile WWNN word 0 word 1 for adapter #1:
oslpcfg scriptvwwnn n=1 w0=20A2D6B8 w1=C920A1B2
