The offline utility prompts you to enter new data:

WWPN word 0

WWPN word 1

WWNN word 0

WWNN word 1
The following example writes the WWPN and WWNN for adapter #1.
oslpcfg writewwn n=1
Enter or Scan value for WWPN word 0 now
Enter a value.
10000000
The system echoes what you entered, followed by the next prompt:
10000000
Enter or Scan value for WWPN word 1 now
Saving WWN data to a file (savewwn)
This command reads the original words 0 and 1 of the IEEE address, installed by
manufacturing, from configuration regions 16 (or 32) of the adapter (specified by its
number) and saves the configuration region information in the selected WWN file.
To save the WWN data to a file, type
oslpcfg savewwn n=<adapter number> c=<wwn filename>
The following example reads the configuration region information on adapter #4 and
saves it to the contents of the ctwwn.sav file:
oslpcfg savewwn n=4 c=ctwwn.sav
Restoring WWN and Updating NVPARMS (restorewwn)
This command restores words 0 and 1 of the IEEE address from a specified file created
with the savewwn command and uses them to update the NVPARMS port name with
this IEEE address.
To restore the WWN, type
oslpcfg restorewwn n=<adapter number> c=<wwn filename>
The following example updates the NVPARMS on adapter #4 with the ctwwn.sav file.
oslpcfg restorewwn n=4 c=ctwwn.sav
Restoring NVPARMS (restorenvwwn)
This command restores the non-volatile WWPN and WWNN to the adapter, replacing
any volatile WWPN and WWNN data, without powering off the adapter.
If the adapter does not have firmware that supports the volatile WWN, the following
error message appears:
Write Volatile Parms Error. Reported Error 48
