Attached hosts see only the SFI, as shown in Example 7-2. dscli>  lssu Date/Time: September 26, 2019 9:18:11 AM CEST IBM DSCLI Version: 7.9.0.482 DS: - Name ID Model WWNN pw state ===================================================== - IBM.2107-75xxxx0 996 5005076309FFE962 On Example 7-2 Machine WWNN Determining a WWPN by using a DS CLI  Similar to the WWNN, a WWPN in the DS8900F looks like the following address: However, the DS8900F WWPN is a child of the SFI WWNN, where the WWPN inserts the  z and  x:xx  values from SFI WWNN. It also includes the  YY:Y , from the logical port naming,  which is derived from where the host adapter is physically installed. Use the DS CLI  command  lsioport  to determine the SFI WWPN, as shown in Example 7-3. 50:05:07:63:0z:YY:Yx:xx Example 7-3 WWPN determination dscli>  lsioport Date/Time: September 26, 2019 9:20:47 AM CEST IBM DSCLI Version: 7.9.0.482 DS: IBM.2107-75xxxxx ID WWPN State Type topo portgrp  Security =========================================================================================== I0030 5005076309031962 Communication established Fibre Channel-SW SCSI-FCP 0 Disabled I0031 5005076309035962 Communication established Fibre Channel-SW SCSI-FCP 0 Disabled I0032 5005076309039962 Communication established Fibre Channel-SW SCSI-FCP 0 Disabled I0033 500507630903D962 Communication established Fibre Channel-SW SCSI-FCP 0 Disabled I0100 5005076309081962 Communication established Fibre Channel-SW SCSI-FCP 0 Disabled I0101 5005076309085962 Communication established Fibre Channel-SW SCSI-FCP 0 Disabled I0102 5005076309089962 Communication established Fibre Channel-SW SCSI-FCP 0 Disabled I0103 500507630908D962 Communication established Fibre Channel-SW SCSI-FCP 0 Disabled I0230 5005076309131962 Offline Fibre Channel-LW - 0 Disabled I0231 5005076309135962 Offline Fibre Channel-LW - 0 Disabled I0232 5005076309139962 Offline Fibre Channel-LW - 0 Disabled I0233 500507630913D962 Offline Fibre Channel-LW - 0 Disabled I0300 5005076309181962 Offline Fibre Channel-LW - 0 Disabled I0301 5005076309185962 Offline Fibre Channel-LW - 0 Disabled I0302 5005076309189962 Offline Fibre Channel-LW - 0 Disabled I0303 500507630918D962 Offline Fibre Channel-LW - 0 Disabled Determining a WWNN by using a DS GUI Use the following guidelines to determine the WWNN by using the Storage Management GUI: https://<  hmc IP address  > 1.
