the WWN cards to see if they reflect the status of the components.
Note: The LEDs may take up to two minutes after WWN card installation to
begin functioning.

comparing the output with the original
supportsave data.
v licenseIdShow
v ipAddrShow
v switchName
v chassisName
v wwnCardShow ipdata
v chassisShow
(look at the WWN and chassis information at the bottom)
v ficonShow switchrnid
9. Run the
switchcfgpersistentenable
command to persistently enable each
logical switch that was disabled before removing the WWN cards.
switch:FID128:root> switchcfgpersistentenable
Switch’s persistent state set to ’enabled’
10. Pack the faulty WWN cards in the packaging provided with the new cards for
return to IBM for failure analysis, following local procedures.
