I have enabled the front end ports of vplex, but when ii check the port status it shows No-Link. Can any one help in letting me know how to enable the ports and assign the wwn's.
No-link means that the port is enabled, but doesn’t have connectivity. This could be because there is no cable plugged in or any number of problems that result in the VPLEX port not seeing a link.
You can do a listing of the sfps context (ls /engines/**/sfps) and check the RxPower column. This context contains information from the port SFP modules. The RxPower numbers should generally be about 300 or more. Ports may work with lower numbers, but you want the numbers to be in the 300+ range. I believe any numbers below the 200 range will cause a dial home.
I have seen where cables aren’t inserted fully or are dirty and it causes problems.
