The WWPN value is hidden in Webclient for vPLEX Storage array

Products

• VMware vCenter Server

Issue/Introduction

Symptoms:

• WebClient and HTML5 client show different Target values under Storage paths.
• When logged into WebClient, only 16 digit WWNN values are displayed under ESXi -> Configure -> Storage Adapters -> Select vmhbax -> Paths -> Target, ignoring WWPN values.
• This issue is observed only with vPLEX Storage arrays.
• Non-vPLEX Storage array shows both the WWNN and WWPN under Paths -> Target field.
• In Web client, the WWPN filed is blank and when connected using HTML5 client, the Target field shows WWNN and a random value in place of WWPN.

Note: The command line output will give you the correct WWNN and WWPN details via SSH / ESXi shell.
For example:
# esxcli storage core adapter list
