In my lab environment I used iscsi as my shared storage. Today I have removed network adapters from software iscsi adapter to do some other networking stuff. After a while when im trying  to reconfigure iscsi im getting below error


Call ïscsimanager.query candidatenics"



To resolve this problem I had to reset iscsi from esx shell by following below steps


find iscsi config locations









navigate to the iscsi config location /etc/vmware/vmkiscsid




Delete all the files & reboot esx host
