Could not create NetworkPortal in configFS issue resolved

I see that there is an error while creating iscsi portal ” Could not create NetworkPortal in configFS ” in Red hat enterprise Linux 7. I have installed targetcli, started services targetcli and created block storage, LUN, iscsi internet name. 

After creating all this i was trying to create an portal but it through an error ” could not create NetworkPortal in configFS “

i find no clue after few minutes i observe that there is an default portal has been created with 0.0.0.0:3260, i thought that was not created by me and i was trying to delete default port with 0.0.0.0:3260. See the Guide to create iscsi server
