Issue

FCP initiator show doesn't show all active sessions

  • From the host end, all paths can be seen properly and seem to be functioning as per multipath -ll output.
[root@XXXX ~]# multipath -ll

  • fcp initiator show does not show all the sessions to all the nodes.

NetApp::*> fcp initiator show

igroup show -v may not show all the session either for fc initiators. 

  • However, running fcp initiator show -node node_name shows all the sessions as expected.
