Hi,
you can register the initiators using Navisphere CLI
you can try the below steps from the example for iSCSI
iSCSI connection
On array1 (array uid 123) (SPA IP 1.2.3.4)
naviseccli –h 1.2.3.4 - user < > -password < > -scope 0 connection –addset -name mv_iscsi_connection_to_456
naviseccli –h 1.2.3.4 - user < > -password < > -scope 0 connection –addpath –name mv_iscsi_connection_to_456 –target –sp a –portid < MV ISCSI port ID on 123 array’s SPA>
naviseccli –h 1.2.3.4 - user < > -password < > -scope 0 connection –addpath –name mv_iscsi_connection_to_456 –target –sp b –portid < MV ISCSI port ID on 123 array’s SPB>
On array 2 (array uid 456)(SPA IP 5.6.7.8)
naviseccli –h 5.6.7.8 - user < > -password < > -scope 0 connection –addset -name mv_iscsi_connection_to_123
naviseccli –h 5.6.7.8 - user < > -password < > -scope 0 connection –addpath –name mv_iscsi_connection_to_123 –target –sp a –portid < MV ISCSI port ID on 456 array’s SPA>
naviseccli –h 5.6.7.8 - user < > -password < > -scope 0 connection –addpath –name mv_iscsi_connection_to_123 –target –sp b –portid < MV ISCSI port ID on 456 array’s SPB>
Run the following command to see the new connection:
naviseccli –h 1.2.3.4 - user < > -password < > -scope 0 connection –getset
Run the following command to enable mirroring between the arrays using the connection sets:
naviseccli –h 1.2.3.4 -user … -password … -scope … mirror –enablepath -connectiontype iscsi
Thanks

What flare release is running on the CX4?
If you go to the iSCSI ports you can select the port that you're trying to connect with and select ping - then ping to the other array. In Navisphere right click on the array and select Port Management, then select the iSCSI port and click ping at the bottom of the sceen - in the Source dropdown, select the IP address on that array and then select the remote array IP in the Dest dropdown.
In Unisphere on the left hand side select Manage Data Ports and do the same as above.

In the Manage Data Ports which iSCSI ports are listed as Mirrorview?

hello Glen all those tests were completed successfully, my problem is that when looking and running
the option "manage mirror conection" (between last port iscsi both storages), the process is not completed. i received the error. "the attached array speciefied was not found or had no valid ports to enable disable 0x1".
troubleshootings steps executed were:
--- update flare to the last version available (525)
--- restart management server both storage,
--- delete and create again iscsi connection between storage system

Are you adding the connections between systems manually or using the Wizard? In the Connections between systems do you see both SPA and SPB ports? You have one Connection Name and that has the two SP ports on the other array? In the Manage Connections are you seeing the connection in the left-hand window and what is the Status and Logged-In Status?

Hi,
Since they are showing as not logged, Ensure cabling and routing is fine, there is no firewall between Primary and Secondary. Also make sure that you are able to telnet and identify port 3260 is not blocked between the two Arrays.

Hi,
May i know, how you are accessing the Arrays ? (RA) ?
if there is a link between the Arrays, then you can see the status as Logged In (identify if the cable is faulted or cable is connected to correct iSCSI port)
it is recommended to have iSCSI commnunication in a different subnet rather than Management subnet.
there is no telnet option available in Navisphere or Unisphere, you can try and verify telnet to 3260 port from a host that belong to iSCSI subnet.
Thanks

good point Ganapa
i tryied accessing SPs via RA, and from the dos prompt, i did not find the telnet command. any idea.
questions:
-- can i do the register of the array as the way i register a host server?
-- segment and switch rules isolate i think so, comunication between iscsi ip addresses (both arrays) and management ip addresses (both arrays)
is that correct?
thank you
