Server migration-server rename with ISCSI connection to volume--possible issue.

I'm using Nimble connection manager within a virtual server to connect to volumes.  During a server migration, I configured 3 ISCSI volumes to the Nimble SAN via IP and IQN name.  After the migration, I renamed the server name.  Everything is working fine.  However, afterwards, I noticed that the initiator name has changed on the server with the server rename.  In my Nimble volume configuration, I configured for IQN and IP address in which the IQN is different from the actual server since the server rename.  I would think this would break the ISCSI connection, but it has not.  Should I be concerned that something might happen in the future that it will break?  I'm wondering if I should disconnect the volumes, reconfigure the Initiator name on the SAN or server, then reconnect the volumes or leave it be?  Maybe I just don't understand how ISCSI makes the connection to the volume.  Comments.  Thanks.

Example:

SAN Initiator group configuration:

IQN:  iqn.1991-05.com.microsoft:servername-2012r2.city.st

IP address:    10.10.10.1

Virtual Server Configuration:

IQN:  iqn.1991-05.com.microsoft:servername.city.st

IP address:   10.10.10.1

Hello,

Yes, absolutely disconnect and reconnect. Ensure you have the new iqn added to the initiator group before doing this.

iqn's are only authenticated at the point at which they login, this is a frequent issue we get in support. Customers only find out when there is a controller failover or they reboot their hosts.

Another area to be careful is capitalisation of iqn's, they are case sensitive.

Many thanks,

Chris
