Your customer complains that u host will constantly report losing a connection to the iSCSl...

IQN stands for iSCSI Qualified Name, which is a unique identifier for an iSCSI initiator or target1.

ONTAP uses IQN to authenticate and authorize iSCSI sessions2.

If two hosts have the same IQN, they will cause a conflict and ONTAP will reject the new session request from the second host3.

This will result in the host losing the connection to the iSCSI target and then reporting that the session was reestablished, as shown in the exhibit.

To avoid this problem, each host should have a unique IQN. References:
