Hello Phany,
There are two ways for this:
1. The value of iSCSI Initiator Node Name of the host is changed. For the iSCSI connection, change the name of the initiator to the changed iSCSI Initiator Node Name value on the disk array.
2. A Fibre Channel (FC) host bus adapter (HBA) is replaced. For the FC connection, add the WWN of the corresponding host as the current host port WWN on the disk array.
Thanks.
