Changing iSCSI target setting

Use LUN Manager to change the name or host mode of a iSCSI target. You can change only the host mode option of the host group for the initiator port. You cannot use this procedure on the host group for the external port.

• Before changing the host mode of an iSCSI target, you should back up data on the port to which the iSCSI target belongs. Setting host mode should not be destructive, but data integrity cannot be guaranteed without a backup.

• When a secret is changed two times or more for the same iSCSI target successively, perform the next change after waiting for the completion of the task that has been applied. If the secret is changed without waiting for the completion of the task that has been applied, the user name which you expected to be changed can not be incorporated.
