Updating the Object Data Manager (ODM) stanzas for the system iSCSI devices requires that you follow certain guidelines.
An interim fix is available to update the AIX ODM stanzas to recognize iSCSI system volumes.
Ensure that you have installed the official PTFs. The following website provides information about the available PTFs:
