Updating ODM stanzas for system iSCSI devices

Updating the Object Data Manager (ODM) stanzas for the SAN Volume Controller iSCSI devices requires that you follow certain guidelines.

Before you begin

An interim fix is available to update the AIX® ODM stanzas to recognize iSCSI SAN Volume Controller volumes.

Ensure that you have installed the official PTFs. The following website provides information about the available PTFs:

www.ibm.com/support

When you install the interim fix package, the AIX host can recognize iSCSI SAN Volume Controller volumes. The SAN Volume Controller volumes are shown with the following attributes in Figure 1 for lsdev -C -1 hdisk1.
