In Example 7-10 the XCLI commands show that the target called ITSO_DS4700 has two ports,one from controller A (201800A0B82647EA) and one from controller B (201900A0B82647EA).This is not the correct configuration and should not be used.Example 7-10 Incorrect definition, as target has ports to both controllers>> target_listName SCSI Type ConnectedITSO_DS4700 FC yes>> target_port_list target=ITSO_DS4700_Ctrl_BTarget Name Port Type Active WWPN iSCSI Address iSCSI PortITSO_DS4700 FC yes 201800A0B82647EA 0ITSO_DS4700 FC yes 201900A0B82647EA 0Instead, two targets should have been defined, as shown in Example 7-11.

To display the profile from the DS StorageManager choose Storage Subsystem View Profile All. Then go to the bottom of theProfile panel. The profile may vary according to NVRAM version. In Example 7-12 select thehost type for which ADT status is disabled (Windows 2000).Example 7-12 Earlier NVRAM versionsHOST TYPELinuxWindows 2000/Server 2003/Server 2008 Non-ClusteredADT STATUSEnabledDisabledIn Example 7-13 choose the host type that specifies RDAC (Windows 2000).Example 7-13 Later NVRAM versionsHOST TYPELinuxWindows 2000/Server 2003/Server 2008 Non-ClusteredFAILOVER MODEADTRDAC228 IBM XIV Storage System: Copy Services and Migration
