SM-BC目标集群LUN未连接到Linux主机

• ONTAP 9
• SnapMirror业务连续性(SM-BC)
• Linux Unified Host Utilities (LuHu)
• iSCSI
• CentOS 7.

• SM-BC目标LUN映射到ONTAP中的正确igrop。
• multipath -ll 显示主机上一半的预期路径、在本示例中为4、共8条：

3600a0980774f6a34495d544d47387373 dm-2 NETAPP  ,LUN C-Mode

• Luhu's sanlun lun show -p 仅显示 源集群上Lifs的路径：

           ONTAP Path: svm_linux:/vol/centos1/centos1_1

            LUN Size: 10g
            Product: cDOT
