适用场景

ONTAP 9

问题描述

  • LUN处于联机状态、已映射且位于System Manager或CLI

    示例中所示的预期节点上:

cluster1::> lun show -path /vol/vol_linux/lun1 -fields vserver,path,state,mapped,node
vserver   path         state  mapped node
--------- ------------------- ------ ------ -----------
svm_linux /vol/vol_linux/lun1 online mapped cluster1-03

  • igroup具有SLM和端口集

    示例:

cluster1::> lun mapping show -path /vol/vol_linux/lun1  -fields vserver,path,igroup,portset,reporting-nodes
vserver   path         igroup    portset reporting-nodes
--------- ------------------- ----------- ------- -----------------------
svm_linux /vol/vol_linux/lun1 linux_iscsi test   cluster1-03,cluster1-04

 

  • 端口集包含LIF

    示例:

cluster1::> portset show
Vserver   Portset    Protocol Port Names        Igroups
--------- ------------ -------- ----------------------- ------------
svm_linux test      mixed   iscsi_1-1, iscsi_1-2, iscsi_2-1, iscsi_2-2
                             linux_iscsi

 

  • LIF不在用于SLM的同一节点上(报告节点)

    示例:

     
    cluster1::> net int show -vserver svm_linux -data-protocol iscsi  -fields lif,curr-node
      (network interface show)
    vserver   lif     curr-node
    --------- --------- -----------
    svm_linux iscsi_1-1 cluster1-01
    svm_linux iscsi_1-2 cluster1-01
    svm_linux iscsi_2-1 cluster1-02
    svm_linux iscsi_2-2 cluster1-02
