Verifying the existence of two paths: storage array show-config command

You should verify that your Data ONTAP system is configured with two paths to an array LUN so that there is a secondary path in case the primary path fails or is taken offline.

Step

  1. Enter the following command to show the primary and secondary paths to array LUNs: storage array show-config
    You see information similar to the following:
    LUN Group Array Name Array Target Ports    Switch Port Initiator
    Group 0 (4 LUNS) HP_V210 50:00:1f:e1:50:0a:86:6d  vnmc4300s35:11 0b
                             50:00:1f:e1:50:0a:86:68  vnbr4100s31:1  0a
                             50:00:1f:e1:50:0a:86:6c  vnmc4300s35:6  0d
    Group 1(50 LUNS) HP_V200 50:00:1f:e1:50:0d:14:6d  vnbr4100s31:5  0a
                             50:00:1f:e1:50:0d:14:68  vnmc4300s35:3  0d

    This example shows output from a Data ONTAP system that is connected to two storage arrays. Each LUN group consists of LUNs that share the same two paths. Group 0 contains a total of 4 LUNs on the HP_V210 array and Group 1 contains 50 LUNs on the HP_V200 array.

    Array LUNs that are not configured with two paths are shown as one or more LUNs with a single path, similar to the following example.
    LUN Group Array Name Array Target Ports    Switch Port  Initiator
            (4 LUNS) HP_V210 50:00:1f:e1:50:0a:86:6d  vnmc4300s35:11 0b
