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
- 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
