Issue/Introduction

This article explains using tools to determine LUN pathing information for ESXi hosts.

For information troubleshooting LUN connectivity issues, see Troubleshooting LUN connectivity issues on ESXi host


Environment

VMware vSphere ESXi 7.0.0
VMware vCenter Server 6.7.x
VMware vSphere ESXi 6.7
VMware vCenter Server 6.0.x
VMware vCenter Server 6.5.x
VMware vCenter Server 7.0.x
VMware vSphere ESXi 6.5
VMware vSphere ESXi 6.0

Resolution

There are two methods used to obtain the multipath information from the ESX host:
  • ESXi command line – use the command line to obtain the multipath information when performing troubleshooting procedures.
  • vSphere Client/vSphere Web Client – use this option when you are performing system maintenance.

 

ESXi Command line
 
To obtain LUN multipathing information from the ESXi host command line:
  1. Log in to the ESXi host console.
  2. Type esxcli storage core path list to get detailed information regarding the paths.

    For example:

    fc.5001438005685fb7:5001438005685fb6-fc.5006048c536915af:5006048c536915af-naa.60060480000290301014533030303130
    UID: fc.5001438005685fb7:5001438005685fb6-fc.5006048c536915af:5006048c536915af-naa.60060480000290301014533030303130
    Runtime Name: vmhba1:C0:T0:L0
    Device: naa.60060480000290301014533030303130
    Device Display Name: EMC Fibre Channel Disk (naa.60060480000290301014533030303130)
    Adapter: vmhba1
    Channel: 0
    Target: 0
    LUN: 0
    Plugin: NMP
    State: active
    Transport: fc
    Adapter Identifier: fc.5001438005685fb7:5001438005685fb6
    Target Identifier: fc.5006048c536915af:5006048c536915af
    Adapter Transport Details: WWNN: xx:xx:xx:xx:xx:xx:xx:xx WWPN: xx:xx:xx:xx:xx:xx:xx:xx
    Target Transport Details: WWNN: <WWNN> WWPN: <WWPN>

     
  3. Type esxcli storage core path list -d naaID to list the detailed information of the corresponding paths for a specific device.
     
  4. The command esxcli storage nmp device list lists the LUN multipathing information:

    naa.60060480000290301014533030303130
    Device Display Name: EMC Fibre Channel Disk (naa.60060480000290301014533030303130)
    Storage Array Type: VMW_SATP_SYMM
    Storage Array Type Device Config: SATP VMW_SATP_SYMM does not support device configuration.
    Path Selection Policy: VMW_PSP_FIXED
    Path Selection Policy Device Config: {preferred=vmhba0:C0:T1:L0;current=vmhba0:C0:T1:L0}
    Path Selection Policy Device Custom Config:
    Working Paths: vmhba0:C0:T1:L0


    Notes:

vSphere Client HTML5 and Web Client

To obtain multipath settings for your storage in the HTML5 client:

  1. Select an ESXi host, and click in the Configure tab.
  2. Click in Storage Devices.
  3. Select a the storage device that you want to verify.
  4. Scroll down in the Properties tab and click in "Edit multipathing...".
