Learn how VMware Skyline Advisor and Skyline Health Diagnostics work together to provide proactive intelligence and self-service log analysis.

Use Skyline Advisor to avoid issues before they occur across VCF, vSphere, vSAN, NSX, vROps & Horizon. Skyline Findings are based on top KBs, VMSAs/CVEs and design best practices.

Use Skyline Health Diagnostics to root cause vSphere & vSAN logs when an issue occurs. Skyline Health Diagnostic Findings are based on top KBs and VMSA/CVEs. You can use the Skyline Health Diagnostics tool in online or offline mode.

If you require additional help from technical support, please use Skyline Advisor to initiate a Log Assist to reduce time to upload logs. TSEs can also initiate logs to reduce effort.

Purpose

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

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:

Log in to the ESXi host console.

Type esxcli storage core path list to get detailed information regarding the paths.

For example:

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>

Type esxcli storage core path list -d naaID to list the detailed information of the corresponding paths for a specific device.

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:

For information on multipathing and path selection options, see  VMware Multipathing policies in ESXi/ESX (1011340)

If a Connect to local host failed: Connection failure message is received, the hostd management agent process may not be running, which is required to use esxcli. In this situation, you can use localcli instead of esxcli.

For more information, see the 7.0 Command Line Reference Guide

vSphere Client HTML5 and Web Client

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

Select an ESXi host, and click in the Configure tab.

Click in Storage Devices.

Select a the storage device that you want to verify.

Scroll down in the Properties tab and click in "Edit multipathing...".

For information on multipathing options, see VMware Multipathing policies in ESXi/ESX (1011340).
