Configure Hyperflex Auto Support

Introduction

This document describes the automatic support and Smart Call Home for Cisco Hyperflex systems.

You can configure the HX storage cluster to send automated email notifications regarding documented events. The data collected in the notifications can be used to help troubleshoot issues in your HX storage cluster.

Prerequisites

Requirements

Cisco recommends that you have knowledge of these topics:

• HXDP Cluster
• SMTP Server
• HX Connect

Components Used

The information in this document is based on these software and hardware versions:

• HX Cluster version 3.0(1c)
• SMTP Email Server DNS

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Configuration

Configure via HX Connect UI

Step 1. Login to HX connect. Click on Edit settings (gear icon) and choose Auto Support Settings, as shown in the image.

Step 2. Click on Auto Support Setting and configure the parameters.

Note: If you Enable Remote Support - It enables access to your HX storage cluster by Support to collect information about cluster operations to accelerate troubleshooting on reported anomalies.

Step 3. In the banner, click Edit settings (gear icon) and then check the Notifications Settings.

Configure via CLI

Step 1. Enable ASUP notification.

# stcli services asup enable

Step 2. Configure the SMTP mail server.

# stcli services smtp set --smtp mailhost.eng.mycompany.com --fromaddress smtpnotice@mycompany.com

Step 3. Add recipient email address.

# stcli services asup recipients add --recipients user1@mycompany.com user2@mycompany.com

Verify

Step 1. Login to SCVM Cluster IP and run this command from CLI.

Step 2. Run the command sendasup -t from SCVM, confirm that you do not see any "failure message" for the ASUP email.

Step 3. Check and confirm you receive the email with ASUP test email which contains information about cluster state.

Troubleshoot

Step 1. Check the configuration in the asup.cfg file. Sample file.

Step 2. If you do not see the test email is received or if you see a failure when the test is performed, perform a tcpdump simultaneously to see why it might be failing,

Example tcpdump - SMTP port number is 25, so run  #tcpdump -v "port 25"

Sample Email Output from Working SMTP tcp connection.

root@SpringpathController:~# tcpdump -v "port 25"
