Run Hypercheck: Hyperflex Health and Pre-Upgrade Check Tool

Introduction

This document describes the process to run the Hypercheck Health and Pre-Upgrade tool.

Background Information

This tool is a utility that performs proactive self-checks on hyperflex systems in order to ensure their stability and resiliency. It helps automate a list of health and pre-upgrade checks on the Hyperflex systems in order to save time during Hyperflex upgrade and maintenance operations.

Note: Always download the latest version of the tool before use. Since the tool is enhanced frequently, the use of an earlier version can result in missing important checks.

Supported HX Systems

• Hyperflex Versions - 1.8, 2.0, 2.1, 2.5, 2.6, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5
• Hyperflex Standard Cluster
• Hyperflex Stretched Cluster
• Hyperflex Edge Cluster (2 Node, 3 Node, and 4 Node)
• Only supported on Hyperflex cluster on VMWare ESXi

Note: For information on how to run Hypercheck on the hyperflex HyperV cluster, visit https://www.cisco.com/c/en/us/support/docs/hyperconverged-infrastructure/hyperflex-hx-data-platform/216027-hypercheck-hyperflex-health-pre-upgr.html.

When to Use

• Before Hyperflex upgrades
• Hyperflex health check before and after maintenance windows
• In order to identify failed drives/disks
• When you work with Cisco TAC
• Pro-active health check anytime

How to Use

HX Version 4.5 and Later

Step 1. Initiate an SSH connection to the Storage Controller VM (SCVM) using the Cluster Management IP (CMIP), which is your HX-connect IP.

Step 2. Execute the command  hypercheck .

admin:~$ hypercheck

Step 3. Enter the SCVM admin password when prompted and enter the root password of the ESXi.

admin:~$ hypercheck

                  HX Health Check 4.5.0

Please enter below info of HX-Cluster:
Enter the HX-Cluster Root Password:
Enter the HX-Cluster Admin Password:
Enter the ESX Root Password:

HX Version 4.0 and Earlier

Step 1. Download  Hyperflex-Hypercheck.zip from the Cisco github devnet account here. Get the most recent copy which has the latest improvements and updates.

Note: Use only the script downloaded from the Cisco github devnet account.

Step 2. Upload It to the SCVM with the CMIP.

Use your preferred method - scp/sftp/ftp/tftp - In order to copy the  Hyperflex-Hypercheck.zip to the  /tmp directory.

For MAC:

Perform SCP from CLI (confirm that the  Hyperflex-Hypercheck.zip is in the same folder from where you run SCP).

# scp Hyperflex-Hypercheck.zip root@<scvm-eth0:mgmtip>:/tmp/.

Use this in order to identify the Cluster Management IP in your HX environment - Hyperflex playbook.

For Windows:

You can use WINSCP in order to transfer the files as shown here:

Step 3. Extract the contents of  Hyperflex-Hypercheck.zip.

Type  cd /tmp in order to change to the  /tmp directory.

root@SpringpathController7PVQWP6WV1:~# cd /tmp/

Type  unzip Hyperflex-Hypercheck.zip in order to extract the files.

root@SpringpathController7PVQWP6WV1:/tmp# unzip Hyperflex-Hypercheck.zip 
Archive:  Hyperflex-Hypercheck.zip

Step 4. Execute the HXTool Python script.

Type  cd Hyperflex-Hypercheck in order to navigate to the  Hyperflex-Hypercheck directory.

root@SpringpathControllerABCDE01234:/tmp# cd Hyperflex-Hypercheck

Type  python HXTool.py  in order to execute the script.

root@SpringpathControllerABCDE01234:/tmp/Hyperflex-Hypercheck# python HXTool.py

Step 5. Enter the SCVM root password when prompted.

Enter this information of HX-Cluster:
Enter the HX-Cluster Root Password:
Enter the ESX Root Password:

Note: In order to stop the script execution use the key (CTRL+Z) and it stops immediately.

Step 6. Hyperflex-Hypercheck tool starts its checks. It takes about 3-10 minutes for the execution to complete which depends on the number of converged nodes in the cluster.

Step 7. Get a report of the script outputs. You can get it as shown:

The Hypercheck Report tar file is saved under  /var/log/springpath  and  /tmp/Hyperflex-Hypercheck. So, you can download the tar bundle from under  /var/log/springpath or  /tmp/Hyperflex-Hypercheck. Alternatively, you can just generate and upload a storfs-support bundle which also contains the hypercheck report tar.

Report tar file example -  HX_Report_2020_08_30_10_43_50.tar is copied to path:  /var/log/springpath.

Type  ls -l | grep HX_Report in order to review the files created by the Hyperflex-Hypercheck tool.

Under /var/log/springpath,

root@SpringpathControllerABCDE01234:/var/log/springpath# ls -l | grep HX_Report
-rw-r--r-- 1 root root 380K Sep 23 15:41 HX_Report_2020_08_30_10_43_50.tar
root@SpringpathControllerABCDE01234:/var/log/springpath#

Under /tmp/Hyperflex-Hypercheck,

root@SpringpathControllerABCDE01234:/tmp/Hyperflex-Hypercheck# ls
HX_Report_2020_08_30_10_43_50.tar prettytable.py HX_Report_2020_08_30_10_43_50 TestInfo.txt progressbar.py
HXTool.py prettytable.pyc ReadMe.txt progressbar.pyc LICENSE.txt
root@SpringpathControllerABCDE01234:/tmp/Hyperflex-Hypercheck# 

Files and logs in the Hypercheck log bundle:

root@SpringpathControllerABCDE01234:/tmp/Hyperflex-Hypercheck# ls HX_Report_2020_08_30_10_43_50/
HX_Tool_2020-08-30_10-43-50.log 
HX_Tool_Main_Report_2020-08-30_10-54-34.txt 
HX_Tool_Summary.json

Step 8. Export the  HX_YYYY_MM_DD_HH_MM_SS.tar and share it with TAC.

Use your preferred method in order to export the Hypercheck logs with the use of  scp/sftp/ftp/tftp from the SCVM or you can simply download the storfs-support bundle which contains the HX_Report tar bundle.

Upgrade Guides:
https://www.cisco.com/c/en/us/support/hyperconverged-systems/hyperflex-hx-data-platform-software/products-installation-guides-list.html

Note:
1) If upgrading to HX 4.0(2a), please review the following link and perform workaround – https://tinyurl.com/wc7j5qp
2) Please check the status of Compute nodes manually, script only verifies the config on the converged nodes.
3) Hypercheck doesnot perform FAILOVER TEST, so please ensure that the upstream is configured for network connectivity for JUMBO or NORMAL MTU size as needed.
4) If you have performed any activity on your vcenter(like upgrade, certificate replacement,etc.), it is recommended to reregister your cluster to the vcenter before performing upgrades. Refer to the Hyperflex CLI guide for relevant commands. 

Analyze Tool Output - Next Steps

• The tool automates the process of running manual commands on Hyperflex Systems.
• If the tool runs  OK  and gives a  PASS  on all tests, the HX system is good for all the checks that the script has performed.
• In situations where the tool  FAILS  on some checks or does not run successfully, you can use the CLI commands (that are listed) in order to perform the same checks on Hyperflex System as done by the script manually.
• The tool does not check for any old/new/open/resolved caveats and hence it is highly recommended to review the  Hyperflex Release Notes and Upgrade Guides  before any upgrade or maintenance activity.

Note: Do not open a TAC case because the script failed to run. Run the commands manually, identify the issue, and open an SR for the problem identified.

CLI Commands

On Hyperflex SCVM:

SSH to All Hyperflex SCVMs-

# service_status.sh

# sysmtool --ns cluster --cmd enospcinfo

# echo srvr | nc 0 2181

# pidof exhibitor

# stcli disk list --ip <Corresponding ESXi Mgmt IP Address> |grep -B 2 -A 8 blacklisted

# stcli services dns show (and ping the IPs listed)

# ping <vCenter IP Address>

# date ; compare the time on all SCVMs. They should ideally be identical

# stcli services ntp show

# stcli cleaner info

# ntpq -p -4 

# dpkg -l | grep -i springpath | grep -v storfs-support*

# sysmtool --ns disk --cmd list | grep -i blacklisted

# iptables -L -n | wc -l 

# stcli cluster info

# df -h ; check that /var/stv should be less than 80%

# zgrep -i “out of memory” /var/log/springpath/debug-storfs.*

# ping -I eth0 <eth0> of all SCVMs

# ping -I eth1 <eth1> of all SCVMs

# "ls -ld /tmp" check for 775 and 777

# stcli cluster info | grep -i 'clusterAccessPolicy:' | head -1

# md5sum /etc/springpath/secure/springpath_keystore.jceks

# cat /etc/springpath/sed_capability.conf

# cat /etc/springpath/sed.conf

# cat /var/log/springpath/diskslotmap-v2.txt

# stcli cluster info | grep dataZkIp (ping dataZkIp for latency)

On ESXi Systems:

SSH to all ESXi hosts

# esxcli system account list

# esxcli network firewall ruleset list | grep -i vMotion

# esxcli software vib list| egrep -i 'scvm|stHyper|stfs'

# chkconfig --list | grep -E 'ntpd|hostd|vpxa|stHypervisorSvc|scvmclient|hxctlvm' 

# esxcfg-vmknic -l ; confirm that vMotion VMK2 is created

# vmkping -I vmk1 <eth1> of all SCVMs

# cd /vmfs/volumes/Springpath-XXXXXXXXXX ; Ensure that it has only one Folder that has the Storage Controller VM

# df -h | grep vfat  ; Ensure dir has free space
