Esegui Hypercheck: strumento di verifica dello stato di Hyperflex e pre-aggiornamento
Sommario
Introduzione
Questo documento descrive il processo di esecuzione dello strumento Hypercheck Health and Pre-Upgrade.
Premesse
Questo strumento è un'utilità che esegue autocontrolli proattivi sui sistemi hyperflex per garantirne la stabilità e la resilienza. Consente di automatizzare un elenco di controlli dello stato e pre-aggiornamento dei sistemi Hyperflex per risparmiare tempo durante le operazioni di aggiornamento e manutenzione di Hyperflex.
Nota: scarica sempre la versione più recente dello strumento prima dell'uso. Poiché lo strumento viene migliorato frequentemente, l'utilizzo di una versione precedente può comportare la mancanza di controlli importanti.

- Versioni Hyperflex - 1.8, 2.0, 2.1, 2.5, 2.6, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5
- Cluster Hyperflex Standard
- Cluster Hyperflex Stretched
- Cluster Hyperflex Edge (2 nodi, 3 nodi e 4 nodi)
- Supportato solo su cluster Hyperflex su VMWare ESXi
Nota: per informazioni su come eseguire Hypercheck sul cluster HyperV hyperflex, visitare il sito https://www.cisco.com/c/en/us/support/docs/hyperconverged-infrastructure/hyperflex-hx-data-platform/216027-hypercheck-hyperflex-health-pre-upgr.html.

- Quando si lavora con Cisco TAC
- Controllo proattivo in qualsiasi momento
Modalità d'uso
HX versione 4.5 e successive
Passaggio 1. Avviare una connessione SSH alla macchina virtuale del controller di storage (SCVM) utilizzando l'IP di gestione del cluster (CMIP), che è l'IP della connessione HX.
Passaggio 2. Eseguire il comando hypercheck .
admin:~$ hypercheck
Passaggio 3. Quando richiesto, immettere la password SCVM admin e la password root di 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 versione 4.0 e precedenti
Passaggio 1. Scarica Hyperflex-Hypercheck.zip dall'account Cisco github devnet qui. Ottenere la copia più recente con gli ultimi miglioramenti e aggiornamenti.
Nota: utilizzare solo lo script scaricato dall'account devnet Cisco github.
Passaggio 2. Caricarlo nello SCVM con CMIP.
Utilizzare il metodo preferito: scp/sftp/ftp/tftp - Per copiare il Hyperflex-Hypercheck.zip alla /tmp directory.
Per MAC:
Eseguire SCP dalla CLI (verificare che il Hyperflex-Hypercheck.zip si trova nella stessa cartella da cui si esegue SCP).
# scp Hyperflex-Hypercheck.zip root@
Usare questo comando per identificare l'IP di gestione cluster nell'ambiente HX in uso - playbook Hyperflex.
Per Windows:
È possibile utilizzare WINSCP per trasferire i file come mostrato di seguito:
Passaggio 3. Estrarre il contenuto di Hyperflex-Hypercheck.zip.
Tipo cd /tmp al fine di passare alla /tmp directory.
root@SpringpathController7PVQWP6WV1:~# cd /tmp/
Tipo unzip Hyperflex-Hypercheck.zip per estrarre i file.
root@SpringpathController7PVQWP6WV1:/tmp# unzip Hyperflex-Hypercheck.zip
Archive: Hyperflex-Hypercheck.zip

Passaggio 4. Eseguire lo script HXTool Python.
Tipo cd Hyperflex-Hypercheck per passare al Hyperflex-Hypercheck directory.
root@SpringpathControllerABCDE01234:/tmp# cd Hyperflex-Hypercheck
Tipo python HXTool.py per eseguire lo script.
root@SpringpathControllerABCDE01234:/tmp/Hyperflex-Hypercheck# python HXTool.py
Passaggio 5. Quando richiesto, immettere la password della radice SCVM.
Enter this information of HX-Cluster:
Enter the HX-Cluster Root Password:
Enter the ESX Root Password:
Nota: per arrestare l'esecuzione dello script, utilizzare il tasto (CTRL+Z) e arrestarsi immediatamente.
Passaggio 6. Lo strumento Hyperflex-Hypercheck avvia i controlli. Il completamento dell'esecuzione, che dipende dal numero di nodi convergenti nel cluster, richiede circa 3-10 minuti.
Passaggio 7. Ottenere un report degli output dello script. È possibile ottenere quanto indicato di seguito:
OSPF (Open Shortest Path First) Hypercheck Report tar file salvato in /var/log/springpath e /tmp/Hyperflex-Hypercheck. Quindi, potete scaricare il pacchetto tar da sotto /var/log/springpath o /tmp/Hyperflex-Hypercheck. In alternativa, è possibile generare e caricare un bundle di supporto storfs che contiene anche l'hypercheck report tar.
Esempio di file TAR di report - HX_Report_2020_08_30_10_43_50.tar viene copiato nel percorso: /var/log/springpath.
Tipo ls -l | grep HX_Report per esaminare i file creati dallo strumento Hyperflex-Hypercheck.
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#
File e log nel bundle del log Hypercheck:
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
Passaggio 8. Esporta HX_YYYY_MM_DD_HH_MM_SS.tar e condividila con TAC.
Utilizzare il metodo preferito per esportare i log di Hypercheck con l'utilizzo di scp/sftp/ftp/tftp da SCVM o è possibile scaricare il pacchetto di supporto storfs che contiene il pacchetto tar HX_Report.

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.
Analisi output strumento - Passaggi successivi
- Lo strumento automatizza il processo di esecuzione dei comandi manuali su Hyperflex Systems.
- Se lo strumento esegue OK e passa a tutti i test, il sistema HX è adatto per tutti i controlli eseguiti dallo script.
- In situazioni in cui lo strumento
FAILSper alcuni controlli o se l'esecuzione non riesce, è possibile usare i comandi CLI (elencati) per eseguire sul sistema Hyperflex gli stessi controlli eseguiti manualmente dallo script. - Lo strumento non verifica eventuali avvertenze vecchie/nuove/aperte/risolte e pertanto si consiglia vivamente di esaminare
Hyperflex Release Notes and Upgrade Guidesprima di qualsiasi attività di aggiornamento o manutenzione.
Nota: non aprire una richiesta TAC perché l'esecuzione dello script non è riuscita. Eseguire i comandi manualmente, identificare il problema e aprire una SR per il problema identificato.
Comandi CLI
Su SCVM Hyperflex:
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)
Sui sistemi ESXi:
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
