PDF
Seguire questa procedura per installare lo script RCF.
Di cosa hai bisogno
Prima di installare lo script RCF, assicurarsi che sullo switch siano disponibili le seguenti informazioni:
-
Cumulus Linux è installato. Vedere "Hardware Universe" per le versioni supportate.
-
Indirizzo IP, subnet mask e gateway predefinito definiti tramite DHCP o configurati manualmente.
|
È necessario specificare un utente nell'RCF (oltre all'utente amministratore) da utilizzare specificamente per la raccolta dei log. |
Versioni correnti degli script RCF
Sono disponibili due script RCF per le applicazioni cluster e storage. Scaricare gli RCF da "qui". La procedura per ciascuno di essi è la stessa.
-
Cluster: MSN2100-RCF-v1.x-Cluster-ha-Breakout-LLDP
-
Storage: MSN2100-RCF-v1.x-Storage
A proposito degli esempi
La seguente procedura di esempio mostra come scaricare e applicare lo script RCF per gli switch del cluster.
L'output di comando di esempio utilizza l'indirizzo IP di gestione dello switch 10.233.204.71, la netmask 255.255.254.0 e il gateway predefinito 10.233.204.1.
Esempio 1. Fasi

Copiare lo script python RCF sullo switch.
cumulus@cumulus:mgmt:~$ cd /tmp cumulus@cumulus:mgmt:/tmp$ scp <user>@<host:/<path>/MSN2100-RCF-v1.x-Cluster-HA-Breakout-LLDP . ssologin@10.233.204.71's password: MSN2100-RCF-v1.x-Cluster-HA-Breakout-LLDP 100% 8607 111.2KB/s 00:00
Mentre scpviene utilizzato nell'esempio, è possibile utilizzare il metodo di trasferimento file preferito. -
Applicare lo script python RCF MSN2100-RCF-v1.x-Cluster-ha-Breakout-LLDP.
cumulus@cumulus:mgmt:/tmp$ sudo python3 MSN2100-RCF-v1.x-Cluster-HA-Breakout-LLDP [sudo] password for cumulus: ... Step 1: Creating the banner file Step 2: Registering banner message Step 3: Updating the MOTD file Step 4: Ensuring passwordless use of cl-support command by admin Step 5: Disabling apt-get Step 6: Creating the interfaces Step 7: Adding the interface config Step 8: Disabling cdp Step 9: Adding the lldp config Step 10: Adding the RoCE base config Step 11: Modifying RoCE Config Step 12: Configure SNMP Step 13: Reboot the switch
Lo script RCF completa le istruzioni elencate nell'esempio precedente.
Nel passaggio 3 aggiornamento del file MOTD precedente, il comando cat /etc/motdè eseguito. Questo consente di verificare il nome file RCF, la versione RCF, le porte da utilizzare e altre informazioni importanti nel banner RCF.
Per qualsiasi problema di script RCF python che non può essere corretto, contatta "Supporto NetApp" per assistenza. -
Riapplicare le eventuali personalizzazioni precedenti alla configurazione dello switch. Fare riferimento a "Esaminare le considerazioni relative al cablaggio e alla configurazione" per i dettagli su eventuali ulteriori modifiche necessarie.
