Installare lo script RCF

Collaboratori
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 4.4.3 è installato.

  • Indirizzo IP, subnet mask e gateway predefinito definiti tramite DHCP o configurati manualmente.

Versioni correnti degli script RCF

Sono disponibili due script RCF per le applicazioni di clustering e storage. La procedura per ciascuno di essi è la stessa.

  • Clustering: MSN2100-RCF-v1.8-Cluster

  • Storage: MSN2100-RCF-v1.8-Storage

Nota La seguente procedura di esempio mostra come scaricare e applicare lo script RCF per gli switch del cluster.
Nota 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.
Fasi

  1. Visualizzare le interfacce disponibili sullo switch SN2100:

    net show interface all

    Mostra esempio 
    cumulus@cumulus:mgmt:~$ net show interface all

State  Name   Spd  MTU    Mode         LLDP                Summary

  2. Copiare lo script python RCF sullo switch:

    cumulus@cumulus:mgmt:~$ pwd
/home/cumulus
cumulus@cumulus:mgmt: /tmp$ scp <user>@<host:/<path>/MSN2100-RCF-v1.8-Cluster
ssologin@10.233.204.71's password:
MSN2100-RCF-v1.8-Cluster                 100% 8607   111.2KB/s         00:00

  3. Applicare lo script python RCF MSN2100-RCF-v1.8-Cluster:

    cumulus@cumulus:mgmt:/tmp$ sudo python3 MSN2100-RCF-v1.8-Cluster
[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 sopra.

    Nota Per qualsiasi problema di script RCF python che non può essere corretto, contatta "Supporto NetApp" per assistenza.

  4. Verificare la configurazione dopo il riavvio:

    net show interface all

    Mostra esempio 
    cumulus@cumulus:mgmt:~$ net show interface all

  5. Verificare le informazioni relative al ricetrasmettitore nell'interfaccia:

    net show interface pluggables

    Mostra esempio 
    cumulus@cumulus:mgmt:~$ net show interface pluggables
Interface  Identifier     Vendor Name  Vendor PN        Vendor SN       Vendor Rev

swp16      0x11 (QSFP28)  Amphenol     112-00573        APF21109347895  B0

  6. Verificare che i nodi dispongano di una connessione a ciascuno switch:

    net show lldp

    Mostra esempio 
    cumulus@cumulus:mgmt:~$ net show lldp

LocalPort  Speed  Mode        RemoteHost              RemotePort
---------  -----  ----------  ----------------------  -----------
swp3       100G   Trunk/L2    sw1                     e3a

swp16      100G   BondMember  sw14                    swp16

  7. Verificare lo stato delle porte del cluster sul cluster.

    1. Verificare che le porte e0d siano in buone condizioni su tutti i nodi del cluster:

      network port show -role cluster

    Mostra esempio 
    cluster1::*> network port show -role cluster

Node: node1
                                                                       Ignore

Node: node2
                                                                       Ignore
                                                  Speed(Mbps) Health   Health

e3b       Cluster      Cluster          up   9000  auto/10000 healthy  false

    1. Verificare lo stato dello switch dal cluster (potrebbe non essere visualizzato lo switch sw2, poiché i LIF non sono presenti su e0d).

      Mostra esempio 
      cluster1::*> network device-discovery show -protocol lldp
Node/       Local  Discovered
Protocol    Port   Device (LLDP: ChassisID)  Interface Platform

            e3b    sw2 (b8:ce:f6:19:1b:96)   swp3      -

node2/lldp
            e3a    sw1 (b8:ce:f6:19:1a:7e)   swp4      -
            e3b    sw2 (b8:ce:f6:19:1b:96)   swp4      -


cluster1::*> system switch ethernet show -is-monitoring-enabled-operational true
