  1. Kontrollér, om switchene er Arista på Gen 1 eller Gen 2 og Dell (eller en anden model) på Gen 3-miljøer.
BEMÆRK: Hvis switchene ikke er Arista- eller Dell-switche, er de brugeradministrerede switche. Vi skal underrette brugeren om, at de har en forbindelse, der skal afhjælpes.

  1. Kontroller konfigurationen af den offentlige grænseflade for binding af sekundær-0 og sekundær-1 for offentlig på noden, der ikke viser noget link, der er registreret fra kommandoen i trin 2:
Kommando: 
# sudo cat /etc/sysconfig/network/ifcfg-public
Eksempel:  
admin@node4:~> sudo cat /etc/sysconfig/network/ifcfg-public
BONDING_MASTER=yes
BONDING_MODULE_OPTS="miimon=100 mode=4 xmit_hash_policy=layer3+4"
BONDING_SLAVE0=slave-0
BONDING_SLAVE1=slave-1
BOOTPROTO=static
IPADDR=xxx.xxx.xxx.xxx/xx
MTU=1500
STARTMODE=auto
  1. Bekræft, at den korrekte LACP-parameter (Link aggregation Control Protocol) er indstillet på noderne. (IEEE 802.3ad Dynamic Link Aggregation er standardindstillingen og forventes.)

Kommando:

# viprexec -i "grep Mode /proc/net/bonding/public"

Eksempel:

admin@node1:~> viprexec -i "grep Mode /proc/net/bonding/public"

Output from host : 1xx.1xx.219.1
Bonding Mode: IEEE 802.3ad Dynamic link aggregation

Output from host : 1xx.1xx.219.2
Bonding Mode: IEEE 802.3ad Dynamic link aggregation

Output from host : 1xx.1xx.219.3
Bonding Mode: IEEE 802.3ad Dynamic link aggregation

Output from host : 1xx.1xx.219.4
Bonding Mode: IEEE 802.3ad Dynamic link aggregation
  1. Bekræft, at forbindelserne er konsistente med portene, og at grænsefladerne er tilsluttet, ved at køre følgende:
ECS Gen 1 eller Gen 2:      
Gen 1 eller Gen 2 ECS-tilknytninger for noderne er som følger til de tilsvarende switchporte:
Ethernet9 = node 1
Ethernet10 = node 2
Ethernet11 = node 3
Ethernet12 = node 4
Ethernet13 = node 5
Ethernet14 = node 6
Ethernet15 = node 7
Ethernet16 = node 8
 
Kommando:  
# viprexec -i "sudo lldpcli show neigh | egrep 'SysName|PortID'"
Eksempel: 
(Eksempel fra Gen 1 eller Gen 2 ECS) 
admin@ecssh121:~> viprexec -i "sudo lldpcli show neigh | egrep 'SysName|PortID'"                                                                                                                                                     
Output from host : 1xx.1xx.219.1
    SysName:      rabbit
    PortID:       ifname Ethernet9
    SysName:      hare
    PortID:       ifname Ethernet9
    SysName:      turtle
    PortID:       ifname Ethernet1

Output from host : 1xx.1xx.219.2
    SysName:      rabbit
    PortID:       ifname Ethernet10
    SysName:      hare
    PortID:       ifname Ethernet10
    SysName:      turtle
    PortID:       ifname Ethernet2

Output from host : 1xx.1xx.219.3
    SysName:      hare
    PortID:       ifname Ethernet11
    SysName:      rabbit
    PortID:       ifname Ethernet11
    SysName:      turtle
    PortID:       ifname Ethernet3

Output from host : 1xx.1xx.219.4
    SysName:      hare
    PortID:       ifname Ethernet12
    SysName:      turtle
    PortID:       ifname Ethernet4
 
BEMÆRK: I ovenstående eksempel mangler forbindelsen til Ethernet12-kanin for node 4. Med alle de oplysninger, der hidtil er indsamlet, ved vi nu, at port 12 er på kaninkontakten er forbundet til sekundær-0-grænsefladen i node 4.
 
ECS Gen 3:      
Gen 3 ECS-tilknytninger for noderne er som følger i forhold til de tilsvarende switchporte:
Ethernet1/1/1 = node 1 Ethernet1/1/2 = node 2
Ethernet1/1/3 = node 3
Ethernet1/1/4 = node 4
Ethernet1/1/5 = node 5
Ethernet1/1/6 = node 6
Ethernet1/1/7 = node 7
Ethernet1/1
/8 = node 8
  1. Bekræft, at forbindelserne er klar til ECS, der opretter forbindelse til de fire ECS Gen 3-switche, frontend, kanin og hare, backend, ræv og hund.

Kontroller, om der er mulige problemer med netværkskortet:
En anden komponent til at kontrollere, om nodes message buffer (dmesg) for de seneste NIC-problemer på den berørte node. I nedenstående eksempel skifter NIC mellem at være op og ned status.

Hvis der er en NIC-advarsel i dmesg, skal den muligvis udskiftes.

  • Hvis ECS Gen 1 eller Gen 2 - Giv output til ECS support hardware ingeniør til analyse.
  • Hvis ECS Gen 3 – Levere output til Dells hardwareteam, som ville være ekspert i EX-seriens hardware.

 

Kommando:

# sudo dmesg -T

Cause

Mulige årsager til dette problem:
  • Nogle gange sad SFP'en (lille formfaktor, som kan tilsluttes) ikke korrekt i installationsfasen. 
  • Brugeradministrerede switche, der udføres med ændringer, der ligger uden for vores kontrol (I tilfælde, hvor brugeradministrerede switche vedligeholdes, f.eks. firmwareopgraderinger, kan et link gå ned og sandsynligvis blive genforhandlet som vist i løsningsdelen nedenfor.)
  • Defekt hardware på ECS:
    • Netværkskort
    • Netværkskabel 
    • SFP (lille formfaktor, som kan tilsluttes) 
    • Netværksswitch eller -switchport

Resolution

Før du udfører noget arbejde
I tilfælde, hvor brugeradministrerede switche vedligeholdes, f.eks. firmwareopgraderinger, kan et link gå ned og sandsynligvis blive genforhandlet. Eksemplet nedenfor er for sekundær-0 ned efter en firmwareopgradering udført af brugeren på en brugeradministreret FE-switch. Nedenstående kommando bruges til genforhandling af grænsefladen:

BEMÆRK: Hvis grænsefladen stadig er nede og ikke kan genforhandles, skal en Dell-repræsentant være på stedet for at inspicere og genindsætte SPF og kablet. Hvis dette ikke virker, anbefales det at udskifte SFP- og kabelforbindelsen fra kontakten til noden.

Der er forskellige SFP-modeller, der bruger enten kobber eller fiber. Backend- og frontend-switche kan også bruge forskellige typer SFP-ledninger. Bekræft, hvilken del der kræves, før du udskifter delen.

Uddrag fra ECS-hardwarevejledning Gen1 eller Gen2:      

Netværkskabler
Netværkskabeldiagrammerne gælder for ECS-enheder i U-serien, D-serien eller C-serien i et Dell- eller kundeleveret rack.
 
For at skelne mellem de tre switche har hver switch et kaldenavn:
  • Hare: 10 GbE offentlig switch er øverst på racket i en U- eller D-serie eller den øverste switch i et C-seriesegment.
  • Kanin: 10 GbE offentlig switch er placeret under haren i toppen af racket i en U- eller D-serie eller under harekontakten i et segment i C-serien.
  • Skildpadde: 1 GbE privat switch, der er placeret under kanin i toppen af racket i en U-serie eller under harekontakten i et C-seriesegment.
Netværkskabler
i U- og D-serienFølgende figur viser et forenklet netværkskabeldiagram for en rackkonfiguration med otte noder til en ECS i U- eller D-serien, der er konfigureret af Dell eller kunden. Efter denne figur indeholder andre detaljerede figurer og tabeller oplysninger om port, etiket og kabelfarve.
 
Forenklet netværkskabeldiagram for en rackkonfiguration med otte noder
Se nedenstående tabel for matchende switche og porte og tallet for også at vise de relevante switchportnumre.

Switch 1 = Kanin = Bundkontakt
Switch 2 = Hare = Top switch

Nodeporte:      
Sekundær-0 = P01 = højre port - forbinder til Switch 1 / Rabbit / Bottom switch.
Sekundær-1 = P02 = venstre port - forbinder til Switch 2 / Hare / Top switch.
