Herstel MDS 9000 opstartlader-prompt
Inleiding
In dit document wordt beschreven hoe u een meerlaagse Datacenter Switch (MDS) kunt herstellen van de Boot Loader Prompt en Boot Mode.
Voorwaarden
Vereisten
Cisco raadt u aan kennis te hebben van deze onderwerpen:
- MDS 9000 CLI-configuratieopdrachten
- Hoe een consoleverbinding met MDS switch op te zetten.
- MDS-switch instellen of aansluiten op een netwerk via de beheerpoort.
- Bekendheid met TFTP.
Gebruikte componenten
De informatie in dit document is gebaseerd op softwarevereiste release 6.2(9) en hoger. Dit document maakt gebruik van een MDS9148S switch, switchname tempest die 12 tot 48 16 Gbps Fibre Channel-poorten met lijnsnelheid ondersteunt.
De informatie in dit document is gebaseerd op de apparaten in een specifieke laboratoriumomgeving. Alle apparaten die in dit document worden beschreven, hadden een opgeschoonde (standaard)configuratie. Als uw netwerk live is, moet u zorgen dat u de potentiële impact van elke opdracht begrijpt.
Achtergrondinformatie
Om goed te kunnen functioneren, hebben MDS-switches een geldig, niet-beschadigd Kickstart- en systeembeeld nodig om volledig op te starten. Ongeldige, beschadigde of ontbrekende Kickstart-afbeeldingen voorkomen dat een switch opstart en stopt bij de Boot Loader Prompt. Een switch met een geldig Kickstart-beeld, maar een ongeldig of ontbrekend systeembeeld, belandt in de opstartmodus.
Switch Boot Up-reeks
BIOS > Loader > Kickstart Image > System Image
- Het Basic Input Output System (BIOS) laadt de lader.
- De Loader laadt de Kickstart Image in RAM en start de Kickstart Image.
- Het Kickstart-beeld wordt geladen en de systeemafbeelding wordt gestart.
- De systeemafbeelding leest het opstartconfiguratiebestand.

Stap 1. Download de Kickstart- en systeemafbeeldingen van de switch en zet ze in de TFTP-servermap.
In dit voorbeeld is IP-adres van TFTP-server 10.104.204.100.
Stap 2. Configureer het IP-adres, het subnetmasker en de standaardgateway van het switch beheer.
Check config options in loader prompt using help option
loader> help
help - print online help
boot - Boot image
cmdline - <arguments>
dir - List Directory
help - print online help
network - Set network communication settings
reload - Reboot the board.
serial - Set serial console settings
show - Show loader configuration
loader> net --ip=10.66.78.80 --nm=255.255.255.128 --gw=10.66.78.4
In dit voorbeeld:
- Het switch interface mgmt0 IP-adres is 10.66.78.80 255.255.255.128
- Het switch standaard gateway IP adres is 10.6.78.4
OF
De IP-toewijzingssyntaxis in de loader-prompt varieert enigszins voor switch-HW-modellen.
Voorbeeld hier vermeld in het geval van T&V-Series Fabric switches.
loader> set ip 10.66.78.80 255.255.255.128
loader> set gw 10.66.78.4
Opmerking: Stap 2 configuratie vereist als u de switch voor het eerst opstart (voor de RMA switch) of de switch is schrijfwisser start.
Stap 3. Start het Kickstart-beeld dat zich in de TFTP-servermap bevindt om de switch naar de opstartmodus te brengen.

Stap 4. Herstel de switch van de laarswijze.
1. Controleer IP-configuratie in de opstartmelding voor de switch.
switch(boot)# sh ip
ip routing is disabled
Management Interface: ip address 10.66.78.80/25
ip default-gateway 10.66.78.4
Als IP Config niet wordt gevonden, configureer dan het IP-adres van het interfacebeheer en het IP-adres van de standaardgateway opnieuw zoals aangegeven op de afbeelding.
switch(boot)# config t Enter configuration commands, one per line. End with CNTL/Z. switch(boot)(config)# interface mgmt 0 switch(boot)(config-if)# ip address 10.66.78.80 255.255.255.128 switch(boot)(config-if)# no shut switch(boot)(config-if)# exit switch(boot)(config)# ip default-gateway 10.66.78.4 switch(boot)(config)# exit
