Symptoms

NetWorker VMware Protection-integrasjonen er konfigurert med vProxy Appliance. Informasjonen i emcauthctomcat kan fjernes når Java Runtime Environment (JRE)-installasjonen oppgraderes på NetWorker-serveren. vSphere Web Client-pluginmodulen kan ikke koble til NetWorker-serveren med følgende feil:
 

Feil: Kan ikke koble til den forespurte feilmeldingen for NetWorker Server 
Figur 1: Kunne ikke koble til den forespurte NetWorker-serveren.

Cause

JRE-installasjonen har ikke lenger NetWorker Tomcat-godkjenning (emcauthctomcat) sertifikat som brukes av vSphere Web Client VM Backup and Recovery plug-in. 

Resolution

Emcauthctomcat-sertifikatet må importeres til Java JRE-nøkkellagerkonfigurasjonen. Her er en oversikt for å sjekke om sertifikatet finnes og for å importere sertifikatet.

  1. Åpne en Windows-ledetekst eller Linux-terminaløkt på NetWorker-serveren.
  2. Bytt til Java JRE-installasjonskatalogen. Katalogen endres avhengig av den installerte Java JRE-versjonen.  
Eksempel på installasjonsbaner for JRE 1.8.0_151
  • Windows: C:\Program Files\Java\jre1.8.0_151\bin>
  • Linux: /usr/java/jre1.8.0_151/bin
Eksempel på installasjon av NetWorker Runtime Environment (NRE):
  • Windows: C:\Program Files\NRE\java\jre#.#.#_###\bin
  • Linux: /opt/nre/java/latest/bin
  1. Bruk kommandolinjeverktøyet keytool til å validere om sertifikatet ikke finnes i Java JRE cacerts-nøkkellageret:
    • Windows:
keytool -list -storepass changeit -keystore ..\lib\security\cacerts | findstr emc
  • Linux:
keytool -storepass changeit -list  keystore ../lib/security/cacerts | grep emc
  1. Bruk kommandolinjeverktøyet for nøkkelverktøy til å importere emcauthctomcat sertifikat:
    • Windows:
keytool -importcert -storepass changeit -trustcacerts -alias emcauthctomcat -file "C:\Program Files\EMC NetWorker\nsr\authc-server\tomcat\conf\emcauthctomcat.cer"  -keystore ..\lib\security\cacerts
  • Linux:
keytool -importcert -storepass changeit -trustcacerts -alias emcauthctomcat -file /nsr/authc/conf/emcauthctomcat.cer -keystore ../lib/security/cacerts 
  1. Bruk kommandolinjeverktøyet keytool til å validere om sertifikatet nå finnes i Java JRE cacerts-nøkkellageret:
    • Windows:
keytool -list -storepass changeit -keystore ..\lib\security\cacerts | findstr emc
  • Linux:
keytool -storepass changeit -list  keystore ../lib/security/cacerts  | grep emc
