Symptoms

vProxy-back-up mislukt met fout:
ddp_connect_with_config() failed, Hostname: DD_name, Err: 5075-DDBOOST Error 1 for lookup /backup/ost on DD_Name (nfs: Operation not permitted)

Cause

Eerste controle:

  • DDBoost wordt uitgevoerd op de DD
  • NFSv3 is ingeschakeld op het Data Domain
  • Firewallpoorten zijn open tussen de DD en vProxy: NVP vProxy: Problemen met netwerkconnectiviteit oplossen voor back-up- en herstelbewerkingen
  • DDBoost gebruikt wachtwoord is correct
  • Met DDBoost-clientconfiguratie kan deze specifieke client:
  • 1) Example:  
    
    Below example shows both "*" and a client name.  If "*" is missing then only clients in the list are permitted to connect to the DD.
    
    # ddboost clients show config
    Client               Encryption Strength   Authentication Mode
    ------------------- -------------------   -------------------
    *                    none                  none
    MyClient.mycomp.com  none                  none
    MyOtherClient        none                  none
    -------------------  -------------------   -------------------
    (**) The global security settings take precedence over these client(s) specific settings.
    
    2) Example from ddfs.info:
    07/03 14:59:25.659490 [7ff122a44170] WARNING: Client <MyOtherClient.mycomp.com> did not match access list entries
    07/03 14:59:25.659521 [7ff122a44170] nfsproc3_ost_mnt_3_svc: client access denied for <Client IP> version 7.0
    
    3) In some cases you will see that the error log lists the FQDN or the short name, but the client config is using the other form of the name. The configuration and the client name must match exactly. The DDBoost Plugin on the client will determine the name for the client. This will check the local hosts file on the client for a match for the source side IP for the client. If there is a match, it will use it. (Selecting the FQDN name if one is available, then short name) If there is no match, then the plugin will do a DNS query for the IP and use the response returned.
    
    4) If there is a discrepancy between the clients local host entry verses the DDBoost client config, ask the customer to choose which configuration that they would like to change.
    
    a) add "*" to the DD clients list will allow any client with proper credentials to authenticate to the DD.
    # ddboost clients add *
    
    b) add the corresponding name (from the error log, or client side local hosts file) to the DD:
    # ddboost clients add <hostname>
    
    c) modify the local hosts file or DNS for the IP address being used by the client to make it reflect the client name that was added to DD clients list.
    Example for Linux:
    file: /etc/hosts
    10.11.12.13 MyOtherClient.mycomp.com MyOtherClient
      changed to 
    10.11.12.13 MyOtherClient
    
    
    
    

Resolution

Als al het bovenstaande is bevestigd, controleer dan de lengte van het DDBoost-wachtwoord voor de MTREE die wordt gebruikt voor vProxy. Het maximaal toegestane wachtwoord voor gebruik met vProxy is 30 tekens lang.

Als de wachtwoordlengte niet te lang is, wordt een verbindingscontrole tussen de vProxy en DD aanbevolen met behulp van het hulpprogramma 'ddpconnchk'.
