vProxy 백업 실패, 오류: ddp_connect_with_config() 실패, 호스트 이름: DD_name, 오류: 5075-DD_Name에서 /backup/ost 조회에 대한 DDBOOST 오류 1

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

초기 점검:

• DDBoost가 DD에서 실행 중입니다.
• Data Domain에서 NFSv3가 활성화되어 있음
• DD와 vProxy 사이에 방화벽 포트가 열려 있습니다. NVP vProxy: 백업 및 복원 작업을 위한 네트워크 연결 문제 해결
• 사용된 DDBoost 암호가 올바릅니다.
• DDBoost 클라이언트 구성은 다음과 같은 특정 클라이언트를 허용합니다.

• 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
  
  
  
  

위의 내용이 모두 확인되면 vProxy에 사용 중인 MTREE의 DDBoost 암호 길이를 확인합니다. vProxy와 함께 사용할 수 있는 최대 암호는 30자입니다.

암호 길이가 과도하지 않은 경우 'ddpconnchk' 유틸리티를 사용하여 vProxy와 DD 간의 접속 구성을 확인하는 것이 좋습니다. ' 사용에 대한 자세한 내용ddpconnchk': NetWorker: DDPCONNCHK 툴을 사용하여 NetWorker 호스트에서 DD ddboost 접속을 테스트하는 방법
