Symptoms

Avamar SQL-sikkerhetskopiering av dual-homed AlwaysON-klynge mislykkes.

Fra hovedloggen for avsql-plugin-modulen:

2017/01/26-11:46:01.41899 [avsql_assist]  avsql_iac_manager::forward_ctl_message() received response dequeued_ret    on queue remote
2017-01-26 12:46:01 avsql Error <0000>: Unable to connect to the remote client '10.x.x.22', error code: 2.
Please ensure that the remote backup agent is running.
2017/01/26-11:46:01.41899 [avsql_assist]  <=== avsql_iac_manager::forward_ctl_message
2017-01-26 12:46:01 avsql Error <12758>: [<Cluster-Client-name>] is unable to forward CTL sub-workorder to [<SQL-SRV-name\instance-name>].
2017/01/26-11:46:01.41899 [avsql_assist]  ===> avsql_iac_manager::update_client_status
2017-01-26 12:46:01 avsql Info <17370>: Remote client: <SQL-SRV-name\instance-name> (10.x.x.22), Status: FAILED
From remote client avagent log we don't see any sub-workorder as the IP in question (10.x.x.22) cannot be contacted from backup IP of AlwaysON listener (10.x.x.81):
initiator_agent_ip="10.x.x.81"
remote_agent_ip="10.x.x.22"

 

Cause

For dual-homed AlwaysON SQL-klyngemiljø løses SQL-nodenes fullstendige kvalifiserte domenenavn (FQDN) til IP-adressen fra produksjonsnettverket. Dette nettverket har ikke tilgang til sikkerhetskopieringsnettverket.

 

Dette problemet kan oppstå i miljøer med flere NIC-er, eller der forskjellige vLAN-er er involvert.

 

Resolution

Permanent løsning:
Oppgrader Avamar Server til.

  • 19.7.100-82 eller nyere
  • Hurtigreparasjonen er inkludert i Avamar 19.7 og nyere programvareversjoner.
    • Nytt flagg i avsql.cmd-filen i AlwaysON-delte VAR: 
      • --clusternode=<SQL_node_name>(<IP_ADDRESS>)
