Symptoms

Avamar SQL-sikkerhedskopiering af AlwaysON-klynge med dobbelt hus mislykkes.

Fra avsql-tilføjelsesprogrammets primære logfil:

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 AlwaysON SQL-klyngemiljø med to huse fortolkes SQL-noderne med fuldt kvalificeret domænenavn (FQDN) til IP-adressen fra produktionsnetværket. Dette netværk har ikke adgang til sikkerhedskopieringsnetværket.

 

Dette problem kan ses i miljøer med flere netværkskort, eller hvor der er forskellige vLAN er involveret.

 

Resolution

Permanent afhjælpning:
Opgrader Avamar Server til.

  • 19.7.100-82 eller nyere
  • Rettelsen er inkorporeret i Avamar 19.7 og nyere softwareudgivelser.
    • Nyt flag i avsql.cmd-filen i den delte AlwaysON-VAR: 
      • --clusternode=<SQL_node_name>(<IP_ADDRESS>)
