NetWorker: Como usar nsr_render_log

 

  • O comando netstat no client tem CLOSE_WAIT para 7937 e 7938.
root@<Client_Name> # netstat -an | grep -i 7938
<ip_address_1>.37938 <ip_address_1>.9151 49878 0 49152 0 CLOSE_WAIT
<ip_address_1>.47938 <ip_address_1>.9151 49877 0 49152 0 CLOSE_WAIT
<ip_address_1>.57938 <ip_address_1>.9151 49877 0 49152 0 CLOSE_WAIT
 
root@fmsprochk1 # netstat -an | grep -i 7937
<ip_address_1>.37937 <ip_address_1>.9151 49875 0 49152 0 CLOSE_WAIT
<ip_address_1>.57937 <ip_address_1>.9151 49878 0 49152 0 CLOSE_WAIT
<ip_address_1>.47937 <ip_address_1>.9151 49878 0 49152 0 CLOSE_WAIT

 

  • O arquivo /etc/hosts no client tem:
::1 localhost
127.0.0.1 localhost localhost.localdomain

 

  • Confirmado com ipfstat -io Que o firewall (filtro de IP) não está em execução nem configurado.

 

Cause

O host do Solaris não conseguiu atribuir e manter portas com a mensagem "connection ports: 0-0

 

Resolution

Atualize as portas de conexão usadas no client.

  1. Faça log-in no client como root.

  2. Execute o seguinte nsrports Comando para definir o intervalo de portas de conexão do padrão (0-0) para o intervalo de portas legado (10001-30000):
    nsrports -C 10001-30000

  3. Verifique a nova configuração de porta executando nsrports sem bandeiras adicionais.

[root@lnx-client02]:~# nsrports
Service ports: 7937-9936
Connection ports: 10001-30000

 

Solução alternativa: Interromper os daemons do NetWorker no client e usar kill para encerrar todos os daemons restantes e, em seguida, iniciar os daemons permite que os backups funcionem por algum tempo.
