Rodrigo, muito obrigado pelo artigo, me ajudou bastante e consegui passar do
erro. O nslookup consegue resolver todos os hosts tanto do nó1 como do nó2
(pub, priv, vip, scan), conforme o artigo mostra.
Porém, no final da instalação, nas checangens do pré-requisito me aparece o
seguinte:
Task resolv.conf Integrity FAILED Check Failed on Nodes: [rac2, rac1]
MORE DETAILS
Verification result of failed node: rac2 Details: - PRVF-5636 : The DNS
response time for an unreachable node exceeded "15000" ms on following nodes:
rac1,rac2 - Cause: The DNS response time for an unreachable node exceeded the
value specified on nodes specified. - Action: Make sure that ''options
timeout'', ''options attempts'' and ''nameserver'' entries in file resolv.conf
are proper. On HPUX these entries will be ''retrans'', ''retry'' and
''nameserver''. On Solaris these will be ''options retrans'', ''options retry''
and ''nameserver''. Make sure that the DNS server responds back to name lookup
request within the specified time when looking up an unknown host name. - ;;
connection timed out; trying next origin ;; connection timed out; no servers
could be reached - Cause: Cause Of Problem Not Available - Action: User
Action Not Available - Check for integrity of file "/etc/resolv.conf" failed

Entao...
O que o instalador do Oracle faz é usar o nslookup (utilitario do linux)
para checar os nomes e se está usando dns. O que eu fiz foi pegar um script
linux pronto na net e aí troquei o nslookup original por ele, quando o
instalado do Oracle faz a chamada, ele chama o script já ajustado para simular
a resposta de um dns.

Mas como estou começando meus estudos e meus aprendizados com RAC, eu não
entendi o que você quis dizer.

Vc renomeia o nslookup e o substitui por um shell script... da uma googlada

Obs: Em cada VM, eu tenho 3 adaptadores de rede, a primeira NAT, a segunda Host

As maquinas RAC1 e RAC2 se comunicam pela rede PUBLICA e pela rede PRIVADA
(pingando pelo IP ou pelo host).
Mas se eu pingar o endereço virtual ou pelo SCAN, não funciona.
Quando eu chego na instalação do GI na parte GRID PLUG and PLAY information, o
erro abaixo é gerado:
[INS-40718]
Single Client Access Name (SCAN): rac-scan.localdomain could not be resolved.
Alguém sabe como posso resolver essa situação?
