Issue

  •     Nodes could not connect to the DNS servers and could not resolve any of the following host names.

  • verify: (3 options)

1. Run command  Autosupport history show 

::>system autosupport history show::>system autosupport history show -node <node_name>  -fields node,seq-num,status,error,destination


Last Error reported : Couldn't resolve host name.

2.  Testing connectivity from the command line

::> set advanced
::> system node autosupport check show-details -node node_name

example:

Category: smtp
          Component: mail-server
             Status: failed
             Detail: SMTP connectivity check failed for destination:
                     mailhost. Error: Could not resolve host - 'mailhost'
  Corrective Action: Check the hostname of the SMTP server

3. review the notifyd logs.

::> node run -node (node-name) -command rdfile /etc/log/mlog/notifyd.log
