Applies to

  • ONTAP 9.x
  • Service-Processor (SP)
  • Domain Name Service (DNS)

Issue

Data ONTAP has an instance of asupd that lives on the SP to enable the system to send out Auto Support logs, as well as core dumps, in the event that a node is down. This is the reason name resolution is set on the SP. However, DNS information is not manually configured on the SP, it is propagated from ONTAP. In rare situations, such as after deleting DNS server entries, a stale entry of the old IP maybe left in /etc/resolv.conf causing the SP to probe the wrong IP. To check contents of /etc/resolv.conf in ONTAP 9 login to the SP interface  and run sp status -d.

Example Output:
 
cat /etc/resolv.conf
====================
# sp-auto-generated by rlm_conf.sh invoked by configd
search test.netapp.com eng.netapp.com test.netapp.com netapp.com
nameserver 10.61.80.123
nameserver 10.61.80.122
