From Alerts

Time (UTC ): 11/24/2016, 11:28:22 AM
Severity : Error
Message ID:14:603b8
Message: DNS servers configured for the DNS client of NAS server examplenas01 are not reachable.
Description: DNS servers configured for the NIS client of the NAS server are not reachable. Check network connectivity.
Ensure that at least one DNS server is running and the storage system can access it.
Acknowledged: No

 

Cause

DNS Servers defined in the NAS Server Configuration are not reachable by that NAS server.

From the Dell Unity service shell ping, nslookup or dig can be used to perform some checks.

PING Example
Where NAS Server is assigned IP 192.168.1.xxx, and DNS Server is 192.168.2.xxx.
Using ping with "-I" to specify the NAS Server NIC to send the ping from.

service@none spa:~>  ip addr show | grep 192.168.2.xxx
    inet 192.168.1.xx/24 scope global secondary eth10

service@none spa:~> ping -I eth10 192.168.2.xxx -c 2
PING 192.168.2.xxx (192.168.2.xxx) from 192.168.1.xx eth10: 56(84) bytes of data.
64 bytes from 192.168.2.xxx: icmp_seq=1 ttl=127 time=1.02 ms
64 bytes from 192.168.2.xxx: icmp_seq=2 ttl=127 time=0.916 ms

--- 192.168.2.xxx ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 1000ms
rtt min/avg/max/mdev = 0.916/0.970/1.024/0.054 ms
 service@none spa:~>

Nslookup Example:
Using a specific DNS server to run the query against.

service@none spa:~> nslookup
> server 192.168.2.xxx
Default server: 192.168.2.xxx
Address: 192.168.2.xxx#53
> examplenas01
;; connection timed out; no servers could be reached
> exit
service@none spa:~>

DIG Example:

service@none spa:~> dig @192.168.2.xxx examplenas01

; <<>> DiG 9.9.9-P1 <<>> @192.168.2.xxx examplenas01
; (1 server found)
;; global options: +cmd
;; connection timed out; no servers could be reached
service@none spa:~>

 

Resolution

Connectivity to one or more DNS Servers must be checked and that the DNS Server is responding to requests.

For reliability and performance multiple DNS should be defined for use by the NAS Server to avoid a single point of failure in the environment.

When multiple DNS servers are defined for a NAS Server, if one is not responding the status in the UI is shown with a white "i" on Blue Circle, = OK (But).

This indicates: "The object is operating normally but there are potential issues."
