Celerra, how do check NSLOOKUP from datamover for name resolutions

Hello,

If I do a plain nslookup from CLI (control station), I believe its the resolution for the control station.

If I want to ensure that the datamover is able to do the name resolutions fine, how can I check?

I believe ping is disabled as they are in DMZ...

[nasadmin@ns960fm1-cs03 ~]$ server_dns server_2
server_2 :
DNS is running.
***.com

proto:udp server(s):10.*.*.*, 10.*.*.*

[nasadmin@ns960fm1-cs03 ~]$ server_ping server_2 -i default_cifs_interface 10.*.*.*

server_2 :

Error 6: server_2 : No such device or address

Thanks in advance..

yes the Linux nslookup on the control station use the control station DNS config which is seperate from the data mover DNS config

There is no customer nslookup command for the data mover but support can help you troubleshoot

I would first look into the data mover log for DNS errors

there is also the nas_checkup command that includes DNS

when changing DNS config and testing dont forget to flush the DNS Cache via server_dns

The error from your Server_ping means it cant figure out what default_cifs_interface is

Thanks for the reply, now everything is back to normal, everything works fine even with those commands not returning anything, could be blocked at the firewall...anyway, let us not worry about that..

thanks again..

unfortunately there is no server_traceroute, no server_nslookup.  See if you can ping (server_ping) the gateway for the DMZ network.

You can confirm that your DNS settings point to (and can reach) a real DNS server using server_checkup:

$ server_checkup server_2 -test CIFS -subtest DNS
