HI 2 Every1,

I am facing majore issue while running load balance config_mpath script.

Excuted command ----> config_mpath --primary --persistent --policy fixed --access xxxxxfas001:root:xxxxx --access xxxxxfas002:root:xxxxx

Error:

WARNING:
   Your DNS is improperly configured.
   The following storage system hostname(s) could not be resolved:
        xxxxxfas001
       xxxxxfas002

   After the DNS issues are resolved, you must properly
   configure the preferred paths for NetApp storage systems
   by running the following command:
      /opt/netapp/santools/config_mpath --primary --loadbalance --persistent

Note: DNS is configured properly . With same DNS entires i am able to excuted the load balancer config_mpath script in othere environment into the same domain sucessfulluy.

Hi,

Are you able to ping the filers by name from the host? Is the firewall turned on?

I am assuming this is an esx host in which case you could install the NetApp VSC see this post http://communities.netapp.com/message/18638

With it you can set the MPIO settings

I think the syntax for the config_mpath command is --access <filerXX>:<password> , though I do not think that is the issue.

You also need to add the esx host to the hosts.equiv file on the filer

The format in the file is

<ESX_host> root

If it still complains about dns, try adding the filer names/ip's the /etc/hosts on the ESX server
