Troubleshooting Networking Issues

Name Server Unresponsive

Description

All NIS, LDAP, or DNS servers are unreachable or not responding.

Workaround

For each server:

 

1

Ping the server from a client on PowerVault NX3500 subnet and

 

 

verify it responds.

 

2

Issue a request to the server from a client on the PowerVault

 

 

NX3500 subnet and verify it responds.

 

3

Check server logs to see what causes the server not to respond

 

 

to requests.

 

 

 

Specific Subnet Clients Cannot Access the PowerVault NX3500 System

Description

Users (new or old), accessing from specific network(s), cannot

 

access the PowerVault NX3500 system.

Cause

This issue is due to a conflict between the users' subnet addresses

 

and the NAS system internal network's address. The NAS system

 

routes the response packets to the wrong network.

Workaround

1

Check the internal network addresses of the NAS system and verify if

 

 

there is a conflict with the problematic client network addresses.

 

2

If a conflict exists, manually change the conflicting NAS internal

 

 

network address using either the NAS Manager or CLI.
