Error code

Description

Recommended actions

200

Unspecified hardware problem.

Reseat the network interface card.

If the problem persists, contact Network Appliance support.

201

Link not detected.

Complete the following steps until you detect a link:

  1. Ensure that there is a cable connecting the network interface card to the network.
  2. Check the cable.
  3. Check the interface card and corresponding switch port setting for a speed mismatch.
  4. Check for a switch or hub port problem.
  5. Reseat the network interface card.
  6. If the problem persists, contact Network Appliance support.

202

A link on an Alteon Gigabit adapter is not detected because of an autonegotiation mismatch.

Change the interface configuration or peer switch port configuration so that the settings match.

203

No link is detected because of a speed mismatch.

Change the interface configuration or peer switch port configuration to match the speed.

204

The interface not configured up.

Configure the interface up.

205

Duplex mismatch.

Change the interface or peer switch port duplex setting so they match.

206

Link capacity problem.

Upgrade to a faster interface.

207

The interface not transmitting or receiving.

Complete the following steps:

  1. Pull out the network cable from the network interface card.
  2. Reinsert the cable.
  3. Change the media type using the ifconfig command, wait five seconds, then restore the media type to the previous setting.
  4. If the problem persists, contact Network Appliance support.

208

Excessive I/O errors.

Complete the following steps:

  1. Reseat the interface card.
  2. Check the cables.
  3. If the problem persists, contact Network Appliance support.

209

Excessive unsupported protocol packets are sent to the filer.

The problem is not with your filer.

Contact your network administrator to resolve the problem.

301

The IP address and netmask are inconsistent with the assigned broadcast address.

Change the configuration using the ifconfig command.

302

The broadcast address reaches a larger set of hosts than the standard broadcast computed from the IP address and netmask.

If this behavior is erroneous, change the configuration.

303

Excessive IP reassembly errors.

Switch from NFS over UDP to NFS over TCP.

401

The TCP window advertised by the client is too small.

The problem is not with your filer.

Reconfigure the client.

402

Excessive packet loss on the sending side.

The problem is not with your filer.

Examine the network and client for congestion.

403

Excessive packet loss on the receiving side.

The problem is not with your filer.

Examine the network and client for congestion.

404

Poor average TCP packet size on the receiving side because the network, client, or both are not enabled to support jumbo frames.

The problem is not with your filer.

Enable support for jumbo frames in network devices and the client.

405

Poor average TCP packet size on the receiving side because of a problem with the network, client, or both.

The problem is not with your filer.

Examine the network and client for configured MTUs.

406

Poor average TCP packet size on the receiving side because of a client application problem.

The problem is not with your filer.

Examine the client application data transmission strategy.

407

Excessive TCP listen socket drops because the system is overloaded or under security attack.

Contact your network administrator to resolve the problem.

408

Excessive filtered TCP port drops because the system is under security attack.

Check your network.

Contact your network administrator to resolve the problem.

409

Excessive embryonic TCP connection drops because the system is under security attack or because a client has a bug.

Contact your network administrator to resolve the problem.

A packet trace might assist in locating the problem.

410

Excessive TCP checksum errors because of a client or a network that loses packets when loaded.

The problem is not with your filer.

  • Check your client system for bugs.
  • Your network might be overloaded.
  • Contact your network administrator to resolve the problem.

411

Bad packets because of a client. Your system might be under a security attack.

The problem is not with your filer.

  • Check your client system for bugs.
  • Check for a security attack.

451

Excessive UDP checksum errors.

Switch from NFS over UDP to NFS over TCP.

601

The DNS server is not reachable.

Examine the DNS server and the path to the DNS server.

602

The NIS server is not reachable.

Examine the NIS server and the path to the NIS server.
