Goal

These messages will only appear in the System Controller console of Sun Fire[TM] V1280/E2900/3800/48x0/E4900/6800/E6900 platforms, and this document aims to explain what these messages mean.

Logs appearing will be similar to the following:

0x1ee9448 (tNetTask): arptnew failed on 0
0x1ee9448 (tNetTask): arptnew failed on 0
0x1ee9448 (tNetTask): arptnew failed on 0
0x1ee9448 (tNetTask): arptnew failed on 0

Solution

>>> 0x1ee9448 (tNetTask): arptnew failed on 0

A message from tNetTask "arptnew failed on xxxxxxxx" where xxxxxxxx is the hexadecimal representation of an IP address is similar to the previous error, indicating some kind of routing configuration problem.

In this instance, the system controller was not able to identify the address "0x1ee9448"

The "failed on '0'" does not make sense as it did not return a valid IP address to this system controller.

These messages would be an issues with the external Network/Switch, providing the SC with invalid address to translate.

The Customer Network Admin should look into these settings and maybe remove or block this address from reaching the SC

Also, do take note that, the SC should not be in a public network

Please ignore the above message events as the system controller is not faulty.

Background

ARP is the protocol used by Ethernet to translate the remote node's IP address to a MAC address (which is required before sending unicast ethernet frames on the network).
0x1ee9448 is translated from Hexadecimal to Decimal as such

01 = 1
ee = 238
94 = 148
48 = 72

1.238.148.72
