Resolving The Problem

Source

Retain tip H067134

Symptom

The IBM Netfinity Ethernet 10/100 adapter 2 and the Netfinity 10/100 Fault Tolerant adapter failover pairs in the same system experience conflicts and cause the system to hang.

Affected configurations

The system is any of the following IBM eServer xSeries servers:

  • An xSeries 340, type 8656, any model
  • An xSeries 240, type 8664, any model
  • An xSeries 230, type 8658, any model
  • An xSeries 200, type 8478, any model

The system is any of the following IBM Netfinity servers:

  • A Netfinity 8500R server, type 8681, any model
  • A Netfinity 7600 server, type 8665, any model
  • A Netfinity 7100 server, type 8666, any model
  • A Netfinity 6000R server, type 8682, any model
  • A Netfinity 5600 server, type 8664, any model
  • A Netfinity 5500 M20 server, type 8662, any model
  • A Netfinity 5100 server, type 8658, any model
  • A Netfinity 5000 server, type 8659, any model
  • A Netfinity 4500R server, type 8656, any model
  • A Netfinity 3500 M20 server, type 8657, any model
  • A Netfinity 3000 server, type 8476, any model
  • A Netfinity 1000 server, type 8477, any model
  • A Netfinity A100 server, type 8652, any model

The system is configured with the following options:

  • An IBM Netfinity Ethernet 10/100 adapter 2, option part number 34L1501, replacement part number (FRU) 34L1509
  • An IBM Netfinity 10/100 Fault Tolerant adapter, option part number 08L3341, replacement part number (FRU) 25L4837

The following network operating systems (NOS) are affected:

  • Novell 4.2, with any support pack applied
  • Novell 5.x, with any support pack applied
Workaround

Use either two of the IBM Netfinity Ethernet adapter 2 cards or two IBM Fault Tolerant adapters in failover pairs.
 
Note: Do not use one of each type. The failover pair should be two identical adapters.

Additional information

This defect is caused by an incompatibility between the persistence mode of the Intel driver for the Netfinity Ethernet 10/100 adapter 2 and the reload functions of the Fault Tolerant adapter. Because of this incompatibility, the configuration is not supported.
