Network will be unavailable when two NICS are configured for PDSA

Troubleshooting

Problem

When two Network Interface Cards (NICs) are configured with two networks in different network segments, where one is connected to a Local Area Network (LAN) and the other is connected to a Wide Area Network (WAN), the two networks interfere with each other, and the network to the WAN in Dynamic System Analysis (DSA) Preboot is not stable

The system has the symptom described above.

Solution

This issue has been fix in Preboot DSA version 9.28 AA4.

The file is or will be available by selecting the appropriate Product Group, type of System, Product name, Product machine type, and Operating system on IBM Support's Fix Central web page, at the following URL:

Workaround

Do not configure NICs with different network segments at the same time.

Additional information

If users do not configure more than one NIC with different network segments at the same time, the networks do not interfere with each other, therefore, the network to WAN remains stable.
