Solution 2250361.1 : After CPU Replacement on X6-2 Servers bdacheckcluster May Report "ERROR: Wrong number of CPU cores"

Applies to:

Big Data Appliance X6-2 Hardware - Version All Versions and later
Linux x86-64

Symptoms

After CPU replacement on X6-2 servers bdacheckcluster may report:

bdanode0x: ERROR: Wrong number of CPU cores : 86
bdanode0x: INFO: Expected number of CPU cores : 88

CPU replacement on X6-2 servers will not always cause bdacheckcluster to raise the error above.

Cause

For a description on the cause see: After SPX86A-8000-TL fault, bdacheckhw Command Reports Wrong Number of CPU Cores (Doc ID 2294697.1).

BUG 25606502 - X6-2L BDA node multiple SPX86A-8000-TL faults at same customer site

Note: If you are noticing this before upgrade, the error should not affect upgrade.

Solution

1. Perform a power cycle on the node.

2. After the power cycle if bdacheckcluster or bdacheckhw still report "ERROR: Wrong number of CPU cores : 86", open an SR with Oracle Support to confirm no hardware issues.
