Symptoms

This issue could possibly be seen on any T3-x or T4-x servers / blades.
T4-x, redstate error:

In this example this System automatically powered down due to redstate condition, resulting in the following errors seen:

[CPU 0:2:5] ERROR: Redstate trap occurred on node 0 strand 21.
[CPU 0:2:5] ERROR: Powering down due to Redstate

ERROR
-----------------------
[CPU 0:2:5] ERROR: Redstate trap occurred on node 0 strand 21.

[CPU 0:2:5] ERROR: Powering down due to Redstate

BUSINESS IMPACT
-----------------------
Due to this kind of issue, users cannot boot disk, cdrom and the server won't poweron.

Changes

Cause

A CPU(s) encountered an error on a particular Node and Strand which caused a Redstate trap to occur:

The following was seen during a reboot on a T4-1

[CPU 0:2:5] ERROR: Redstate trap occurred on node 0 strand 21.

[CPU 0:2:5] ERROR: Powering down due to Redstate

Received redstate error message when rebooted and system automatically powered down due to redstate condition

Solution

The CPU is embedded on the following T4-x servers/blades:

T4-1 - CPU is mounted on the motherboard and the motherboard needs to be replaced.

T3-1 - CPU is mounted on the motherboard and the motherboard needs to be replaced.

T3-1B - CPU is mounted on the motherboard and the blade needs to be replaced.

T4-2 - The 2 CPU's are mounted on the motherboard and the motherboard needs to be replaced.

T3-2 - The 2 CPU's are mounted on the motherboard and the motherboard needs to be replaced.

T4-4 - The 4 CPU's are divided on to 2 PM modules. PM0 houses CPU 0&1 and PM1 houses CPU 2&3. Replace the PM module corresponds to the CPU that got the redstate.

T3-4 - The 4 CPU's are divided on to 2 PM modules. PM0 houses CPU 0&1 and PM1 houses CPU 2&3. Replace the PM module corresponds to the CPU that got the redstate.

This type of Red State error is not to confuse with Red States errors with memory or PCI cards.

Issues with Memory and pci cards, the system would still be able to power-on and most times boot. If you are detecting Red State errors w/memory and or PCI please have L2 review
