Results
If these steps do not resolve the problem, it is probably a problem with the compute node. See
“Connectivity problems” on page 450 for more information.
Solving shared power problems
Problems with shared resources might appear to be in the compute node, but might actually be a
problem in a IBM Flex System Enterprise Chassis power component.
About this task
To check the general function of shared power resources, complete the following steps:
Procedure
1.
Verify that the LEDs on all the power modules of the IBM Flex System Enterprise Chassis are lit.
2.
Verify that power is being supplied to the IBM Flex System Enterprise Chassis.
3.
Verify that the installation of the compute node type is supported by the IBM Flex System Enterprise
Chassis.
4.
Verify that the power configuration of the IBM Flex System Enterprise Chassis supports the bay
where your compute node is installed.
5.
Verify that the power management configuration and status of the IBM Flex System Enterprise
Chassis support compute node operation.
See the information center for your management module or the Management Module User's Guide or
the Management Module Command-Line Interface Reference Guide for more information.
6.
Verify that the local power control for the compute node is set correctly.
See the information center for your management module or the Management Module User's Guide or
the Management Module Command-Line Interface Reference Guide for more information.
7.
Verify that the IBM Flex System Enterprise Chassis blowers are correctly installed and operational.
Solving undetermined problems
When you are diagnosing a problem in the IBM Flex System p270 Compute Node, you must determine
whether the problem is in the compute node or in the IBM Flex System Enterprise Chassis.
About this task
v
If all of the compute nodes have the same symptom, it is probably a problem in the IBM Flex System
Enterprise Chassis.
For more information, see the following documentation:
– Hardware Maintenance Manual and Troubleshooting Guide for your IBM Flex System Enterprise Chassis
– Problem Determination and Service Guide for your IBM Flex System Enterprise Chassis
v
If the IBM Flex System Enterprise Chassis contains more than one compute node and only one of the
compute nodes has the problem, troubleshoot the compute node that has the problem.
Check the LEDs on all the power supplies of the IBM Flex System Enterprise Chassis where the compute
node is installed. If the LEDs indicate that the power supplies are working correctly, and powering off
and powering on the compute node does not correct the problem, complete the following steps:
