Hot-Plug Module With Pcie Error Isolation Mode Enabled - Hitachi Compute Blade 2000 User Manual

We recommend that you configure Hardware Memory Dump in addition to the OS
dump functionality so that you can get memory dump in more situations.
See "Hardware Memory Dump" in "Chapter 5: Server Blade Setup" for the
instructions to use Hardware Memory Dump.
See the Red Hat, Inc. website for details of kdump.
Hot-plug module with PCIe error
isolation mode enabled
 Applying a hot-plug module
When the PCIe error isolation mode is enabled with Linux, the OS will keep running
if the device is isolated and not available at a PCIe failure. If the hot-plug module
"acpiphp" has not been loaded then, the device remains on the OS, causing
inconsistency between current states of the device and the OS.
Apply the hot-plug module to avoid the trouble described above.
 Target system requirements
The following requirements apply to a target system.
 The OS is one of those below:
Red Hat Enterprise Linux 5.4 (x86, AMD/Intel 64)

Red Hat Enterprise Linux 5.4 Advanced Platform (x86, AMD/Intel 64)

 PCIe Error Isolation is enabled in PCI Error Handling Mode.
 How to change settings
1 Create acpiphp.modules.
Perform the following command:
# vi /etc/sysconfig/modules/acpiphp.modules
The following shows the edited content.
#/bin/bash
/sbin/modprobe acpiphp
Save the edited content, and configure the privilege using the OS chmod
command.
