Uninstallation

Use rpm command to uninstall Machine Check Monitoring Service.

Uninstall packages mcemonitor, capmonitor, and acpi_call in order.

3.4.1

Uninstalling acpi_call

1.

Login to the target machine as a root user.

2.

Uninstall acpi_call RPM package of Machine Check Monitoring Service using rpm command.

# rpm -e mcl-acpicall-2.4-3.01.2.6.32.504.23.4.el6.x86_64

Note: mcemonitor and capmonitor must be uninstalled before uninstalling acpi_call.

If acpi_call is uninstalled while mcemonitor and capmonitor have not been uninstalled,
the following message is output and uninstallation of acpi_call fails.

# rpm -e mcl-acpicall-2.4-3.01.2.6.32.504.23.4.el6.x86_64

error: Failed dependencies:

mcl-acpicall is needed by mcl-capmonitor-2.4-2.12.el6.x86_64

mcl-acpicall is needed by mcl-mcemonitor1-2.4-2.02.el6.x86_64

3.

Confirm that acpi_call RPM package of Machine Check Monitoring Service is uninstalled
correctly. Uninstallation completes successfully if "acpi_call" is not displayed as shown below.

# rpm -qa | grep acpicall

4.

Check if acpi_call driver is uninstalled correctly. If the 3 acpi_call are not displayed, acpi_call
driver is uninstalled correctly.

# lsmod | grep acpi
