Dell EMC iDRAC Service Module 3.1 User’s Guide

Frequently asked questions

This section lists some frequently asked questions about the iDRAC Service Module.

Do I need to uninstall Open Manage Server Administrator before installing or running the iDRAC Service Module?

No. Before you install or run the iDRAC Service Module, ensure that you have stopped the features of Server Administrator that the iDRAC Service Module provide.
  • NOTE: Uninstalling the Server Administrator is not required.

How do I know that the iDRAC Service Module is installed in my system?

To know if the iDRAC Service Module is installed on your system,
  • On Windows:

    Run the service.msc command. Find from the list of services if there is a service by name DSM iDRAC Service Module.

  • On Linux:

    Run the command /etc/init.d/dcismeng status. If the iDRAC Service Module is installed and running, the status displayed will be running.

  • NOTE: Use the systemctl status dcismeng.service command instead of the init.d command to check if the iDRAC Service Module is installed on RedHat Enterprise Linux 7 and SUSE Linux Enterprise 12 operating system.

How do I know which version of the iDRAC Service Module I have in my system?

To check the version of the iDRAC Service Module in the system, click Start > Control Panel > Programs and Features . The version of the installed iDRAC Service Module will be listed in the Version tab. You can also check the version by go to My Computer > Uninstall or change a program .

What is the minimum permission level required to install the iDRAC Service Module?

To install the iDRAC Service Module, you must have Administrator level privileges.

Whenever I try to install the iDRAC Service Module, it shows an error message This is not a supported server . Consult the User Guide for additional information about the supported servers. What should I do now?

Before installing the iDRAC Service Module, ensure that the server or the system on which the iDRAC Service Module is to be installed is a Dell’s 12 th generation PowerEdge server or later. Also make sure that you have a 64-bit system.

I see the message The iDRAC Service Module is unable to communicate with iDRAC using the OS to iDRAC Pass-through channel in the OS log, even when the OS to iDRAC Pass-through over USBNIC is configured properly. Why do I get this message?

iDRAC Service Module uses the OS to iDRAC Pass-through over USBNIC to establish communication with iDRAC. Sometimes, the communication is not established though the USBNIC interface is configured with correct IP endpoints. This may happen when the host OS routing table has multiple entries for the same destination mask and the USBNIC destination is not listed as the first one in routing order.
Table 1. Details. The following table provides information about the routing order.
Destination Gateway Genmask Flags Metric Ref Use Iface
default 10.94.148.1 0.0.0.0 UG 1024 0 0 em1
10.94.148.0 0.0.0.0 255.255.255.0 U 0 0 0 em1
link-local 0.0.0.0 255.255.255.0 U 0 0 0 em1
link-local 0.0.0.0 255.255.255.0 U 0 0 0 enp0s20u12u3
In the example enp0s20u12u3 is the USBNIC interface. The link-local destination mask is repeated and the USBNIC is not the first one in order. This results in the connectivity issue between iDRAC Service Module and iDRAC over the OS to iDRAC Pass-through. To troubleshoot the connectivity issue, you can perform one of the following steps:
Ensure that the iDRAC USBNIC IPv4 address (by default it’s 169.254.0.1) is reachable from the host OS. If not:
  • Change the iDRAC USBNIC address on a unique destination mask.
  • Delete the unwanted entries from the routing table to ensure USBNIC is chosen by route when the host wants to reach the iDRAC USBNIC IPv4 address.

Whenever I try to install the iDRAC Service Module, an error message This operating system is not supported is displayed.

The iDRAC Service Module can be installed only on the supported operating systems. For information on operating systems that are supported, see Supported operating systems .

I used the remote iDRAC hard reset feature to reset the iDRAC. However, the IPMI drives is unresponsive and I am not able to troubleshoot.

If you try to use the remote iDRAC hard reset feature on VMware ESXi 5.5 U3 or ESXi 6.0 U1, the IPMI drivers becomes unresponsive, because of this the iDRAC Service Module communication is stopped. You may have to reboot the server and load the IPMI driver again to resolve the issue.

Where do I find the Replicated LifeCycle log on my Operating System?

To view the replicated LifeCycle logs:
Table 2. Frequently asked question . Operating system location.

Operating System

Location

Microsoft Windows Event viewer > Windows Logs > <Existing group or Custom folder> . All the iDRAC Service Module LifeCycle logs are replicated under the source name iDRAC Service Module.
Red Hat Enterprise Linux, SUSE Linux, CentOS, and Citrix XenServer /var/log/messages
VMware ESXi /var/log/syslog.log

What is the default SNMP protocol configured in iDRAC Service Module to send alerts in Linux operating systems?

By default, the SNMP multiplexing protocol (SMUX) is configured in iDRAC Service Module to send alerts.

SMUX is not supported on my system. Which protocol should I configure to send alerts?

If SMUX is not supported on your system, Agent-x is used as a default protocol.

How do I configure iDRAC Service Module to use the Agent-x protocol to send alerts by default?

You can configure Agent-x as the default protocol using ./Enable-iDRACSNMPTrap.sh 1/agentx –force command. If –force is not specified, ensure that the net-SNMP is configured and restart the snmpd service.

What are the Linux-dependent packages or executables I should install while completing the Linux installation?

To see the list of Linux-dependent packages, see Linux dependencies.

I created a custom folder in Windows Event Viewer, but the LC logs are not replicated in my custom folder. What do I have to do now to replicate the LC logs?

Ensure to close the Windows Event Viewer after creating the custom folder. Open the Windows Event Viewer again to view the replicated LC logs.

I chose custom install option from the Graphical User Interface during iDRAC Service Module installation and disabled a feature, but I am not able to enable the feature using any of the other interfaces. How do I enable the feature again?

On systems running Microsoft Windows operating system, a feature that is enabled using the installer and disabled using any interface other than the installer, can only be enabled using the same interface or the installer in Graphical User Interface mode.

For example, you may not be able to enable a feature using the RACADM CLI commands, that was disabled from the Graphical User Interface during iDRAC Service Module installation.

I am not able to access the iDRAC page through the host OS as an Active Directory user over LDAP. I am trying to access the iDRAC page through the host OS, but I get an error saying that the site cannot be reached. How do I troubleshoot the issue?

When you are trying to access the iDRAC page through the host OS, you may get an error saying that the site cannot be reached. Ensure that the iDRAC network is configured for authentication as an LDAP user. You can also login as a local user or a guest.

I am not able to access the iDRAC page through the host OS after performing an iDRAC factory reset operation, such as racadm racresetcfg. How do I troubleshoot the issue?

Ensure that the OS to iDRAC passthru channel is enabled. By default, it is disabled in factory mode. To enable the OS to IDRAC passthru channel on iDRAC, use the following command, racadm set idrac.os-bmc.adminstate 1 .

I am seeing the past Life Cycle Logs (LCL) alerts targeted for SNMP traps replicated in Operating System logs. Can I troubleshoot the issue?

iSM will not be able to distinguish between the past Life Cycle Log (LCL) alerts targeted for SNMP traps and past LCL alerts targeted for OS Logs. Hence user may see past LCL alerts targeted for OS Logs in SNMP traps as well and vice versa.

I am seeing 169.254.0.2 as the source IP address in the iDRAC SNMP trap received via iSM. How do I troubleshoot the issue?

On Linux OS, the iDRAC SNMP traps received via Host OS displays the hostname or source IP address as 169.254.0.2 instead of the actual Host OS name or IP address. This is decided by the OS to populate the entry before rendering the trap to the user.

I have configured OS to iDRAC pass-through to LOM and when I try to run dcism-sync, the update operation fails. What can be done?

OS to iDRAC pass-through should be configured to USB-NIC mode. This is a pre-requisite for iDRAC Service Module installation and update.
