iDRAC: Configure and troubleshoot the iDRAC service module

Summary: Learn to configure and troubleshoot the IDRAC service module (ISM), including OS Passthrough, network interface checks, and TLS handshake issue resolution.


iDRAC Service Module Basics:

Features:

  • Lightweight OS Agent
  • This feature allows iDRAC to talk to OS over an internal USB Network Interface Controller
  • This feature allows the iDRAC to launch without an IP
  • This feature can reboot host during lock-ups or other troubleshooting steps
  • Replicate Lifecycle Controller Logs to OS for log scraping tools
  • S.M.A.R.T. monitoring

ISM Versions:

  • The OS DUP is the embedded version in the iDRAC, which allows to upload the contents to the iDRAC
  • This is the version to install in the OS, and supports Linux, Windows, and ESXi.


ISM installation

Requirements

  • OS-BMC Passthrough enabled on the iDRAC
  • This is the USB Network Interface that is in the OS and must use the APIPA Address.
  • This is the USB Network Interface IP with the default IP of 169.254.0.2 that must be able to ping 169.254.0.1.
  • IDRAC7 or newer
  • Some ISM Versions require a minimum iDRAC Firmware revision to be installed.
  • ISM 3.4 and newer require a TLS handshake if the iDRAC9 firmware supports the use of TLS.

ISM Installs for a Windows Operating System.

  • Download the ISM .exe
  • Run it on the host, it self-extracts by default to C:\OpenManage\ISM\windows
  • Run the iDRACSvcMod.msi

ISM Installs for Linux:

  • Download the ISM tar.gz file and SCP it to the Linux operating system
  • Tar –zxvf ISM.tar.gz
  • Run the setup.sh
  • Type the number for all features(10 on newest release) and press Enter

ISM Installs on an ESXi host:

  • Download the ISM .zip file and SCP it to any patch, such as /tmp
  • Install the ESXcli software using the following command: vib install –d /tmp/ISM.zip


ISM Troubleshooting

Windows

  • Check iDRAC for OS Passthrough being enabled for USB
  • Check ncpa.cpl for Remote NDIS Device

Note: The most common Windows failure is a missing NDIS Device or an unsupported IP Is assigned to the network interface controller (NIC).

  • Run ipconfig /all and find out the IP Address of this NIC
  • Ensure that the user can ping the IDRAC 169.254.0.1 IP
  • Reboot the iDRAC and then reinstall iSM. Then reboot the iDRAC again if it still shows Not Running
  • If the issue persists, then check the OS Audit logs for errors. Something is blocking TLS Handshake.

Linux

  • Check iDRAC for OS Passthrough being enabled for USB
  • Run ip addr to see the NIC is present and assigned an APIPA address

Note: The most common issue is that USB is blocked.

  • Ensure that the user can ping the IDRAC 169.254.1.1 IP
  • Reboot the iDRAC and then reinstall iSM. Then reboot the iDRAC again if it still shows Not Running
  • If the issue persists check /opt/dell/srvadmin/iSM/etc/rceclient.p12 to ensure that the TLS cert exists then engage SST

ESXi

Note: Run tail -f /var/log/syslog.log | grep -i dcism during the install process so the user can follow the progress.

  • Check iDRAC for OS Passthrough being enabled for USB
  • Check that the NIC exists by running the following command: esxcli network ip interface list
  • This should show a virtual USB Nic named “vSwitchiDRACvusb”

Example:

vmk2  Name: vmk2  MAC Address:  Enabled: true
  • Since the vUSB NIC is listed as vmk2, check its IP address using the following command:

esxcli network ip interface ipv4 get -i vmk2

  • Ensure that the user can ping the IDRAC 169.254.0.1 IP
  • If that works stop the service: /etc/init.d/dcism-netmon-watchdog stop
  • Now start it with the Installed switch: /etc/init.d/dcism-netmon-watchdog start install
  • Reboot the iDRAC
  • Rerun the TLS Handshake if the issue persists: /opt/dell/srvadmin/iSM/bin/Invoke-iSMPKIHelper-install
  • Ensure that the certificate is created and stored in the following path: /etc/cim//dell/srvadmin/iSM/rceclient.p12
