iDRAC Service Module uses the OS to iDRAC pass-through over USB NIC feature to establish the communication with iDRAC.
Sometimes, the communication is not established though the USB NIC interface is configured with the correct IP endpoints. This
may happen when the host operating system routing table has multiple entries for the same destination mask and the USB NIC
destination is not listed as the first one in 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 USB NIC interface. The link-local destination mask is repeated and the USB NIC is not the first
one in the 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, make sure that the iDRAC USBNIC IPv4 address (by default it is 169.254.0.1) is
reachable from the host operating system.
If not:
• Change the iDRAC USBNIC address on a unique destination mask.
• Delete the entries that are not required from the routing table to make sure that USB NIC is chosen by route when the host
wants to reach the iDRAC USB NIC IPv4 address.
On iDRAC Service Module version 2.0 and earlier, when uninstalling iDRAC Service Module from a VMware ESXi server, the
virtual switch is named as vSwitchiDRACvusb and port group as iDRAC Network on the vSphere client. How to delete them?
While installing iDRAC Service Module VIB on a VMware ESXi server, iDRAC Service Module creates the vSwtich and Portgroup to
communicate with iDRAC over the OS to iDRAC Pass-through in USB NIC mode. After the uninstallation, the virtual switch
vSwitchiDRACvusb and the port group iDRAC Network are not deleted. To delete it manually, perform one of the following steps:
• Go to vSphere Client Configuration wizard and delete the entries.
• Go to the Esxcli and type the following commands:
– To remove port group:
esxcfg-vmknic -d -p "iDRAC Network"
– To remove vSwitch:
esxcfg-vswitch -d vSwitchiDRACvusb
NOTE: You can reinstall iDRAC Service Module on the VMware ESXi server as this is not a functional issue for the
server.
Where is the Replicated Lifecycle log available on the operating system?
To view the replicated Lifecycle logs:
Operating System Location
Microsoft Windows
Event viewer → Windows Logs → System . All the iDRAC
Service Module Lifecycle logs are replicated under the source
name
iDRAC Service Module .
NOTE: In iSM version 2.1 and later, Lifecycle logs are
replicated under the Lifecycle Controller Log source
name. In iSM version 2.0 and earlier, the logs are
replicated under iDRAC Service Module source name.
