On iDRAC Service Module version 2.0 and earlier, while installing the iDRAC Service Module, an error message
is displayed stating this is not a supported server. Consult the User Guide for additional information about the
supported servers. How to resolve this error?
Before installing the iDRAC Service Module, make sure that the server is a 12th generation PowerEdge server or later. Also,
make sure that you have a 64-bit system.
The following message is displayed in the OS log, even when the OS to iDRAC Pass-through over USBNIC is
configured properly. Why?
The iDRAC Service Module is unable to communicate with iDRAC using the OS to iDRAC Pass-through channel
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.
Table 66. Example of a 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
169.254.1.1) 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:

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.
