I see the messageThe 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
congured 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 congured 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 rst one in
routing order.
Table 8. Details
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 rst
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.
