Table 64. Example of a routing order (continued)
Destination Gateway Genmask Flags Metric Ref Use Iface
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:
Table 65. Lifecycle logs location
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.
NOTE: The location of the Lifecycle log can be configured
using the iDRAC Service Module installer. You can
configure the location while installing iDRAC Service
Module or modifying the installer.

What are the Linux-dependent packages or executables available for installation while completing the Linux
installation?
