OS to iDRAC Pass Through is new feature being provided from iDRAC 1.30.30 release onward, which enables you to access iDRAC from host OS using high speed network channel. You can access iDRAC from the host operating system even if iDRAC and host are in different Network. No separate system is required to configure/access iDRAC functionality.
OS to iDRAC Pass Through will work on shared LOM (rack and tower servers) and dedicated NIC (rack, tower and blade servers).
Once the OS to iDRAC Pass Through channel is enabled, the end users can access the iDRAC using iDRAC IP from the Host OS.
To use this feature you need to make sure:
1. At least one LOM port of NDC/LOM should be connected to the switch.
2. The Connected NDC/LOM should be Pass Through capable. (We can verify this by running Racadm command: “Racadm get idrac.os-bmc.PTCapability”)
You need to do following minimal configuration in order to use this OS to iDRAC pass through feature. Any user with iDRAC configure Privilege will be able to configure this feature. Minimum iDRAC license require to use this feature is Express.
1 Enable OS to iDRAC Pass-Through
2. Specify OS IP Address, if iDRAC network is configured for dedicated mode
Note: If more than one LOM is active, enter the first LOM’s IP address.
The above configuration can be done through iDRAC GUI, Racadm, WSMAN or iDRAC Settings Utility.
