• In the left pane, click Chassis Overview → PCIe Overview → Setup → Mapping: PCIe Slots to Server Slots. On the Mapping:PCIe Slots to Server Slots page, in the Action column, from the Action drop-down menu, select the appropriate server name,and then click Apply.Note the following:• Without a license, the maximum number of PCIe slots that maybe mapped to a half-height server is two. If a full-height server isinstalled you can map two PCIe slots to the upper server slot and two to the lower (extended) server slot, for a total of four PCIeslots per full-height server.• You can map the server slots to any of the 8 PCIe slots.• A full-height server has both upper and lower mezzanines populated. Else, during POST will stop when the or isdisplayed on the page for you to press any one of the keys.• For full-height servers you can map a maximum of two PCIE slots to upper and two to lower mezzanines. By default, all PCIemappings to server slot 3 will go to the lower mezzanines.• Server slot number is displayed as Slot-01, Slot-02, and so on. For a full-height server, the slot name is displayed as Ext. ofSlot-01, Ext. of Slot-02, and so on.• If you select the host name, then the host name is displayed instead of the slot name.• CMC provides alert capabilities through System Event Log (SEL), SNMP, and Email interfaces.For more information about assigning PCIe devices to a server, see the Online Help.Managing PCIe Slots Using RACADMYou can assign or unassign a PCIe slot to a server by using the RACADM commands. Some of the commands are given here. Formore information about the RACADM commands, see the Chassis Management Controller for PowerEdge VRTX RACADMCommand Line Reference Guide available at dell.com/support/Manuals.• To view the current assignment of PCIe devices to servers, run the following command:racadm getpiecfg -a• To view the properties of PCIe devices by using FQDD, run the following command:racadm getpciecfg [-c ]For example, to view the properties of PCIe device 1, run the following command.racadm getpciecfg -c PCIE.ChassisSlot.1• To assign a PCIe adapter slot to server slot, run the following command:racadm setpciecfg assign [-c ] [i ]• For example, to assign PCIe slot 5 to server slot 2, run the following command.racadm setpciecfg assign -c PCIE.ChassisSlot.5 -i 2• To unassign a PCIe slot 3 from a server, run the following command:racadm setpciecfg unassign -c pcie.chassisslot.3PCIe Power Ride-ThroughNewly assigned PCIe cards in CMC VRTX must be discovered and initialized before a server node is powered on. The discovery andinitialization process involves the following:• Inventory and discovery of installed cards• Preparing a PCIe card for exposure to a server module• Preparing multiple cards for configuration by server BIOS• Initializing all cards prior to blade node power-onAll these processes require few seconds to complete which causes a delay in initialization of the PCIe cards. The PCIe Ride-throughfeature in CMC VRTX reduces this process cycle time. The PCIe Ride-through feature enables the following:184
