Managing PCIe Slots

By default, all slots are unmapped. You can do the following:
  • View the status of all PCIe Slots in the chassis.
  • Assign or remove an assigned PCIe slot from the servers.
Consider the following before assigning a PCIe slot to a server:
  • An empty PCIe slot cannot be assigned to a server that is turned on.
  • A PCIe slot with an adapter assigned to a server cannot be assigned to another server if the currently-assigned server (source) is turned on.
  • A PCIe slot with an adapter assigned to a server cannot be assigned to another (target) server which is turned on.
Consider the following before removing an assigned PCIe slot from a server:
  • If a PCIe slot is empty, a slot can be unassigned from a server, even if the server is turned on.
  • If a PCIe slot has adapter and it is not turned on, it can be unassigned from the server even if the server is on. This can occur when a slot is empty and the assigned server is turned on, and then a user inserts adapter in an empty slot.
Map or un-map the external PCIe adapter to blade:
  • Adapter is always powered on as a non-shared device. Henceforth, adapter is mapped to one server.
  • If an external PCIE slot is occupied by a shared adapter, the mapping prior to adapter which is inserted remains unchanged.
  • If an external PCIE slot is occupied by a shared adapter, PCIE slot may not map or unmap to or from a blade server. If a user attempts to map or unmap shared adapter an EEMI message is logged.
For more information about assigning and remove an assigned PCIe slot from the servers, see the Online Help.
  • NOTE:
    • Without a license, you can assign a maximum of four PCIe slots to full-height server, two to the upper slot and two to the extension slot, or two PCIe devices to a half-height server.
    • You can distinguish the properties of external PCIE slots with External Shared PERC 8 card devices from dedicated devices, these shared devices have different properties than dedicated devices.
    • In case of external SPERC, the status Shared is displayed. The options to map or unmap the External Shared PERC 8 card is not available.
