Configuring NVMe PCIe Resource PaddingConfiguring NVMe PCIe Resource Padding
Use the NVMe PCIe Resource Padding option to configure PCIe resources to support PCIe hot-add for NVMe drives.
ProcedureProcedure
1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > PCIe Device Configuration
Options > NVMe PCIe Resource Padding .
2. Select a setting.
Normal—When this option is selected, PCIe resources are only allocated to devices installed at boot time, and PCIe hot-add is
not supported.
Medium—When this option is selected, additional PCIe resources are allocated for each PCIe Root Port, which might enable a
PCIe hot-add event to work without requiring a system reboot to enumerate the device.
High—When this option is selected, a maximum amount of PCIe resources are set aside to allow for the best chance of
supporting a PCIe hot-add event.
3. Save your setting.
