以下示例说明如何在非 primary 根域上管理直接 I/O 设备。
以下命令将生成一个错误，因为它试图从根域中删除仍处于活动状态的插槽：
primary# ldm remove-io /SYS/MB/PCIE7 ldg1 Dynamic I/O operations on PCIe slots are not supported. Use start-reconf command to trigger delayed reconfiguration and make I/O changes statically.
以下命令显示删除插槽的正确方法，即，首先在根域上启动延迟重新配置。
primary# ldm start-reconf ldg1 Initiating a delayed reconfiguration operation on the ldg1 domain. All configuration changes for other domains are disabled until the ldg1 domain reboots, at which time the new configuration for the ldg1 domain will also take effect. primary# ldm remove-io /SYS/MB/PCIE7 ldg1 ------------------------------------------------------------------------------ Notice: The ldg1 domain is in the process of a delayed reconfiguration. Any changes made to the ldg1 domain will only take effect after it reboots. ------------------------------------------------------------------------------ primary# ldm stop-domain -r ldg1
以下 ldm list-io 命令可验证 /SYS/MB/PCIE7 插槽是否不再位于根域中。
primary# ldm list-io NAME TYPE BUS DOMAIN STATUS ---- ---- --- ------ ------ pci_0 BUS pci_0 primary IOV pci_1 BUS pci_1 ldg1 IOV niu_0 NIU niu_0 primary niu_1 NIU niu_1 primary /SYS/MB/PCIE0 PCIE pci_0 primary OCC /SYS/MB/PCIE2 PCIE pci_0 primary OCC /SYS/MB/PCIE4 PCIE pci_0 primary OCC /SYS/MB/PCIE6 PCIE pci_0 primary EMP /SYS/MB/PCIE8 PCIE pci_0 primary EMP /SYS/MB/SASHBA PCIE pci_0 primary OCC /SYS/MB/NET0 PCIE pci_0 primary OCC /SYS/MB/PCIE1 PCIE pci_1 ldg1 OCC /SYS/MB/PCIE3 PCIE pci_1 ldg1 OCC /SYS/MB/PCIE5 PCIE pci_1 ldg1 OCC /SYS/MB/PCIE7 PCIE pci_1 OCC /SYS/MB/PCIE9 PCIE pci_1 ldg1 EMP /SYS/MB/NET2 PCIE pci_1 ldg1 OCC /SYS/MB/NET0/IOVNET.PF0 PF pci_0 primary /SYS/MB/NET0/IOVNET.PF1 PF pci_0 primary /SYS/MB/PCIE5/IOVNET.PF0 PF pci_1 ldg1 /SYS/MB/PCIE5/IOVNET.PF1 PF pci_1 ldg1 /SYS/MB/NET2/IOVNET.PF0 PF pci_1 ldg1 /SYS/MB/NET2/IOVNET.PF1 PF pci_1 ldg1
以下命令可将 /SYS/MB/PCIE7 插槽分配给 ldg2 域。ldm start 命令可启动 ldg2 域。
primary# ldm add-io /SYS/MB/PCIE7 ldg2 primary# ldm start ldg2 LDom ldg2 started
