Adding a PCI hot plug adapter The test VIOS has the following PCI Adapter configuration: # Slot Description Device(s) U787B.001.DNW0974-P1-C1 PCI-X capable, 64 bit, 133MHz slot ent0 U787B.001.DNW0974-P1-C2 PCI-X capable, 64 bit, 133MHz slot Empty U787B.001.DNW0974-P1-C3 PCI-X capable, 64 bit, 133MHz slot Empty U787B.001.DNW0974-P1-C4 PCI-X capable, 64 bit, 133MHz slot sisioa0 U787B.001.DNW0974-P1-C5 PCI-X capable, 64 bit, 133MHz slot pci5 lai0 For this VIOS, slots C2 and C3 are both empty hot-plug PCI adapter slots. Slots C1, C4, and C5 are also hot-plug adapter slots with an Ethernet card in C1, a SCSI RAID adapter in C4, and a graphics card in C5. To add an adapter, choose Add a PCI Hot Plug Adapter from the menu and a list of available slots will be presented, as in Example 5-14. Example 5-14 Add a PCI Hot Plug Adapter screen ¦ Add a PCI Hot Plug Adapter ¦ ¦ ¦ ¦ Move cursor to desired item and press Enter. Use arrow keys to scroll. ¦ ¦ ¦ ¦ # Slot Description Device(s) ¦ ¦ U787B.001.DNW0974-P1-C2 PCI-X capable, 64 bit, 133MHz slot Empty ¦ ¦ U787B.001.DNW0974-P1-C3 PCI-X capable, 64 bit, 133MHz slot Empty ¦ For this example, slot C2 is chosen and the output is displayed in Example 5-15. Example 5-15 Add a PCI Hot Plug Adapter to slot 2 Command: running stdout: yes stderr: no Before command completion, additional instructions may appear below. The visual indicator for the specified PCI slot has been set to the identify state. Press Enter to continue or enter x to exit. The rest of the adapter addition is performed exactly as in a stand-alone AIX 5L LPAR with the following tasks occurring: ► Indicator light for adapter placement flashes ► Adapter installation ► Finish adapter installation task using the diagmenu command 306 <strong>Advanced</strong> <strong>POWER</strong> <strong>Virtualization</strong> on IBM System p5
When the adapter has been added successfully, the diagmenu command will display the following: Add Operation Complete. After this step, the cfgdev command must be run to configure the device for the VIOS. Then, when a list of the available hot-plug adapters is selected in the diagmenu output, the new Fibre Channel card appears in slot C2: # Slot Description Device(s) U787B.001.DNW0974-P1-C1 PCI-X capable, 64 bit, 133MHz slot ent0 U787B.001.DNW0974-P1-C2 PCI-X capable, 64 bit, 133MHz slot fcs0 U787B.001.DNW0974-P1-C3 PCI-X capable, 64 bit, 133MHz slot Empty U787B.001.DNW0974-P1-C4 PCI-X capable, 64 bit, 133MHz slot sisioa0 U787B.001.DNW0974-P1-C5 PCI-X capable, 64 bit, 133MHz slot pci5 lai0 This Fibre Channel card is now ready to be attached to a SAN and have LUNs assigned to the VIOS for virtualization. Adding a SCSI hot swappable disk To add a hot swappable SCSI disk to the RAID enclosure of a VIOS, you need to use the diagmenu command again. Under the task selection, Hot Plug Tasks menu, choose the SCSI and SCSI RAID Hot Plug Manager menu. This gives the output shown in Example 5-16. Example 5-16 SCSI and SCSI RAID Hot Plug menu Make selection, use Enter to continue. List Hot Swap Enclosure Devices This selection lists all SCSI hot swap slots and their contents. Identify a Device Attached to a SCSI Hot Swap Enclosure Device This selection sets the Identify indication. Attach a Device to an SCSI Hot Swap Enclosure Device This selection sets the Add indication and prepares the slot for insertion of a device. Replace/Remove a Device Attached to an SCSI Hot Swap Enclosure Device This selection sets the Remove indication and prepares the device for removal. Configure Added/Replaced Devices This selection runs the configuration manager on the parent adapter where devices have been added or replaced. After selecting the Attach a Device to a SCSI Hot Swap Enclosure Device menu, you will be presented with a list of free slots in the RAID enclosure in which to plug the SCSI disk. Chapter 5.
