Removal and Replacement Shutting Down nPartitions and Powering Off Hardware Components Shutting Down nPartitions and Powering Off Hardware Components When you remove and replace hardware you may need to shut down one or more nPartitions on the server. In some cases you also will need to power off hardware components as part of the remove and replace procedure. This section gives details on how to ensure that an nPartition is properly shut down, and it also describes how to power off (and power on) hardware components. Shutting Down an nPartition This procedure is for checking an nPartition's boot status and, if needed, shutting down HP-UX on the nPartition. Step 1. Advise the customer that the system (one or more nPartitions) must be shut down for repairs. Ensure that the customer has a current backup, and inform the customer of the anticipated downtime. Step 2. Login to the server's service processor (MP). Step 3. Use the Virtual Front Panel (VFP) to view the current state of the nPartition that you will shut down. From the MP Main menu, enter VFP to access the Virtual Front Panel menu, and select the nPartition whose boot state you want to view. Type Control-b (^B) to exit the VFP display. • If an nPartition has booted HP-UX, or if it is in the process of launching HP-UX, you must shut down HP-UX on the nPartition. When HP-UX is running on an nPar, its VFP displays "HP-UX heartbeat" with a blinking asterisk (*) to indicate its interactivity. In this case, proceed with the next step. • If the nPartition is at its Boot Console Handler (BCH) interface, then HP-UX has already been shut down. • If the nPartition currently is booting, then you should wait for it to reach the BCH interface and-if necessary-interrupt auto-boot when you see the "Attempting to boot" and "To discontinue, press any key within 10 seconds" messages. If the nPartition is at the BCH menu interface then HP-UX is shut down. Otherwise, proceed with the next step to shut down HP-UX. Step 4. From the MP Main menu, enter CO and select the console for the nPartition you plan to shut down. You should have access to the HP-UX login prompt (or command line) when using the nPartition's console. If you have no interactivity at the console, HP-UX may be halted or hung. Step 5. At the nPartition's console, login to HP-UX and shut down the operating system. After making arrangements with the customer, issue the shutdown command to shut down and halt HP-UX on the nPartition. 58 Chapter 4
