Shutting Down All Virtual Partitions The only times you need to shutdown all of the virtual partitions within a hard partition is when a hardware problem or nPartition modification requires the nPartition to be down. To gracefully shutdown all the virtual partitions in an nPartition, run the following command: poweroff partition OVERRIDE To ungracefully shutdown all the virtual partitions in an nPartition, run the following command: poweroff partition OVERRIDE FORCE Managing: Removing a Virtual Partition To remove a virtual partition, use vparremove. vparremove purges the virtual partition from the parspec. Any resources dedicated to the virtual partition are now free to allocate to a different virtual partition. You need to shutdown the virtual partition before attempting removal. If the target virtual partition is running, vparremove will fail. Example To remove a virtual partition named vPar0001: 1. Login to the OA. 2. The partition must be in the Down state. vparstatus -N nPar0001 -p vPar0001 The virtual partition, if running, can be shutdown from the OA using poweroff command, or from OS by running the following commands: # vparstatus -N 1 # shutdown -h 3. After the virtual partition is in the down state, remove the virtual partition vPar0001: vparremove -N nPar0001 -p vPar0001 -f Unintentional use of this command has serious consequences; therefore the user is required to confirm the operation with the -f (force) option. Boot options management for partitions On HP Superdome 2 servers, a virtual partition is presented much like a finer grained nPartition. Each virtual partition has its own EFI shell. This means that an OS in a virtual partition can be booted from the EFI shell just like an nPartition. Standard EFI/loader/OS mechanisms can be used to set boot disks, specify kernel paths and kernel boot options for a vPar. NOTE: Consequently, there is no support for specifying boot disk, kernel boot path or kernel boot options in the vPar commands. OS commands like setboot now directly operate on the stable storage of the virtual partition instead of updating the vpdb (which used to be the case on earlier platforms). For example, if you are logged into virtual partition Oslo2 and execute the command: Oslo2# Oslo2# setboot -b on this would set the "autoboot" attribute to "ON" in the stable storage of virtual partition Oslo2. On Superdome 2 platforms, when running in a vPar OS, the following options of the setboot command may be used to alter boot settings on a virtual partition: -p : To set the primary boot path 92 Managing and Booting Virtual Partitions
