Basics of nPartition Creation Creating an nPartition involves using an nPartition administration tool to assign one or more cells in a complex to the new nPartition. At the time an nPartition is created you also can optionally specify various configuration options for the nPartition, such as its name, cell use-on-next-boot values, and other details. After an nPartition is created you can modify the nPartition, as described in "Basics of nPartition Modification" (page 30). For detailed procedures see Chapter 6 (page 165). NOTE: When creating an nPartition, follow the HP nPartition requirements and guidelines. HP recommends only specific sets of nPartition configurations. For nPartition configuration requirements and recommendations, see Chapter 3 (page 61). The method you choose for creating an nPartition can depend on whether you are creating the first nPartition in a complex, creating a "Genesis Partition" for a complex, or creating an additional nPartition in a complex that already has one or more nPartitions defined. • Creating the First nPartition in a Server Complex To create the first nPartition in a complex you can do so either by creating a Genesis Partition or by using an nPartition administration tool to remotely manage the complex using IPMI over LAN. - All cell-based servers support creating a Genesis Partition. See "Creating a Genesis Partition for a Server Complex" (page 29). - Only cell-based servers based on the HP sx1000 or sx2000 chipset support remote administration using IPMI over LAN. From a system with the Enhanced nPartition Commands, use the parcreate command -g... -h... set of options. Or from Partition Manager Version 2.0 use the Switch Complexes dialog to connect to the complex and use the nPartition→Create nPartition action. For remote administration details see "Remote and Local Management of nPartitions" (page 41). • Creating a Genesis Partition for a Server Complex Creating a Genesis Partition involves the service processor (MP or GSP) CC command to specify that an initial, one-cell nPartition be created within the server complex. To create a Genesis Partition, the complex either must have no nPartitions defined, or all nPartitions must be shutdown for reconfig (inactive). For details see "Genesis Partition" (page 30). • Creating Additional nPartitions in a Server Complex You can use either of two methods to create additional nPartitions in a complex where one or more nPartitions already are defined: either use parcreate or Partition Manager from an nPartition running in the complex, or use the remote administration feature of those tools running on a system outside the complex. For a detailed procedure see "Creating a New nPartition" (page 172). - Creating a New nPartition Locally - To create a new nPartition in the same complex where parcreate or Partition Manager is running at least one nPartition must be booted with an operating system that has the nPartition tools installed. Login to HP-UX on the nPartition and issue the parcreate command, or access Partition Manager running on the nPartition and use its Create nPartition action. - Creating a New nPartition Remotely - To remotely create a new nPartition in a complex, do so either by using the Enhanced nPartition Commands version of parcreate, or by using Partition Manager Version 2.0. Only cell-based servers based on the HP sx1000 or sx2000 chipset support remote administration. Both parcreate and Partition Manager support two methods of remote administration: WBEM and IPMI over LAN. For remote administration using WBEM the tool remotely accesses a booted operating system running on an nPartition in the target complex (for Overview of Managing nPartitions 29
