PA-RISC System Firmware Functions
• Supports only HP-UX
• Supports mixing of PA-RISC and Itanium cell boards in the same complex but in different
partitions
• Detects and rejects Itanium cell boards mixing in a partition with PA-RISC cell boards
• Support all system management tools available with sx1000 systems
• FRU isolation and event ID reporting as enabled by the hardware and manageability firmware
• Cell OLAD (COLAD) of cells with noninterleaved memory. PA-RISC I/O card OLAD support
requirements and design are the same as on sx1000 systems.
• Support for link level retry with self-healing for crossbar and I/O links
• Maximum of eight processor cores per cell board, based on NVM part size of 12 MB
• Supports two processors per CPU module
• Supports mixing of specific processor versions after they are identified as being compatible
by the program
• Dual-core configuration, deconfiguration. Support for 1, 2, and 4 GB DDR-II DIMMs
• Support for mixed DIMMs on a cell
• Support for nonuniform memory configurations within a partition and address parity
checking on DIMMs (no address ECC)
• Support for configuring and deconfiguring DIMMs in increments of two
• Enforcement of DIMM loading order
• PCI-X 2.0 (266 MHz) based I/O attach (PCI compatible)
• Support for all PCI-X and PCI cards supported by respective sx1000 systems
• Support for I/O slot doorbells and latches
• Elimination of Superdome core I/O card for Superdome/sx2000 console
Server Configurations
See the HP System Partitions Guide for information about proper configurations.
Basic Configuration Rules
