Info

NOTE: In certain situations when using vPars with SAS disks on HP Integrity platforms, the vparstatus -v and setboot commands may show different boot disk paths in vPars mode. This is normal, and is due to the disks being scanned in a different sequence at boot time. You may see different boot disk paths for SAS disks reported by the vparstatus -v and setboot commands in vPars mode after booting into nPars mode and then booting back into vPars mode. For example: — A virtual partition is ignited from a SAS disk and booted in vPars mode, and the vparstatus -v command shows the boot disk path as A. — If the system is booted back to nPars mode, the boot path may change to B, which is different from A due to a different scan order. This would also change the boot path to B in the vPars database (/stand/vpdb). — After booting back to vPars mode, vparstatus -v for this virtual partition shows B as the boot path and setboot still shows A. Both boot paths (A and B) refer to the same SAS disk path. • vPars and Dynamic nPartition Operations Dynamic nPartitions operations cannot be performed to an nPartition that is running Virtual Partitions. For more information on dynamic nPartitions, see the HP-UX 11i v3 Dynamic nPartitions white paper at: http:// docs.hp.com/en/10907/dynamic_nPars_WP.pdf. • Support for vPars Configuration Based on Locally Optimized Reference Architecture (LORA) on Multi-Cell Integrity Systems LORA is a framework for increasing system performance by exploiting the locality domains in HP servers with Non-Uniform Memory Architecture (NUMA). LORA consists of configuration rules, tuning recommendations, HP-UX 11i v3 enhancements, and tools to support them. For more information on LORA, see “Planning Your Virtual Partitions for LORA Support” (page 65). Ordering vPars 26 Introduction For the latest information on ordering vPars, see the HP-UX Virtual Partitions Release Notes and the HP-UX Virtual Partitions Ordering and Configuration Guide. NOTE: The free product known as VPARSBASE is obsolete and is no longer available or supported.
2 How vPars and Its Components Work This chapter covers: • Partitioning Using vPars • vPars Monitor and vPars Partition Database • vPars Boot Sequence • EFI and Integrity Notes • Virtual Consoles and Logs • Security Partitioning Using vPars To understand how vPars works, compare it to a server not using vPars. Figure 2-1 shows a 4-way HP-UX server. Without vPars, all hardware resources are dedicated to one instance of HP-UX and the applications that are running on this one instance. Figure 2-1 Server without vPars Processor 0 SCSI 0/0 Host PCI Bridge 4 Processor 1 LAN 1/0 Memory 6 Processor 2 SCSI 0/0 6.0 6.0 Host PCI Bridge 5 Processor 3 Figure 2-2 shows the software stack where all applications run on top of the single OS instance: LAN 1/0 Partitioning Using vPars 27
