HP-UX Virtual Partitions Release Notes (A.04.01)

vPars Release Notes
What’s New in This Version of vPars (A.04.01)
Chapter 1 7
• Greater Flexibility
— full dynamic CPUs
The restriction of bound and unbound CPUs has been removed. In vPars A.04.01 all
CPUs, except for the one CPU on which the kernel of the virtual partition is booted
(the boot processor), can be migrated without any reboots. Further, all active CPUs in
an OS instance are capable of handling IO interrupts.
— support for cell local memory and cell local processors
You can now assign both memory and/or CPUs from a specific cell to a specific virtual
partition. For some workloads, this cell affinity for CPUs and memory can improve
performance.
See Chapter 6 of the Installing and Managing HP-UX Virtual Partitions for information
on assigning resources.
— Monitor prompt access
The Monitor prompt (MON>) is available whenever there is one available CPU.
See Chapter 5 of the Installing and Managing HP-UX Virtual Partitions for information
on the Monitor prompt.
• Easier Updating Process
You can now upgrade from a vPars A.03.xx PA-RISC environment to a vPars A.04.01
PA-RISC environment within the vPars environment, resulting in fewer reboots.
See Chapter 4 of the Installing and Managing HP-UX Virtual Partitions document for the
information on how to perform this update.
• new vPars commands
For use only on Integrity systems, vPars A.04.01 includes three new commands:
— vparenv
this UNIX shell command allows you to set the mode (vPars or nPars) for the next
reboot of the nPartition and to display and set the memory granularity size
— vparconfig
this EFI command allows you to set the mode (vPars or nPars) and forces a reboot of
the nPartition.
— vparefiutil
