vPars Release Notes Revision History Revision History ❏ September 2005 Update Relative to the July 2005 documents, the following represents the changes shown in the September 2005 Update of the vPars documents. Note that this represents the changes in documentation; the July 2005 vPars A.04.01 software bits have not changed. • HP-UX Virtual Partitions Release Notes for vPars A.04.
vPars Release Notes What’s New in This Version of vPars (A.04.01) What’s New in This Version of vPars (A.04.01) This version includes: • OS Support vPars A.04.01 supports the HP-UX 11i v2 May 2005 Update or later. Note that there are now two streams for the vPars products: — vPars A.04.xx supports HP-UX 11i v2 May 2005 Update or later. — vPars A.03.xx supports HP-UX 11i v1. Each stream has its own product number: T1335BC T1335AC vPars A.04.xx for HP-UX 11i v2 vPars A.03.
vPars Release Notes What’s New in This Version of vPars (A.04.01) • 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.
vPars Release Notes What’s New in This Version of vPars (A.04.01) this UNIX shell command allows you to display or modify the HP-UX hardware path to EFI path mappings of bootable disks within the vPars database. See Chapter 2 of the Installing and Managing HP-UX Virtual Partitions document for information on using the EFI shell with vPars and the new -E option of the Monitor’s vparload command.
vPars Release Notes Switching Modes between vPars and nPars on Integrity Systems Switching Modes between vPars and nPars on Integrity Systems This section regarding modes and the new vPars commands for use on Integrity systems is included in Chapter 5 of the Installing and Managing HP-UX Virtual Partitions document but is duplicated here so that users are aware of this for vPars A.04.01 when using Integrity systems. Please see Chapter 2 for further information on using vPars A.04.
vPars Release Notes Switching Modes between vPars and nPars on Integrity Systems Note: Remember to issue a parconfig reset after setting the mode. parconfig nPars only sets the mode to nPars. You must issue the parconfig reset to reset the system so that it boots into nPars mode. Note: parconfig does not support switching to vPars mode. In other words, you can use parconfig to set the mode to nPars, but you cannot use parconfig to set the mode to vPars.
