HP secure development lifecycle Starting with HP-UX 11i v3 March 2013 update release, HP secure development lifecycle provides the ability to authenticate HP-UX software. Software delivered through this release has been digitally signed using HP's private key. You can now verify the authenticity of the software before installing the products, delivered through this release. To verify the software signatures in signed depot, the following products must be installed on your system: • B.11.31.
1 Introduction Thank you for choosing HP-UX vPars and Integrity VM Version 6.3. This document includes an introduction to the product, information about product usage, support matrices, and references to additional documentation. The contents of this document are specific to this version of HP-UX vPars and Integrity VM. The latest documentation for HP-UX vPars and Integrity VM is available at http://www.hp.com/go/hpux-hpvm-docs.
2 Installing or upgrading to HP-UX vPars and Integrity VM V6.3 2.1 Virtualization Services Platform The physical server on which HP-UX vPars and Integrity VM is installed is referred to as a VSP (Virtualization Services Platform). vPars and Integrity VMs are subsequently created on these installations. The VSP is an HP-UX based system intended to provide virtualization services for vPars and Integrity VM guest instances that are hosted on it.
Ensure that the VSP has sufficient free memory, after all these overheads, for all guests that are expected to be operating from it. • I/O Adapters I/O adapters must be installed on the VSP to satisfy I/O requirements of all vPars and Integrity VMs which are expected to be operating from it. For more information about the I/O adapters supported with HP-UX vPars and Integrity VM V6.3, see Section 5.6.3.2 (page 37). For more information about sizing guidelines, see HP-UX vPars and Integrity VM V6.
NOTE: T8718AC must be obtained separately from the other bundles. 2.
3 New functionality and changes from earlier versions HP-UX vPars and Integrity VM V6.3 introduces several new features and enhancements. Some changes have been made to operational details from earlier versions. This chapter gives an overview of these. 3.1 New features and enhancements 3.1.1 Enhanced capability for emulated platform NVRAM (Non Volatile RAM) The hpvmnvram(1M) command has been enhanced to add network boot path to EFI boot menu of vPar and Integrity VM guests. 3.1.
Dependencies VSP must have WEB1310 release (B.11.31.1310) or later versions of the Emulex FCoE driver installed. • Online cleanup of failed, changed, or removed NPIV targets from within a vPar or Integrity VM guest is enabled. Dependencies ◦ VSP must be at March 2014 OE. If not, the ESCTL patch PHKL_43607 must be installed on the VSP. ◦ For NPIV vFCs created on Qlogic FC cards, the FCD driver version on the VSP must be March 2014 or later.
3.2 Changes from previous versions 3.2.1 Changes to operation of HPVM commands 3.2.1.1 hpvmmodify(1M) and vparmodify(1M) When hpvmmodify(1M) or vparmodify(1M) is used for adding I/O devices to running guests • Only one -a operation may be specified at a time. and • No other resource modification operations may be combined with the -a option. 3.2.1.2 hpvmstatus(1M) hpvmstatus(1M) has been enhanced to support new functionality introduced in this version.
4 Known problems, limitations, and workarounds This chapter provides information about problems, limitations, and workarounds known at the time HP-UX vPars and Integrity VM V6.3 was released. 4.1 CPU/vCPU 4.1.1 Increasing CPU entitlement on running Integrity VM guests may cause problems When the hpvmmodify(1M) is invoked on a running VM to increase its minimum entitlement (-e option), it may display a warning.
If loratune(1M) is run on active VSPs, it is necessary to stop all running vPars and VMs, stop and restart HP-UX vPars and Integrity VM to overcome potential problems. 4.3 Networking 4.3.1 Cannot remove a VLAN-based vNIC if the VLAN has been removed If a vPar is created with a vswitch based on a VLAN, and that VLAN has been removed, it is not possible to modify or remove a vNIC connected to that vswitch. Workaround Recreate the VLAN with nwmgr and restart the vswitch.
• Boot over a DIO device is not supported. Install or boot a vPar or VM over LAN must use AVIO devices. • No error recovery on HP Integrity Superdome 2 systems. Error recovery will not happen on DIO devices when a recoverable error occurs. The guest will be restarted. • Cannot dynamically delete DIO functions online. Such hpvmmodify operations have to be done when the vPar or VM is down.
4.3.5 DIO-capable functions might become inconsistent with information in vPar or VM device database Under certain conditions, the ownership of DIO-capable functions might become inconsistent with the information in the vPar or VM device database such that hpvmhwmgmt -p dio -l indicates that a DIO-capable function is owned by host. However, the hpvmdevmgmt -l gdev command indicates that it is assigned to the vPar or VM resource pool as a gdev.
# hpvmmigrate -P guest -h host2 -o . . . hpvmmigrate: Frozen phase (step 23) - progress 21% Target: (protocol low) header read timeout, 30 seconds Target: could not receive message header On the target VM Host machine, the syslog contains the following warning message: vmunix: HVSD: HPVM online migration warning: NPIV probe took too long, 79 seconds Workaround To solve this problem: 1. Verify that the probe time of each individual FC HBA is under 10 seconds. 2.
Workaround The interrupt balancing daemon is disabled by default. Do not enable the interrupt balancing daemon. 4.4.7 Online addition of DMP device as backing store is not supported Addition of DMP device on running guest fails with the following error: # hpvmmodify -p1 -a disk:avio_stor::disk:/dev/vx/rdmp/c513t16d5 Error: Online Addition of DMP device /dev/vx/rdmp/c513t16d5 is not supported. hpvmmodify: Unable to modify the vPar or VM.
4.6.3 Interrupt migration of vNICs during Online guest migration can result in network disconnectivity During Online migration of guest, if interrupt migration of vNIC is performed, there may be network disruption at the destination VSP. To avoid this issue, interrupt migration must not be performed during Online guest migration. 4.6.

that the Integrity VM guest was booted on and older than the current VSP, provided the Integrity VM guest has not been rebooted since the first migration. • For example, an Integrity VM guest booted on a VSP with HP-UX vPars and Integrity VM V6.1.5 may be forward migrated online to a VSP with V6.3 and then fallback migrated online to a VSP with V6.2 (and then again to V6.1.5 or even directly to V6.1.5) provided the Integrity VM guest has not been rebooted since the first migration from V6.1.5.
