HP-UX vPars and Integrity VM V6.1.5 Administrator Guide (5900-2295, April 2013)

4.1.2.2 Determine HP-UX 11i v3 memory and system disk requirements
Integrity VM V6.1.5 memory requirements vary depending on the number and size of virtual
machines supported by the Integrity VM server. When upgrading from an 11i v2 Integrity VM
server, use the following steps to determine the amount of memory required for the 11i v3 Integrity
VM server:
1. When your 11i v2 Integrity VM server is running at peak load, use the Integrity VM
hpvmstatus –s command to display the available memory.
2. If the available memory is less than 1 GB, then it is highly likely that your server requires
additional memory to run the same load with 11i v3 and Integrity VM V6.1.5. Before
upgrading, add the appropriate amount of memory to ensure that there is at least 1 GB of
memory available during peak loading.
NOTE: Different operating environments have different minimum memory requirements
4.1.2.3 Determine version requirements for HP-UX OE and vPars and Integrity VM
Of the HP-UX 11i v2 servers running Integrity VM, only those running Version 3.0 or Version 3.5
can be upgraded to the HP-UX 11i v3 Integrity VM V6.1.5 release. HP recommends that all virtual
machines (guests) be upgraded with Integrity VM Version 6.1.5 guest kits to take advantage of
performance enhancements and bug fixes. Guests that booted and ran on the 11i v2 Integrity VM
server will continue to function with equivalent or improved performance after the upgrade.
Existing guest configuration information, operating system software, and application data are not
affected when you upgrade Integrity VM. However, when you upgrade, also reinstall the guest kit
that is provided with Integrity VM. This operation requires you to reboot the guest. For more
information, see Section 8.3 (page 106).
When upgrading from a prior release, support for specific guests types or backing stores may
have been removed. For support information, see the HP-UX vPars and Integrity VM V6.1.5 Release
