Operating System and Version Compatibility
This release is specific for HP-UX 11i v2 (B.11.23).
HP-UX 11i v2 (11.23) June 2007 or later is required for vPars A.04.05. For complete software,
hardware, and firmware requirements see the HP-UX Virtual Partitions Ordering and Configuration
Guide.
Hardware Requirements
The vPars A.04.05 release runs on HP 9000 servers and HP Integrity Servers with the HP-UX 11i
v2 (B.11.23) operating system.
Switching Modes between vPars and nPars on Integrity Systems
The following information on modes and using new vPars commands for Integrity systems is included
in Chapter 5 of the HP-UX Virtual Partitions Administrator’s Guide. It is duplicated here as a
reminder, in case you are using vPars A.04.xx on Integrity systems. See “Compatibility and
Installation Requirements” (page 5) for further information on using vPars A.04.xx on Integrity
systems, including other Integrity-only specifics.
Usage Scenarios
• If you are running HP-UX in nPars mode (standalone), use the following vPars command
to switch to vPars mode:
OS-Prompt> vparenv -m vPars /* sets the mode for the next nPartition reboot*/
OS-Prompt> reboot /* to reboot the system into vPars mode */
• If you are at the Monitor prompt, use the following Monitor command to switch to nPars
mode:
MON> reboot nPars /* sets the mode and reboots the system */
• If you are at the EFI shell prompt, use the following EFI utility to switch to either nPars or
vPars mode:
Shell:> fsN:
fsN:> vparconfig reboot nPars|vPars
Since vparconfig is not a built-in EFI shell command, you must go to the disk to execute
vparconfig. For example, to switch to vPars mode:
Shell:> fs0: /* go to the EFI partition of the disk */
fs0:> vparconfig reboot vPars /* sets the mode and reboots the system */
Note: vparconfig is an EFI utility which gets installed in the EFI partition during the
installation of the vPars product.
• If you are at the EFI shell prompt in vPars mode and you do not have vPars installed on
any of your disks, you can use the built-in EFI command parconfig to switch to nPars
mode:
Shell:> parconfig nPars
Shell:> parconfig reset
