HP-UX Virtual Partitions Administrator's Guide (includes A.05.02)

Monitor and Shell Commands
Modes: Switching between nPars and vPars Modes (Integrity only)
Chapter 5
124
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.
• During a cold-install of the OE and vPars software, the following general steps could occur:
1. Boot and install the OE and vPars software as well as create the vPars database onto the intended
boot disk of a virtual partition.
2. Set the mode to vPars so that you can boot the nPartition into the vPars environment.
# vparenv -m vPars
3. Reboot the nPartition into the vPars environment and load the first virtual partition.
4. From the first virtual partition, use vparboot -I to install the OE and vPars software onto the
remaining boot disks of the remaining virtual partitions.
For detailed steps on how to do the installation, see “Installing vPars with Ignite-UX on Integrity” on
page 113.
• Suppose you have booted to the Monitor prompt but are unable to load any vPars databases. You can boot
the system into nPars (standalone) mode and attempt to look into the database without the Monitor
running. To do this:
1. Set the mode to nPars and reboot the nPartition:
MON> reboot nPars
2. During the nPartition bootup process, boot into standalone mode by booting the vmunix kernel
instead of the vPars Monitor:
Shell> fs0:
fs0:\> hpux.efi /stand/vmunix
# vparstatus -v -D /stand/vpdb
CAUTION
• When you set the mode to vPars for the first time on a system, you must use vparenv.
When a vPars database does not exist on a system, first boot into nPars (standalone) mode,
create the vPars database, and then use vparenv -m vPars to switch the mode to vPars.
If vparconfig reboot vPars is used and vparenv -m vPars has not previously been
executed on the system, it may not be possible to boot vPars.
• Changing the mode to vPars should be performed using vparenv instead of vparconfig
whenever possible.
NOTE
• When the system is at the EFI shell prompt in vPars mode, you can use either one of the
following commands to reset the nPartition:
— EFI_Shell> parconfig reset
— EFI_Shell> fsx:
fsx> vparconfig reboot vPars
