HP-UX Virtual Partitions Release Notes (A.05.09)

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
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 command to reset
the system so 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.

This section provides a list of problems and limitations known to HP at the time of publication. If
workarounds are available, they are included. For information on specific defects, see the HP ITRC

• No support of agile addressing (extended hardware paths) for non-11.31
virtual partitions in mixed HP-UX 11i v1/v2/v3 vPars environments
Related Defect ID and Patch Number
QXCR1000764993
Applicable On
vPars A.04.xx on HP-UX 11i v2 (B.11.23), vPars A.03.xx on HP-UX 11i v1 (B.11.11)
Description
Any agile hardware path placed into the vPars database (/stand/vpdb) cannot be used to
boot HP-UX 11.11 or HP-UX 11.23 virtual partitions.
Symptoms
Virtual partition OS panic, of the following type:
panic: all VFS_MOUNTROOTs failed: NEED DRIVERS ?????
Workaround
Use legacy hardware paths when assigning boot paths to virtual partitions running HP-UX v2
(B.11.23) or HP-UX v1 (B.11.11).
• Configuring a virtual partition with a low amount of base memory can
result in a system hang or lead to slow system performance
Symptoms
System hang or slow system performance
