• The virtual partitions that could not boot can be booted using the Monitor command
vparload:
vparload -p partition_name -E disk_index
• Creating a virtual partition in vPars mode.
Problem:
If a virtual partition is created while in vPars mode, then it may not be possible to boot that
partition if the EFI path corresponding to the boot disk hardware path is not present in the
vPars database.
Solutions:
• The virtual partition can be re-installed using vparboot -I:
vparboot -p partition_name -I
• The virtual partition can be booted using the Monitor command vparload:
vparload -p partition_name -E disk_index
• An OS is installed not using vparboot -I and the database is created as a last step.
Problem:
If an OS is installed on one disk (for example, vpar1), the database (vpdb) is created on
vpar1, an OS is installed on vpar2 in nPars mode, vparenv is executed on vpar2 to change
the mode to vPars, and the Monitor is booted from the boot disk of vpar1, then it may not
be possible to boot vpar2.
Solutions:
• Boot from vpar1's boot disk into nPars mode and execute the following set of commands
to update the vPars database and change the mode:
vpar1# vparefiutil -u [-D /stand/vpdb]
vpar1# vparenv -m vPars
• Create the database (vpdb) on the last installed virtual partition and boot the Monitor
from it.
• MirrorDisk and EFI path.
Problem:
If the idisk command is executed on a disk during mirror disk creation, the EFI path of
the disk may change. It may not be possible to then boot from the new mirrored disk using
vparboot -B.
Solutions:
• After creating the mirror disk, set the mirror disk as alternate path using setboot.
# setboot -a mirror_disk_hw_path
•Execute the vparefiutil command on the new disk.
# vparefiutil -u [-H mirror_disk_hw_path]
• Booting from a recently added boot disk.
