When EFI to Hardware Path Mappings Are Not Up To Date
Following are some scenarios where you may need to perform additional actions if the EFI path to hardware
path mappings are not up to date in the vPars database:
• Creating an alternate vPars database while in vPars mode.
Problem:
If an alternate vPars database is created while in vPars mode and the Monitor is later booted using that
alternate database, then it may not be possible to boot some of the virtual partitions of the alternate
database if the EFI paths corresponding to those hardware paths are not present in the alternate
database.
Solutions:
• The virtual partitions that could not boot can be re-installed using vparboot -I:
vparboot -p
partition_name -I
• 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.
