If you add a boot disk at a known hardware path, it may not be possible to immediately boot
from this new disk.
Solution:
• If the EFI signature of the disk is known, the vparload -E command can be used to
boot from the disk.
CAUTION It is recommended to use the documented procedure of using vparboot -I to create the virtual
partitions so that users do not have to use vparload -E. For information on the Monitor
command vparload, see the Monitor manpage vpmon (5).
vparload -E works in a trial and error fashion, meaning you may have to serially attempt
different disk indices. If there are multiple boot disks belonging to a virtual partition, booting
with vparload -E is easier if the EFI signature of the desired boot disk is known.
Attempting to boot from a incorrect boot disk may result in an ungraceful shutdown or early
panic with the message "root already mounted" if another OS instance is already booted
from that boot disk.
