You have an x86-based system with mirrored boot drives (cid0p0 and c2d0p0). To enable the
system to boot off of the disk (c2d0p0) which holds the secondary submirror when the primary
boot disk (cid0p0 ) fails, you need to configure the system to see c2d0p0 as the alternate boot
device. Which answer describes the procedure used to configure the alternate boot device?
A.
Edit the /boot/grub/menu. 1st file and add the following information:
root (hdl,0,a)
kerne1 /boot/multi boot
module /boot/s86.miniroot—safe
B.
Edit the bootenv. re file and enter a value for the altbootpath parameter as follows:
altbootpath=c2d0p0 .
C.
Use the kernel command to edit the boot entries in the GRUB main menu as follows:
root (hdl,0,a)
kerne1 /boot/multiiboot
module /boot/x86.miniroot—safe
D.
Press the space bar when the GRUB menu is visible during the boot process to edit the list of
commands, and enter the command to boot from the alternate disk drive.
