You have an x86-based system with mirrored boot drives (c1d0p0 and c2d0p0 ) . To enable the system to boot off of the disk (c2d0p0) which holds the secondary submirror when the primary boot disk (c1d0p0 ) 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.lst file and add the following information: root (hd1,0,a) kernel /boot/multibootmodule /boot/x86.miniroot-safe

B.
Use the kernel command to edit the boot entries in the GRUB main menu as follows:
root (hd1,0,a)
kernel /boot/multibootmodule /boot/x86.miniroot-safe

C.
Edit the bootenv.rc file and enter a value for the altbootpath parameter as follows:
altbootpath=c2d0p0 .

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.
