Boot disk configuration

After verifying there are two disks in the boot list...

# bootlist -m normal -o

... verify and create a boot image on the second mirrored boot disk:

# bosboot -vd hdisk1 && bosboot -ad hdisk1

How to know on which disk the OS has booted (bootblock used and kernel loaded):

# bootinfo -b

How to know on which mode the OS has booted (kernel in 32-bit or 64-bit):

# bootinfo -K

If there is some problem booting on one disk, be sure that the corresponding raw device are the same device as ipldevice:

# bootinfo -b
# ls -ilF /dev/ipldevice /dev/rhdisk0

# mount
