x86: Initiating a Fast Reboot to a Specific UFS Boot Disk or a ZFS Root Pool

You can specify an alternate UFS boot disk in any of the following ways:

# reboot -f -- '/dev/dsk/c0t0s3'
# reboot -f -- '/dev/dsk/c0t0s3 -k'
# reboot -f -- '/dev/dsk/c0t0s3
# /platform/i86pc/mykernel/amd64/unix -k'

You can specify a ZFS root dataset in any of the following ways:

# reboot -f -- 'rpool/zfsbe1'
# reboot -f -- 'rpool/zfsbe2 -k'
# reboot -f -- 'rpool/zfsbe3 /platform/i86pc/mykernel/amd64/unix -k'

When rebooting to a different root (/) disk or root dataset by using a mount point or a boot environment, be aware that no transient menu entry is added to the menu.lst file.
