<Integer> MSD slot for format (Range: 0-1)
11503# format 1
The steps listed below are involved in this task.
Set the disk in slot two to work as a back up if the operating system in slot 0 fails.
11503# map secondary-boot 1 ?
<cr> Execute command
11503# show map
Primary-Boot: Slot 0 (mapped)
Secondary-Boot: Slot 1 (mapped)
Log: Slot 0 (unmapped)
Core: Slot 0 (unmapped)

11503# copy 0 boot-image sg0720104
Copying(/) /sgo720104/ ....
Setup the secondary boot information.
11503# conf t
11503(config-boot)# secondary boot-file sg0720104
