Term Meaning
/qualifier This optional qualifier sets the value for R5 for
the bootloader. It is used to select a boot on the
disk, or a conversational boot.
The qualifier can be specified in either of the
following formats:


device, This optional term is the primary boot device.
If no device is specified, the system attempts to
boot the default device. You can set the default
boot device with the SET BOOT command.
second_device This optional term is the device the bootloader
tries to boot if the primary boot device fails.
Example:
This example shows the system performing a conversational boot
from DKA200. If the system cannot boot from DKA200, it tries a
conversational boot from DKA400.
