Priority of bootable devices
(1) Case when multiple bootable devices are connected
The devices are booted in descending order of the priority set in the Boot option. If the boot has failed, the
device that is the next one in the Priorities of the same device type is booted. When the boot of the device
that is the lowest in the Priorities of the same device type has failed, a device of the Priorities of the next
device type is booted.
For example, if there are two Priorities for each device type, the priority of the Boot Option and the Priorities
of each device type are as following:
- Priority of boot option and the Priorities of each device type ((1) to (8))
1. Boot Option #1 : CD/DVD
CD/DVD Priorities Boot Option #1 : CD/DVD device 1
…
(1)
CD/DVD Priorities Boot Option #2 : CD/DVD device 2
…
(2)
2. Boot Option #2 : Removable
Removable Priorities Boot Option #1 : Removable device 1
…
(3)
Removable Priorities Boot Option #2 : Removable device 2
…
(4)
3. Boot Option #3 : HDD
HDD Priorities Boot Option #1 : HDD device 1
…
(5)
HDD Priorities Boot Option #2 : HDD device 2
…
(6)
4. Boot Option #4 : Network
Network Priorities Boot Option #1 : Network device 1
…
(7)
Network Priorities Boot Option #2 : Network device 2
…
(8)
(2) Case when a bootable device is added
If a bootable device is newly connected, the added device is registered as the device that has the lowest
priority in the Priorities of each device type.
(3) Case when a bootable device is removed
If a bootable device is removed from the server, the subject device is deleted from the Priorities of each
device type.
(4) Case when “Load Setup Defaults” is executed
If "Load Setup Defaults" in the Save & Exit menu is executed, the settings of the Boot Options and the
Priorities of each device type are as the following:
a) Priority of Boot Options
1. Boot Option #1 : CD/DVD
2. Boot Option #2 : Removable
3. Boot Option #3 : HDD
4. Boot Option #4 : Network
b) Priorities in each Device Type
- The priority of non-USB devices (SATA device, RAID, etc.) is higher, and USB devices are
registered after them.
c) Bootable devices
- For disabled devices, the disabled state is released, and they are registered in the Priorities of
each device type again.
