HP E4510-48G Command Reference Manual page 1004

To execute the boot-loader command successfully, you must save the file for the next device
boot under the root directory of the storage media on a member device.
If the storage medium is on the master, you can specify the storage medium by giving its name,
such as flash; if the storage medium is on a slave, you can specify the storage medium by giving
its name and the member ID of the device, that is, in the format of slotslot-number#
StorageMediumName (slot-number represents the member ID of the salve), such as slot2#flash.
When you specify the boot file of the master, the file-url argument cannot contain the member ID
of the device, and slot-number should be specified as the member ID of the master; when you
specify the boot file of the slave, the file-url argument must contain the member ID (such as
slot2#flash:/test.bin), and slot-number should be specified as the member ID of the slave.
If you provide the keyword all, the file-url argument cannot contain a member ID, otherwise, the
execution of this command will fail; you must save the specified boot file on the storage media of
all member devices in the same filename, otherwise, member devices without this file will fail to be
reconfigured during the reboot.
The names of the files for the next boot of the master and slaves may be different, but the versions
of the files must be the same; otherwise, a slave will reboot by using the master's boot file and join
the stack again.

Examples
# Specify the main boot file for the master (the member ID is 1) for the next device boot as test.bin
(Make sure that the file test.bin is already saved on the storage medium of the master; otherwise, the
system prompts error and the execution of the commend fails).
<Sysname> boot-loader file test.bin slot 1 main
This command will set the boot file of the specified board. Continue? [Y/N]:y
The specified file will be used as the main boot file at the next reboot on slot 1!
# Specify the main boot file for the slave (the member ID is 2) for the next device boot as test.bin
(Make sure that the file test.bin is already saved on the storage medium of the slave; otherwise, the
system prompts error and the execution of the commend fails).
<Sysname> boot-loader file slot2#flash:/test.bin slot 2 main
This command will set the boot file of the specified board. Continue? [Y/N]:y
The specified file will be used as the main boot file at the next reboot on slot 2!
# Specify the main boot file for all member devices for the next device boot as test.bin (Make sure that
the file test.bin is already saved on the storage media of all the member devices; otherwise, the
system prompts error and the execution of the commend fails).
<Sysname> boot-loader file test.bin slot all main
This command will set the boot file of the specified board. Continue? [Y/N]:y
The specified file will be used as the main boot file at the next reboot on slot 1!
The specified file will be used as the main boot file at the next reboot on slot 2!
