Copying Software Images to Boot Devices with UNIX

To create a boot device with a UNIX computer:
1.
Description
Specifies the size of the config partition, in megabytes. The default value is 10 percent
of physical memory on the boot medium.
The config partition is mounted on /config. The configuration files are stored in
this partition.
This option causes the boot medium to be partitioned.
NOTE:
Specifies the size of the data partition, in megabytes. The default value is 0 MB.
The data partition is mounted on /data. This space is not used by the router, and
can be used for extra storage.
This option causes the boot medium to be partitioned.
NOTE:
Copies only default files that were loaded on the primary compact flash drive when it
was shipped from the factory, plus the rescue configuration if one has been set.
Once the boot medium is created with the factory option, it can operate in
NOTE:
only the primary compact flash drive slot.
Specifies the boot device the software is copied to:
compact-flash—Copies software to the primary compact flash drive.
removable-compact-flash—Copies software to the removable compact flash
drive. This option is available on J4300 and J6300 Services Routers only.
usb—Copies software to the device connected to the USB port.
You cannot copy software to the active boot device.
NOTE:
Partitions the medium. This option is usually necessary for boot devices that do not
have software already installed on them.
Specifies the size of the root partition, in megabytes. The default value is the boot
device's physical memory minus the config, data, and swap partitions.
The root partition is mounted on / and does not include configuration files.
This option causes the boot medium to be partitioned.
NOTE:
Specifies the size of the swap partition, in megabytes. The default value is one-third of
the physical memory on a boot medium larger than 128 MB, or 0 MB on a smaller
boot device.
The swap partition is used for swap files and software failure memory snapshots.
Software failure memory snapshots are saved to the boot medium only if it is
specified as the dump device. For information about the setting the dump device,
see "Configuring a Boot Device to Receive Software Failure Memory Snapshots" on
page 511.
This option causes the boot medium to be partitioned.
NOTE:
If you are copying a boot image to a compact flash drive, first plug the drive
into a PCMCIA adapter or USB card reader.
