(2) Format the partition with FAT32.
mkdosfs –n LABEL –F 32 /dev/sdx1
LABEL: any volume label (up to 11 American Standard Code for
Information Interchange (ASCII) characters)

The size of disk partitions available is 1.9 TB or
less due to the restriction on the FAT32
supported by the EFI firmware.

Create a dump partition on a dedicated logical
unit (LU). Do not create any other partition on the
same LU.

With both Linux Tough Dump and a dump
partition, re-perform the command mkdosfs to
format the partition and set a volume label even if
the dump partition has already been formatted. If
a volume label is set with a command other than
the command above, the volume label may not
be correctly displayed in the EFI setup menu
described later.

Note that if the dump partition does not have
enough free space for the dump file, the part of
the dump file beyond the free space size is
discarded. Since dump files are not automatically
deleted, the user needs to properly delete some
for maintenance.

An area, where memory pages are the default
value (all: 0x0) at hardware memory dump, is not
saved in the dump file.

We recommend that you set a distinguishable
name on the volume label of a dump partition.

It is recommended that a dump partition be
connected to a path different from the boot path.

When there are multiple dump partitions or
multiple paths are connected to a dump partition,
a device that is recognized first at the EFI boot
will be a dump partition.
2 Create a file for identifying the dump partition.
You need to place a file on the root directory of the dump partition so that the
system can identify the dump partition. Only one partition among partitions
connected to the system is available as a dump partition. Create and place a
file for identification according to the table below.
File name DumpSignature.dat
