The block-attach command seems to have succeeded.
It can be confirmed that sda2 is attached.

It can confirm the content if the mount is done.
# mount /dev/sda2 /mnt
# ls /mnt

If the mount is done, it comes to see it.
If it is recognized when starting, the block-attach command should not be used.
Then, it is necessary to define two disks by configuration file.
When starting, automatic mount will be able to be done if it set to /etc/fstab
as well as Native Linux.
