ATA
SANITIZE
command. Therefore, you can use the Ubuntu OS command
hdparm
to sanitize
the DGX Station SSDs.
Ensure that you are running an Ubuntu Desktop LiveCD session on the DGX Station as
explained in
Running an Ubuntu Desktop LiveCD Session on the DGX Station
This task requires
sudo
privileges.
Perform this task in a text-only TTY session from the Ubuntu Desktop LiveCD session.
1. Obtain the device IDs of the SSDs by searching for the word
disk
in the output from the
lsblk (http://manpages.ubuntu.com/manpages/bionic/man8/lsblk.8.html)
$
lsblk | grep disk
You can identify the SSDs from their size, which is much larger than the size of any
removable media that might be connected to the DGX Station, such as the USB flash drive
from which you are running the Ubuntu Desktop LiveCD session.
In the following example, the device IDs of the SSDs are
sda
,
sdb
,
sdc
, and
sdd
. The device
ID
sde
is the device ID of a USB flash drive.
$
lsblk | grep disk
sda 8:0 0 1.8T 0 disk
sdb 8:16 0 1.8T 0 disk
sdc 8:32 0 1.8T 0 disk
sdd 8:48 0 1.8T 0 disk
sde 8:64 1 1.9G 0 disk /cdrom
2. Confirm that all the SSDs support the ATA
SANITIZE
command.
For each SSD, run the
hdparm
command with the
-I
option.
$
sudo hdparm -I /dev/
device-id
| grep SANIT
device-id
The device ID of the SSD, for example,
sdc
.
This example confirms that SSD
sdc
supports the ATA
SANITIZE
command. The asterisk
(
*
) in the output from the
hdparm
command denotes support.
$
sudo hdparm -I /dev/sdc | grep SANIT
* SANITIZE_ANTIFREEZE_LOCK_EXT command
* SANITIZE feature set
3. Issue the ATA
SANITIZE
command to all the SSDs.
For each SSD, run the
hdparm
command with the
--yes-i-know-what-i-am-doing
and
--sanitize-block-erase
options.
#
sudo hdparm \
--yes-i-know-what-i-am-doing \
--sanitize-block-erase /dev/
device-id
device-id
The device ID of the SSD, for example,
sdc
.
This example issues the ATA
SANITIZE
command to SSD
sdc
.
$
sudo hdparm \
--yes-i-know-what-i-am-doing \
--sanitize-block-erase /dev/sdc
/dev/sdc:
Issuing SANITIZE_BLOCK_ERASE command
Operation started in background
You may use `--sanitize-status` to check progress
Sanitizing a single SSD takes several minutes.
