IBM N Series User Manual

Attention: Do not turn off the storage system, disrupt the storage
connectivity, or remove target disks while sanitizing. If sanitizing is
interrupted during the formatting phase, the formatting phase must be
restarted and allowed to finish before the disks are sanitized and ready to
be returned to the spare pool.
If you need to abort the sanitization process, you can do so by using the
disk sanitize abort command. If the specified disks are undergoing the
formatting phase of sanitization, the abort will not occur until the disk
formatting phase is complete. At that time, Data ONTAP displays a
message telling you that the sanitization process was stopped.
-p pattern1 -p pattern2 -p pattern3 specifies a cycle of one to three
user-defined hex byte overwrite patterns that can be applied in succession
to the disks being sanitized. The default pattern is three passes, using 0x55
for the first pass, 0xaa for the second pass, and 0x3c for the third pass.
-r replaces a patterned overwrite with a random overwrite for any or all
of the passes.
-c cycle_count specifies the number of times the specified overwrite
patterns will be applied. The default value is one cycle. The maximum
value is seven cycles.
disk_list specifies a space-separated list of the IDs of the spare disks to be
sanitized.
3. If you want to check the status of the disk sanitization process, enter the
following command: disk sanitize status [disk_list]
4. After the sanitization process is complete, enter advanced privilege mode
by entering the following command: priv set advanced
5. Assign the disks to the appropriate storage system by entering the
following command: disk assign disk_list -o system_name
6. Return the disks to the spare pool by entering the following command:
disk unfail -s disk_list Data ONTAP designates the specified disks as
hot spares.
7. Return to administrative mode by entering the following command: priv
set
8. Optional: You can monitor the status of the sanitization process, or verify
that all disks were successfully sanitized, by using the
/etc/sanitized_disks and /etc/sanitization.log files.
Status for the sanitization process is written to the /etc/sanitization.log
file every 15 minutes.
The /etc/sanitized_disks file contains the serial numbers of all drives
that have been successfully sanitized.
