nvme sanitize <device> [--no-dealloc | -d]
+              [--oipbp | -i]
+              [--owpass=<overwrite-pass-count> | -n <overwrite-pass-count>]
+              [--ause | -u]

DESCRIPTION

+
+

For the NVMe device given, sends a Sanitize command and +provides the result.

+

The <device> parameter is mandatory NVMe character device (ex: /dev/nvme0).

+

On success it returns 0, error code otherwise.

+
+
+
+

OPTIONS

+
+
+
+-d +
+
+--no-delloc +
+
+

+ No Deallocate After Sanitize: + If set, then the controller shall not deallocate any logical + blocks as a result of successfully completing the sanitize + operation. If cleared, then the controller should deallocate + logical blocks as a result of successfully completing the + sanitize operation. This bit shall be ignored if the Sanitize + Action field is set to 001b (i.e., Exit Failure Mode). +

+
+
+-i +
+
+--oipbp +
+
+

+ Overwrite Invert Pattern Between Passes: + If set, then the Overwrite Pattern shall be inverted between + passes. If cleared, then the overwrite pattern shall not be + inverted between passes. This bit shall be ignored unless the + Sanitize Action field is set to 011b (i.e., Overwrite). +

+
+
+-n <overwrite-pass-count> +
+
+--owpass=<overwrite-pass-count> +
+
+

+ Overwrite Pass Count: + This field specifies the number of overwrite passes (i.e., + how many times the media is to be overwritten) using the data + from the Overwrite Pattern field of this command. A value of 0 + specifies 16 overwrite passes. This field shall be ignored + unless the Sanitize Action field is set to 011b (i.e., Overwrite). +

+
+
+-u +
+
+--ause +
+
+

+ Allow Unrestricted Sanitize Exit: + If set, then the sanitize operation is performed in unrestricted + completion mode. If cleared then the sanitize operation is + performed in restricted completion mode. This bit shall be ignored + if the Sanitize Action field is set to 001b (i.e., Exit Failure Mode). +

+
+
+-a <action> +
+
+--sanact=<action> +
+
+

+ Sanitize Action: + 000b - Reserved + 001b - Exit Failure Mode + 010b - Start a Block Erase sanitize operation + 011b - Start an Overwrite sanitize operation + 100b - Start a Crypto Erase sanitize operation +

+
+
+-p <overwrite-pattern> +
+
+--ovrpat=<overwrite-pattern> +
+
+

+ Overwrite Pattern: + This field is ignored unless the Sanitize Action field in + Command Dword 10 is set to 011b (i.e., Overwrite). This field + specifies a 32-bit pattern that is used for the Overwrite + sanitize operation. +

+
+
+
+
+
+
