DESCRIPTION

+
+

Submits an NVMe Directive Receive admin command and returns the applicable +results. This may be the combination of directive type, and operation, as +well as number of requested resource if specific operation needs it.

+

The <device> parameter is mandatory and may be either the NVMe character +device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).

+

On success, the returned directive’s parameter structure (if applicable) is +returned in one of several ways depending on the option flags; the +structure may parsed by the program and printed in a readable format +if it is a known structure, displayed in hex, or the raw buffer may be +printed to stdout for another program to parse.

+
+
+
+

OPTIONS

+
+
+
+-n <nsid> +
+
+--namespace-id=<nsid> +

+-D <dtype> +
+
+--dir-type=<dtype> +
+
+

+ Directive type +

+
+
+-S <dspec> +

+--dir-spec=<dspec> +
+
+

+ Directive specific +

+
+
+-O <doper> +
+
+--dir-oper=<doper> +
+
+

+
+
+
+-l <data-len> +
+
+--data-len=<data-len> +
+
+

+ The data length for the buffer returned for this feature. Most + known features do not use this value. The exception is LBA + Range Type +

+
+
+-b +
+
+--raw-binary +
+
+

+ Print the raw receive buffer to stdout if the command returns + a structure. +

+
+
+-H +
+
+--human-readable +
+
+

+ Print the decoded receive buffer to stdout if the command returns + a structure. +

EXAMPLES

+
+
    +
  • +

    +Identify directive type supported : +

    +
    +
    +
    # nvme dir-receive /dev/nvme0 --dir-type 0 --dir-oper 1 --human-readable
    +
    +
    • +
  • +

    +Get stream directive parameters : +

    +
    +
    +
    # nvme dir-receive /dev/nvme0 --dir-type 1 --dir-oper 1 --human-readable
    +
    +
    • +
  • +

    +Allocate 3 streams for namespace 1 +

    +
    +
    +
    # nvme dir-receive /dev/nvme0n1 --dir-type 1 --dir-oper 3 --req-resource 3 --human-readable
    +
    +
    • +
  • +

    +Get streams directive status : +

    +
    +
    +
    # nvme dir-receive /dev/nvme0 --dir-type 1 --dir-oper 2 --human-readable
    +
    +

    It is probably a bad idea to not redirect stdout when using this mode.
