SYNOPSIS
nvme-admin-passthru <device> [--opcode=<opcode> | -O <opcode>] [--flags=<flags> | -f <flags>] [-rsvd=<rsvd> | -R <rsvd>] [--namespace-id=<nsid> | -n <nsid>] [--cdw2=<cdw2> | -2 <cdw2>] [--cdw3=<cdw3> | -3 <cdw3>] [--cdw10=<cdw10> | -4 <cdw10>] [--cdw11=<cdw11> | -5 <cdw11>] [--cdw12=<cdw12> | -6 <cdw12>] [--cdw13=<cdw13> | -7 <cdw13>] [--cdw14=<cdw14> | -8 <cdw14>] [--cdw15=<cdw15> | -9 <cdw15>] [--data-len=<data-len> | -l <data-len>] [--metadata-len=<len> | -m <len>] [--input-file=<file> | -i <file>] [--read | -r] [--write | -w] [--timeout=<timeout> | -t <timeout>] [--show-command | -s] [--dry-run | -d] [--raw-binary | -b] [--prefill=<prefill> | -p <prefill>] [--latency | -T] [--output-format=<fmt> | -o <fmt>] [--verbose | -v]
DESCRIPTION
Submits an arbitrary NVMe admin command and returns the applicable results. This may be the simply the commands result and status, or may also include a buffer if the command returns one. This command does no interpretation of the opcodes or options.
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 structure (if applicable) may be returned in one of several ways depending on the option flags; the structure may printed by the program as a hex dump, or may be returned as a raw buffer printed to stdout for another program to parse.
OPTIONS
-O <opcode>, --opcode=<opcode>
-f <flags>, --flags=<flags>
-R <rsvd>, --rsvd=<rsvd>
-n <nsid>, --namespace-id=<nsid>

-r, --read, -w, --write
-i <file>, --input-file=<file>
-l <data-len>, --data-len=<data-len>
-m <data-len>, --metadata-len=<data-len>
-s, --show-cmd
-d, --dry-run
-b, --raw-binary
-p, --prefill
-T, --latency
-o <fmt>, --output-format=<fmt>
-v, --verbose
-t <timeout>, --timeout=<timeout>
