SET-DSSD-POWER-ST(1)

💖 NAME 💖

okay bestie, welcome to SET-DSSD-POWER-ST(1) from the NVMe Manual — this little icon is nvme-ocp-set-dssd-power-state-feature, aka Set DSSD Power State 💅

---

✨ SYNOPSIS ✨

nvme [<global-options>] ocp set-dssd-power-state-feature <device>
                        [--power-state=<fmt> | -p <fmt>] [--no-uuid | -n]
                        [--save | -s]

the synopsis also has --no-uuid/-n and --save/-s in the lineup, but the page doesn’t give them their own descriptions — no cap, I’m not inventing lore 🫶

---

🦋 DESCRIPTION 🦋

okay so for the NVMe device you give it, the official description says it “retrieves OCP DSSD Power state Feature” 👑 I’m quoting the page exactly, bestie — that’s the wording.

the <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0) or block device (ex: /dev/nvme0n1) 🌸

🚨 real talk: this will only work on OCP compliant devices supporting this feature. Results for any other device are undefined — do not test that on a device you love, fr fr 💀

on success it returns 0, error code otherwise 😌

---

🎀 OPTIONS 🎀

• -p <fmt>, --power-state=<fmt> — DSSD Power State to set in watts ⚡

---

🌈 GLOBAL OPTIONS 🌈

the following options are defined at the top-level nvme command and are available to this subcommand — main character global energy, iykyk ✨

• --dry-run — Print the command that would be executed, but do not actually execute it.
• --no-ioctl-probing — Disable probing for 64-bit IOCTL support.
• --no-retries — Disable retry logic on transient errors.
• -o <fmt>, --output-format=<fmt> — Set the reporting format to normal, tabular, 'json, or binary. Only one output format may be used at a time.
• --output-format-version=<version> — Select the output format version. Version 1 uses the original field naming, while version 2 (default) provides more consistent and script-friendly field names. Other versions are rejected.
• --quiet — Suppress informational messages. Errors are still reported, and --quiet cancels any --verbose for the library log level.
• --set-options=<key=value>[,<key=value>...] — Set libnvme library options for this invocation. Supported keys are force-4k, mi-probe-enabled, test-base-dir and test-sysfs-dir.
• --timeout=<ms> — Set the timeout for the command in milliseconds. infinite or -1 waits without a time limit (0xffffffff).
• -v, --verbose — Increase the level of detail in the output. May be specified multiple times to further increase verbosity.

these options can also be set as machine-wide defaults in nvme-cli.conf(5). A command-line flag always overrides the file 💖
