💖 NVME-OCP-DEVICE-C(1) — nvme-ocp-device-capability-log 💖

okay so this is the page from the NVMe Manual, and it is lowkey iconic if you're poking at OCP device capability logs. bestie, we're about to retrieve a whole log page. no cap. ✨

---

🎀 NAME 🎀

nvme-ocp-device-capability-log — retrieves the OCP Device Capability Log Page. that's the whole vibe. 💅

---

🦋 SYNOPSIS 🦋

nvme [<global-options>] ocp device-capability-log <device> [--no-uuid | -n]

---

🌸 DESCRIPTION 🌸

for the NVMe device you give it, this retrieves the OCP Device Capability Log Page. slay. 💖

the fields get decoded exactly the way the page’s Log Page Version defines them: FIPS 140 Validation and its status from version 2 (OCP 2.7). yes, that's the detail, keep it. 🎀

the <device> parameter is mandatory and can be either the NVMe character device (ex: /dev/nvme0) or block device (ex: /dev/nvme0n1). mandatory means mandatory, bestie. 🔥

⚠️ this will only work on OCP compliant devices supporting this feature. Results for any other device are undefined 😭 — that's the warning, don't ignore it.

on success it returns 0; error code otherwise. periodt. 💅

---

✨ OPTIONS ✨

• -n, --no-uuid — do not try to automatically detect UUID index for this command (default UUID index to 0). simple as that. 🫶

---

🌈 GLOBAL OPTIONS 🌈

the following options are defined at the top-level nvme command and are available to this subcommand:

• --dry-run — print the command that would be executed, but do not actually execute it. fake it till you make it, but safely. 💅
• --no-ioctl-probing — disable probing for 64-bit IOCTL support. 🎀
• --no-retries — disable retry logic on transient errors. no do-overs, got it. 💀
• -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. yes, that really is 'json with the apostrophe right there. copy it exactly if you're scripting. 🌸
• --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. so don't be messy. ✨
• --quiet — suppress informational messages. errors are still reported, and --quiet cancels any --verbose for the library log level. quiet mode, but make it useful. 🦋
• --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. iykyk. 💜
• --timeout=<ms> — set the timeout for the command in milliseconds. infinite or -1 waits without a time limit (0xffffffff). no clock anxiety. 🕰️
• -v, --verbose — increase the level of detail in the output. may be specified multiple times to further increase verbosity. more is more, bestie. 👑

these options can also be set as machine-wide defaults in nvme-cli.conf(5). a command-line flag always overrides the file. the file does not win. periodt. 💅

🍓 EXAMPLES 🍓

• this one has the program issue a device-capability-log command to retrieve the 0xC4 log page. 💖

# nvme ocp device-capability-log /dev/nvme0 -o normal
