NVME-SAMSUNG-VS-I(1) NVMe Manual NVME-SAMSUNG-VS-I(1) # [NAME](#NAME) nvme-samsung-vs-internal-log - Retrieve Samsung vendor specific internal firmware logs # [SYNOPSIS](#SYNOPSIS) ``` nvme [] samsung vs-internal-log [OPTIONS] ``` # [DESCRIPTION](#DESCRIPTION) Collect the internal firmware logs of a Samsung NVMe SSD and write them to disk. Host-initiated telemetry, controller-initiated telemetry and the vendor crash, memory and debug dumps are supported. Each dump is saved as its own file, so a single run usually produces several files. Use *--dump-type* to pick which dumps to collect; several types may be requested in a single run. This command will only work on Samsung devices supporting this feature. The *<device>* parameter is mandatory and may be either an NVMe character device (ex: /dev/nvme0) or an nvme block device (ex: /dev/nvme0n1). # [OPTIONS](#OPTIONS) -t <TYPE>, --dump-type=<TYPE> Comma-separated list of dump types to extract, given without spaces. The supported types are *host0* and *host1* for the host-initiated telemetry dump using Log Specific Parameter 0 and 1 respectively, *ctlr* for the controller-initiated telemetry dump, and *vendor* for the vendor dumps. When this option is omitted, every dump type except *host0* is extracted; *host0* is only collected when it is requested explicitly. -a <NUM>, --telemetry-data-area=<NUM> Telemetry data area to retrieve, 1 to 4. Defaults to 0, which retrieves every data area. Data area 4 is only extracted when the device reports that it supports it. This option only affects the telemetry dumps. -O <FILE>, --output-file=<FILE> Output file name, optionally preceded by a path (ex: *./path/name* or *./path1/path2/*). Any directory in the path that does not exist yet is created. When this option is omitted, the dumps are written to the current directory. -z, --compress Collect the dumps into a *temp\_samsung\_dumps* directory next to the output path and save them as a single compressed .tar.gz archive, removing that directory afterwards. The directory is created for this run alone, so the command fails if anything already sits at that path: one left behind by an interrupted run has to be removed before retrying. -H, --hide-progress Do not print the incremental progress of an extraction. Useful where the output is captured line by line and a carriage return does not overwrite, so that every update would be kept. The completion line of each dump is still printed. # [GLOBAL OPTIONS](#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. --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. --timeout=<ms> Set the timeout for the command in milliseconds. -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)](/man/os/nvme-cli/nvme-cli.conf.5). A command-line flag always overrides the file. # [EXAMPLES](#EXAMPLES) Extract the controller-initiated telemetry, the host-initiated telemetry using Log Specific Parameter 1 and the vendor dumps of the given device into the current directory. ``` # nvme samsung vs-internal-log /dev/nvme0 ``` Extract only the controller-initiated telemetry and the vendor dumps, naming both types in a single run. ``` # nvme samsung vs-internal-log /dev/nvme0 -t ctlr,vendor ``` Extract the host-initiated telemetry using Log Specific Parameter 0, which is not collected unless it is named explicitly, into ./dumps/, creating that directory if it does not exist. ``` # nvme samsung vs-internal-log /dev/nvme0 -t host0 -O ./dumps/ ``` Extract data area 2 of the host-initiated telemetry using Log Specific Parameter 1, store the result compressed and keep the output quiet. ``` # nvme samsung vs-internal-log /dev/nvme0 -t host1 -a 2 -z -H ``` # [NVME](#NVME) Part of the nvme-user suite 09/18/2026 NVMe --- Document: nvme-samsung-vs-internal-log(1) from nvme-cli 3.1-r1 (Chainguard OS) Source: https://github.com/linux-nvme/nvme-cli
