--no-retries

Disable retry logic on transient errors.

Set the reporting format to *normal*, *tabular, 'json*, or *binary*. Only one output format may be used at a time.

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.
