nvme-intel-internal-log - Retrieve Intel device's internal log and save to file.
Contents
Description
For the NVMe device given, sends the Intel vendor unique device log request and saves the result to a
file.
The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a
namespace block device (ex: /dev/nvme0n1). If using the character device, the namespace id parameter is
mandatory.
This will only work on Intel devices supporting this feature which includes (but not limited to) all the
Intel DC P3xxx family of controllers. Results for any other device are undefined.
Examples
• Gets the nlog from the device and saves to default file:
# nvme intel internal-log /dev/nvme0 --namespace-id=1 --log=0
• Gets the event log from the device and saves to defined file:
# nvme intel internal-log /dev/nvme0 --namespace-id=1 --log=1 --output-file=MyAwesomeEventLog
