NAME

ebsnvme-id —

NVMe disk identification tool for Amazon EC2

SYNOPSYS

ebsnvme-id [-b] [-m] [-s] [-u] [-v] ⟨device⟩

DESCRIPTION

The Amazon EC2 “Nitro” platform exposes disks to virtual machines via the NVM Express protocol. There are two types of disks so exposed: Elastic Block Store disks, which persist and can be detached and reattached to different virtual machines, and Instance Store disks (also known as “Ephemeral” disks), which exist only while the virual machine is running.

Amazon Linux provides a tool “ebsnvme-id” for identifying the attached Elastic Block Store disks; this ebsnvme-id is a re-implementation which also exposes some information about Instance Store disks.

The options are as follows:

-b: Print the “Linux device name” associated with the specified Elastic Block Store disk.
-m: Print the Model Number of the disk; this is either “Amazon Elastic Block Store” or “Amazon EC2 NVMe Instance Storage” depending on the type of disk.
-s: Print the Serial Number of the disk.
-u: Identical to the -b option.
-v: Print “Volume ID:” followed by the volume ID of the Elastic Block Store disk.

If no options are specified, ebsnvme-id operates as if invoked with the options -v -b.

If multiple option are specified, output is printed for each option, in the order -v [-b | -u] -m -s.
