Device BDEVs

Internally any logical drive is represented as BDEV block device. Therefore, drives of an attached device are reported in scope of BDEVs list. To get the list of all available devices attached to SPDK, use the command:

xnr_cli bdev show

Here is an example of 0000:06:0e.0n1 drive created during attaching 0000:06:0e.0 device and reported in scope of BDEVs list:
