NAME¶

zbc_info - Get information on a ZBC or ZAC device

SYNOPSIS¶

zbc_info [options] device

DESCRIPTION¶

zbc_info is used to get information on a ZBC or ZAC device.

The device argument must be the pathname to the target device block device file (e.g., /dev/sdb), or to the target device SG node file (e.g., /dev/sg3). On old kernels lacking ZBC and ZAC support, only the device SG node file will be available. The device argument may also point to a regular block device file used for emulating a zoned block device. In this case, the zone information of the emulated state will be displayed only if the option -e is specified.

OPTIONS¶

The following options can be specified.

-h, --help

Display a usage help message and exit.

-v

Verbose mode (for debugging problems).

-e

Print information for an emulated device.
