Identify device mapper entries for configured multipath devices by using the multipathd command. This helps link multipath device names to their underlying device mapper entries, aiding in monitoring, troubleshooting, and system administration tasks for accurate device identification.
Procedure
Display all device mapper devices:
# multipathd show maps format "%n %d" name sysfs mpathd dm-4 mpathb dm-3 mpatha dm-2 mpathh dm-9
