Example: Mapper report

Edit online

The mapper report displays the relation between the configured multipath devices and the corresponding SCSI- and FCP-devices.

The following example shows the output of the mapper report sorted in the order of multipath devices, remote ports and adapters. Multipath devices can be found in the sysfs under the directory /dev/mapper or displayed using the multipath utilities.

# ziorep_config -M -t
