U Check if the device specified in the program environment is a multipathĭevice with usable paths. u Check if the device specified in the program environment should be a path ![]() The command itselfĭoesn't attempt to do I/O on the device. Whether or not I/O on this device is likely to succeed. C Check if a multipath device has usable paths. c Check if a block device should be a path in a multipath device. W Reset the WWIDs file to only include the current multipath devices. w Remove the WWID for the specified device from the WWIDs file. a Add the WWID for the specified device to the WWIDs file. Information (sysfs, the device mapper, path checkers. ll Show ("list") the current multipath topology from all available l Show ("list") the current multipath topology from informationįetched in sysfs and the device mapper. This operation isĭelegated to the multipathd daemon if it's running. F Flush (remove) all unused multipath device maps. This operation is delegated to the multipathd daemon if it's running. Using one of the following command line switches: -f Flush (remove) a multipath device map specified as parameter, if unused. The default operation mode is to detect and set up multipath mapsįrom the devices found in the system. WWIDs of devices present in the system, use e.g. WWID a World Wide Identifier matching a multipath map or its paths. This format can only be used for path devices. ID kernel device number specified by major:minor numbers, e.g. Multipath map, this selects the map or its paths, depending on the ![]() The node refers to an existing device mapper device representing a The expression mayīe in one of the following formats: device Multipath map or to its components ("paths").
