Helpful Multipath commands

Other useful Multipath commands are described below.

MM Set failover priority <pathid> = <number> </insert>

This command sets the priority level for each path. The ID must be a valid path ID, and the number

must be a decimal integer value in the range 1-4,000,000, with 1 being the highest priority and

4,000,000 being the lowest priority. The default value of 0 (zero) indicates that there is no priority.

The /insert option will move the priorities on all paths that were equal or lower than <number>. For

example, if the paths had priorities of 1,2,3,4, and a new path is assigned a number 2 using the

/insert option, then the paths that were 2, 3, and 4 are moved to 3, 4, and 5, and the new path

assigned priority 2.

MM Set failover state <pathid> = <Up: Down> </setpath>

This command sets the state of the path. The ID must be a valid path ID. If the path is Up, it can be

taken offline, and will not be used to switch to. Another path will be selected. If the path is offline,

the path will be reactivated, if possible, and set to an Up state. The /setpath option will reselect the

highest priority path that is up.

MM Set failover path <pathid>

This command moves the selected path to the one specified by the path ID. The ID must be a valid

path that is up. This does not alter the priorities on the paths, and any reselection of the path may

cause the path to change. A later option will be added to reassign that path to the highest priority.

MM Restore failover path device_id

This command forces the device to reselect the highest priority path that is online. The device_id must

be a valid device ID.
