list failover devices device_id
|
This command lists all of the failover devices. It also lists all the paths associated with each device, their assigned priorities, and the path that is selected.
To list the paths associated with all the devices on the server, enter the command without specifying the device_id.
To list the paths associated with a given device, enter the command followed by the device_id. |
mm set failover priority pathid=number
|
This command sets the priority level for the selected path. The
pathid must be a valid path ID. The
number is the priority to set for the selected path. The number must be a decimal integer value between 1 and 4 million, with 1 being the highest priority and 4 million being the lowest priority.
|
mm set failover priority pathid=number /insert
|
The /insert option inserts the specified path with its specified priority. For example, if you have four existing paths that are assigned the priorities of 1, 2, 3, and 4, and you enter a new path followed by a number 2 and the /insert option, then the paths that were previously assigned to 2, 3, and 4 priority are bumped to priority 3, 4, and 5 in order to accommodate the new path that has been assigned priority 2. |
mm set failover state pathid=up /setpath
|
This command sets the state of the specified path to Up. The
pathid must be a valid path ID.
If the Up option is followed by the /setpath option, NSS automatically selects the highest priority path from among all the paths that are in the Up state, including the new path. |
mm set failover state pathid=down /setpath
|
This command enables you to designate a path to be in the Down state so you can perform preventative maintenance or reroute cables on a good, functional path. If the path is bad, NSS automatically moves the path to a Down state.
If the Down option is followed by the /setpath option, NSS automatically selects the highest priority path from among the other paths that are currently in the Up state. |
mm set failover path pathid
|
This command activates the selected path as
selected, which means it serves as the primary path. The
pathid must be a valid path that is currently in the Up state. The priority of a path remains static regardless of whether a path is considered up or down or whether a path is selected or not selected as the primary path.
|
mm restore failover path device_id
|
This command forces the device to reselect the highest priority path that is online. The
deviceid must be a valid device ID.
|
mm reset failover registry
|
This command resets the multipath settings in the operating system registry. |
