NEC Express5800/ft series maintenance

The ftsmaint command provides a control interface for managing your NEC Express5800/ft series
system's fault-tolerant functions. For information about using the ftsmaint command and using
device path enumeration to manage specific devices in your system, see the following sections:

ftsmaint Command
Component information
- ftsmaint ls path
This command displays the status of the hardware specified by the enumerated path.
Specifying a path displays a detailed status of the hardware at that path.
Omitting the path argument displays a less-detailed table of all fault-tolerant devices on the
system. See "Device Path Enumeration" for more information.
Output from ftsmaint ls path reflects what the ftSSS management software reports about the
state of a given component. Because of system latency, this may not reflect the immediate state
of the device.
To verify the actual state of the device, check the opstate of its LED.
Start/stop the component
- ftsmaint bringDown path
This command removes from service the CPU module, PCI module, or internal disk specified
by path. No other devices are supported. When you bring down a device, the effect on the
system is the same as physically removing it.
Caution:
When manually bringing down a component, it is possible that a whole CPU/IO
module will be taken out of service. Be careful to bring down a component only
when the system is fully duplexed.
- ftsmaint bringUp path
This command brings into service the CPU module, PCI module, or internal disk
specified by path. No other devices are supported.
Note:
Running the ftsmaint bringUp command on a CPU module degrades system
performance and halts network communications for up to a minute.
