Bringing System Components Down and Up
You can use the ftsmaint command to bring down and restart fault-tolerant components. After bringing up a
component, the system synchronizes and duplexes the corresponding component automatically.
When you use the bringDown command, the I/O module 1 stops.
#
/opt/ft/bin/ftsmaint bringDown 11
Completed bringDown on the device at path 11.
When you use the bringUp command, the I/O module 1 starts. The system automatically synchronizes I/O
module 1 with I/O module 0. The RAID array drives are updated and become mirrored, and the system should
resume duplex operation.
#
/opt/ft/bin/ftsmaint bringUp 11
Completed bringUp on the device at path 11.
