Installing/removing the FFx-RAID controller
module
V
CAUTION!
Observe the notes on safety and the information on electrostatic
sensitive device labeling in chapter "Important Notes" on page 7.
The FFx-RAID controller module can be installed and removed while the
subsystem is running provided that the configuration involved is a dual-active
configuration (two modules with dual-active configuration have been installed)
and the MultiPath software is active. If one FFx-RAID controller module is
removed, the second module automatically takes over its function (hot swap).
V
CAUTION!
As condition for a hot swap action the replaced FFx-RAID controller
modules (FFx-RAID controller) must have the same firmware version
and the same cache memory size.
