Preparing for the replacement
1.
If the controller enclosure or drive enclosure chassis
is operational, do the following to shutdown the
storage system:
a.
Stop all I/O to the storage system that includes
the failed chassis.
b.
Shutdown all array controllers in the system.
To shutdown a controller using the SMU, select
the array in the navigation tree and then select
Tools>Shutdown or Restart Controller. After the
controller is shut down, the blue OK to Remove
LED on the controller illuminates.
2.
Turn off power and cooling module switches (if
present).
3.
Make sure the cables are clearly labelled and then
disconnect the cables, including the power cords,
from the modules.
IMPORTANT:
Use caution when handling Fibre
Channel cables:
Touching the end of a Fibre Channel cable
either damages the cable or causes
performance problems, including intermittent
difficulties accessing the storage.
When a Fibre Channel cable or port is not
connected, install protective covers on the
ends of the cable or in the device port.
