NOTE:
Considerations for removing controller modules:
•
In a dual-controller environment, you may hot-swap a single controller module in an operational enclosure, provided you first shut
down the faulty controller using theME Storage Manager or the CLI.
•
In a dual-controller environment—if replacing both controller modules—you must adhere to the instructions provided in
.
•
Do not remove a faulty module unless its replacement is on-hand. All modules must be in place when the system is in operation.
Illustrations in the controller module replacement procedures show rear panel views of the enclosure, and IOMs are properly aligned for
insertion into the IOM slots.
1
Verify that you have successfully shut down the controller module using the ME Storage Manager or the CLI.
2
Locate the enclosure whose UID LED (Ops panel on enclosure front left ear) is illuminated, and within the enclosure, locate the
controller module whose OK to Remove LED is blue (rear panel).
3
Disconnect any cables connected to the controller.
Label each cable to facilitate re-connection to the replacement IOM.
4
Grasp the module latch between the thumb and forefinger, and squeeze the flange and handle together to release the latch handle
from its docking member (detail No.1), and swing the latch out to release the IOM from its seated position (detail No.2) as shown in
