17 Replacing a Controller Canister and Related
Components
In this procedure, you will take the front subplate, the host interface card (HIC), the cache
memory DIMM, and the cache memory offload backup SD card out of the failed controller
canister and place them in the new controller canister before you install the new controller
canister.
You can determine whether you have a failed controller canister in two ways:
– The Recovery Guru directs you to replace a failed controller canister.
– You locate the failed controller canister by checking the Controller Service Action
Required LED.
Before you start to replace the controller canister, gather antistatic protection and a
replacement controller canister.
17.1 Removing a Controller Canister from the Controller-Drive Tray
1. If possible, use the storage management software to create, save, and print a new
storage array profile.
2. Did the Recovery Guru direct you to replace a failed controller canister?
– Yes
Go to step 3.
– No
Run the Recovery Guru to identify the failed component, and go to step 3.
3. Put on antistatic protection.
NOTICE!
This procedure refers to memory as cache memory DIMM and cache memory offload backup
SD card.
CAUTION!
Possible hardware damage
If you perform this procedure with the power turned on, the equipment might overheat if the
controller slot is left open for more than three minutes. To prevent the possibility of
overheating, you must insert the controller air blocker into the controller slot when servicing
the controller.
CAUTION!
Possible hardware damage
To prevent electrostatic discharge damage to the tray, use proper antistatic protection when
handling tray components.
NOTICE!
Possible extended outage
You must replace the controller with the power turned on to ensure auto-code
synchronization of the native controller firmware to the new controller, and to prevent the
possibility of an extended outage.
