13 Replacing a Controller Canister in the Controller-Drive
Tray
Use this procedure to add a controller canister to the E2600 controller-drive tray or to replace
one that has failed. 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 in the controller-drive tray, gather antistatic
protection and a new controller canister.
When you install a new controller canister, you must remove the battery from the failed
controller canister, and install it in the new controller canister. This procedure includes that
task.
If you are changing your current configuration, you might need to replace these items:
– Small Form-factor Pluggable (SFP) transceivers.
– Host bus adapters.
– Cables – Both SAS and iSCSI use copper cables, and Fibre Channel supports copper
cables and fiber-optic cables.
13.1 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.
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.
NOTICE!
Possible loss of data access
If the controller that you are replacing manages any secure volumes, the new controller will
need the correct security key to manage those volumes. After you replace the controller and
restore power to the controller-drive tray, you can use SANtricity® ES Storage Manager to load
the key from the file in which it was saved. Be sure that such a file exists and that you know
the pass phrase required to install the security key before you replace the controller.
CAUTION!
Possible hardware damage
To prevent electrostatic discharge damage to the tray, use proper antistatic protection when
handling tray components.
NOTICE!
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.
