Removing and replacing the expansion canister: 2145-12F or 2145-24F

You can replace a faulty SAN Volume Controller 2145-12F or 2145-24F expansion canister with a new one received from FRU stock.

Before you begin

Attention: Although many components are hot-swappable, they are intended to be used only when your system is not active (no I/O operations). If your system is powered on and processing I/O operations, go to the management GUI and follow the fix procedures. Initiating the replacement actions without the assistance of the fix procedures can result in loss of data or loss of access to data.

Do not remove an expansion canister unless you are directed to do so by a service procedure.

About this task

Procedure

Read the safety information to which Preparing to remove and replace parts refers.

Remove an expansion canister

In the management GUI, select Monitoring > System.
Right-click the expansion enclosure and click Identify to set the canister fault LED flashing.
Record which SAS cables are plugged into the specific ports of the expansion enclosure. The cables must be inserted back into the same ports after the replacement is complete; otherwise, the system cannot function properly.
Be careful when you are replacing the hardware components that are located in the back of the system. Do not inadvertently disturb or remove any cables that you are not instructed to remove.
Disconnect the SAS cables from the canister.
Open the two release levers, as shown in Figure 1. The canister moves out of the slot approximately 0.6 cm (0.25 inches).
Slide the canister out of the slot.

Replace an expansion canister

Open the release levers of the replacement canister.
Push the replacement canister into the slot until it stops.
Finish inserting the canister by closing both release levers so that both orange clasps snap into place. The canister is correctly installed when the rear face of the canister is flush with the rear edge of the enclosure. If the enclosure is powered on and the canister is correctly installed, the canister starts automatically.
Reattach each SAS cable into the port from which it was removed in step 5.
1. Ensure that the SAS cable connectors are inserted with the pull tab to the bottom of the connector; then, gently push the connector in until a slight click is felt or heard.
2. Verify that the connector is fully inserted by gently pulling on it (not on the tab). If the enclosure is powered on and the SAS connector is correctly inserted into the port, the green SAS link LED above the port lights up.
