Returning A Failed Or New Canister To Normal Operating Mode - Silicon Graphics TP9400 RAID Owner's Manual

4: Controller Enclosure Component Replacement Procedures

Returning a Failed or New Canister to Normal Operating Mode

52
When you replace a failed controller, the storage management software (TPSSM7)
will automatically synchronize the firmware between the existing controller and the
new controller. If not, you must download new firmware to the replaced controller.
See the storage management software for more information.
6. Check the controller canister that you just installed by doing the following:
a. Check the controller canister indicators. The green Controller Power indicator
should be on and the amber Controller Fault indicator should be off (Figure 3-5
on page 37). If so, go to step 7. If the Controller Power indicator remains off or
the Controller Fault indicator is on after a few seconds, make sure that the
controller canister is locked into place. If the Controller Fault indicator remains
on, go to step b.
b. Use the storage management software (TPSSM7) to check the status of both
controllers. If applicable, perform the recovery procedures required by the
software. If this corrects the fault and the controller enclosure is operating
without error, go to step 7. If not, go to step c.
c. Try replacing the controller. Check for new error messages or controller faults.
Replace the controller canister with a new one if necessary. If this corrects the
fault and the controller enclosure is operating without error, go to Go to step 7.
If not, go to step d.
d. If the previous steps do not correct the problem, call the customer support
representative (see "Product Support" on page xix).
7. Replace the front cover on the controller enclosure (Figure 4-1 on page 50).
Important: After replacing a controller, you must return the system to its normal
operating mode according to the steps outlined below. The procedure is to be used after
replacing a failed storage controller canister in the dual-active TP9400.
1. Bring up the TPSSM7 Storage Manager window.
2. Left-click the replaced storage controller.
3. Right-click the replaced controller to display the pop-up menu.
4. Select Change Mode on the pop-up menu.
