General Information

The type of ECB used depends on the StorageWorks controller enclosure type.

WARNING: The ECB is a sealed, rechargeable, lead acid battery that must be recycled or disposed of properly according to local regulations or policies after replacement.
Do not incinerate the battery. Improper handling may cause personal injury. The ECB displays the following label:

Figure 1 and Figure 2 provide general information about the ECBs used with many StorageWorks controller enclosures.

1. Battery disable switch (SHUT OFF)
2. Status LED
3. ECB Y-cable

2. Status LED
3. ECB Y-cable
4. Faceplate and controls for second battery (dual ECB configuration only)

Figure 2: Dual ECB for dual-redundant controller configurations

StorageWorks Model 2100 and 2200 controller enclosures use a different type of ECB that does not require an ECB Y-cable (see Figure 3). These enclosures contain four ECB bays. Two bays support Cache A (bays A1 and A2) and two bays support Cache B (bays B1 and B2)—see this relationship in Figure 4.
NOTE: No more than two ECBs are supported within a StorageWorks Model 2100 or 2200 controller enclosure at any time—one for each array controller and cache set. Blanks must be installed in the remaining vacant ECB bays for controlling air flow.

1 B1 supports cache B
2 B2 supports cache B
3 A2 supports cache A
4 A1 supports cache A| 5 Controller A
6 Controller B
7 Cache A
8 Cache B

IMPORTANT: When replacing an ECB (see Figure 5), match the vacant ECB bay with the supported cache module. This bay will always be next to the failed ECB (see Figure 4).

HSZ70 Single-Controller Configurations
Use the following steps and Figure 1 or Figure 2 to replace an ECB:

1. Is the controller operating?
   • Yes. Connect a PC or terminal to the controller maintenance port supporting the old ECB cache module.
   • No. Go to step 3.

2.  Shut down “this controller” with the following command:
   SHUTDOWN THIS_CONTROLLER
   NOTE: After the controller shuts down, the reset button 1 and the first three port LEDs 2 turn ON (see Figure 6). This may take several minutes, depending on the amount of data that needs to be flushed from the cache module.
   Proceed only after the reset button stops FLASHING and remains ON.
   
   Figure 6: Controller reset button and first three port LEDs

3. Turn OFF subsystem power.
   NOTE: If an empty bay is not available, place the replacement ECB on top of the enclosure.

4. Insert the replacement ECB into an appropriate bay or near the ECB being removed.
   CAUTION: The ECB Y-cable has a 12-volt and a 5-volt pin.
   Improper handling or misalignment when connecting or disconnecting could cause these pins to contact ground, resulting in cache module damage.

5. Connect the open end of the ECB Y-cable to the replacement ECB.

6. Turn ON subsystem power.
   The controller automatically restarts.
   CAUTION: Do not disconnect the old ECB Y-cable until the  replacement ECB is fully charged. If the replacement ECB status LED is:
   • ON, the ECB is fully charged.
   • FLASHING, the ECB is charging.
   The subsystem can operate regardless of the old ECB status, but do not disconnect the old ECB until the replacement ECB is fully charged.

7. Once the replacement ECB status LED turns ON, disconnect the ECB Y-cable from the old ECB.

8. Remove the old ECB and place the ECB in an antistatic bag or on a grounded antistatic mat.

HSZ70 Dual-Redundant Controller Configurations

Use the following steps and Figure 1 or Figure 2 to replace an ECB:

1. Connect a PC or terminal to the maintenance port of the controller that has the operational ECB.
   The controller connected to the PC or terminal becomes“this controller”; the controller for the ECB being removed becomes the “other controller.”

2. Enter the following commands:
   CLEAR CLI SHOW THIS_CONTROLLER
   Is this controller “configured for MULTIBUS_FAILOVER with…” mode?
   • Yes . Go to step 4.
   • No. The controller is “configured for
   DUAL_REDUNDANCY with…” in transparent failover mode. Proceed to step 3.
   NOTE: Step 3 is a procedural workaround for controllers in transparent failover mode to make sure that the battery test in field replacement utility (FRUTIL) executes properly.

3.  Enter the following command:
   RESTART OTHER_CONTROLLER
   IMPORTANT: Wait until the following message is displayed before proceeding:
   “[DATE] [TIME]– Other controller restarted”

4.  Disable failover and take the controllers out of dual-redundant configuration with one of the following commands:
   SET NOFAILOVER
   or
   SET NOMULTIBUS_FAILOVER

5.  Start the FRUTIL with the following command:
   RUN FRUTIL

6. Enter 3 for the replace the “other controller” cache module battery option.

7.  Enter Y(es) to confirm the intent to replace the ECB.
   CAUTION: Do not disconnect the old ECB Y-cable until the replacement ECB is fully charged. If the replacement ECB status LED is:
   • ON, the ECB is fully charged.
   • FLASHING, the ECB is charging.
   The subsystem can operate regardless of the old ECB status, but do not disconnect the old ECB until the replacement ECB is fully charged.
   The ECB Y-cable has a 12-volt and a 5-volt pin. Improper handling or misalignment when connecting or disconnecting might cause these pins to contact ground, resulting in cache module damage.
   NOTE: If an empty bay is not available, place the replacement ECB on top of the rack (cabinet) or enclosure until the defective ECB is removed.

8. Insert the replacement ECB into an appropriate bay or near the ECB being removed.

9. Connect the open end of the ECB Y-cable to the replacement ECB and tighten the retaining screws.

10. Press Enter/Return.

11.  Restart the “other controller” with the following commands:
    CLEAR CLI
    RESTART OTHER_CONTROLLER
    IMPORTANT: Wait until the following message is displayed before proceeding:
    “[DATE] [TIME] Controllers misconfigured. Type SHOW_THIS_CONTROLLER”
    CAUTION: In step 12, entering the appropriate SET command is critical. Enabling an incorrect failover mode can cause loss of data and incur system down time.
    Verify the original failover configuration and use the appropriate SET command to restore this configuration.

12. Reestablish the dual-redundant configuration with one of the following commands:
    CLEAR CLI
    SET FAILOVER COPY=THIS_CONTROLLER
    or
    CLEAR CLI
    SET MULTIBUS_FAILOVER COPY=THIS_CONTROLLER
    This command copies the subsystem configuration from “this controller” to the “other controller.”
    IMPORTANT: Wait until the following message is displayed before proceeding:
    “[DATE] [TIME]– OTHER CONTROLLER RESTARTED”

13. Once the replacement ECB status LED turns ON, disconnect the ECB Y-cable from the old ECB.

14. For dual ECB replacement:
    a. If the “other controller” cache module will be connected to the replacement dual ECB, connect the PC or terminal to the “other controller” maintenance port.
    The connected controller now becomes “this controller.”
    b. Repeat step 2 through step 13.

15. Place the old ECB in an antistatic bag or on a grounded antistatic mat.

16.  Disconnect the PC or terminal from the controller maintenance port.

HSG60 and HSG80 Controller Configurations

Use the following steps and Figure 1 through Figure 5, as appropriate, to replace an ECB in single-controller and dual-redundant controller configurations using FRUTIL:

1. Connect a PC or terminal to the maintenance port of the controller that has the defective ECB.
   The controller connected to the PC or terminal becomes “this controller.”

2.  For StorageWorks Model 2100 and 2200 enclosures, enter the following command to verify that system time is set:
   SHOW THIS_CONTROLLER FULL

3. If system time is not set or current, enter current data usingthe following command:
   SET THIS_CONTROLLER
   TIME=dd-mmm-yyyy:hh:mm:ss
   IMPORTANT: An internal clock monitors the life of the ECB battery. This clock must be reset after replacing an ECB.

Hot-Pluggable Procedure for StorageWorks Model 2100 and 2200 Enclosures

For HSG60, HSG80, and HSJ80 controller configurations with FRUTIL support, follow the applicable controller procedure previously addressed. For a hot- pluggable ECB replacement, use the procedure in this section.
IMPORTANT: The pluggable procedure (used in the HSG60, HSG80, HSJ80, and HSZ80 controller sections) uses FRUTIL to update the ECB battery expiration date and deep discharge history.
The hot-pluggable procedure in this section replaces the ECB only and does not update ECB battery history data.
Use the following procedure to replace an ECB as a hot-pluggable device:

1. Using Figure 4, determine the specific bay to install the ECB.
   NOTE : Make sure this bay supports the same cache module (A or B) as the ECB being removed.

2. Press the release tab and pivot the lever downward on the replacement ECB.

3. Remove the blank panel from the appropriate vacant bay (A or B).

4. Align and insert the replacement ECB into the vacant bay until the lever engages the enclosure (see Figure 5).

5. Lift the lever upward until the lever locks.

6. If enclosure power is applied, verify that the LED displays a Charge Test state (see Figure 3 for LED locations and Table 1 for the proper display state).

7. Following ECB initialization, verify that the LEDs display either a Charging or Charged state (see Figure 3 for LED locations and Table 1 for the proper display state).

8.  Press the release tab on the old ECB and pivot the lever downward.

9. Remove the old ECB from the enclosure.

10. Install the blank panel in the vacant ECB bay.
