HSZ70 Single-Controller Configurations
Use the following steps and
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
2. Shut down “this controller” with the following command:
SHUTDOWN THIS_CONTROLLER
NOTE:
After the controller shuts down, the reset button

). 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 F

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 O
N
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:
•
O
N
, the ECB is fully charged.
•
F
LASHING
, 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 O
N
,
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
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?
•
•
No. The controller is “configured for
DUAL_REDUNDANCY with...” in transparent failover
mode. Proceed to
NOTE:
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:
•
O
N
, the ECB is fully charged.
•
F
LASHING
, 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.
