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:
, 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 O
N
,
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
through
.
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
through
, 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 using
the 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.
4. Start FRUTIL with the following command:
RUN FRUTIL
5. Continue this procedure as determined by the enclosure
type:
•
StorageWorks Model 2100 and 2200 enclosures
•
All other supported enclosures
StorageWorks Model 2100 and 2200 enclosures
a. Follow on-screen instructions to replace the ECB.
CAUTION:
Make sure to install the replacement ECB in a bay that
supports the same cache module as the current ECB being
removed (see
Remove the blank bezel from this replacement bay and reinstall
the blank bezel in the bay vacated by the current ECB. Failure to
reinstall the blank bezel might cause an over temperature
condition and damage the enclosure.
NOTE:
Install a Battery Service Label on the replacement ECB prior
to installing the ECB in the enclosure. This label indicates the
installation date (MM/YY) for the replacement ECB.
b. Install a Battery Service Label on the replacement ECB
as described by the Compaq StorageWorks ECB Battery
Service Label Placement installation card.
c. Remove the blank bezel from the appropriate bay and
install the replacement ECB.
IMPORTANT:
Do not
remove the old ECB until the ECB charged LED
on the replacement ECB turns O
N
(see
,
1
).
d. Remove the old ECB and install the blank bezel in this
bay.
e. Press Enter/Return.
The ECB expiration date and deep discharge history are
updated.
FRUTIL exits.
f. Disconnect the PC terminal from the controller
maintenance port.
