g. Repeat this entire procedure to replace the ECB for the
“other controller.”
All other supported enclosures
CAUTION:
Make sure that at least one ECB is connected to the
ECB Y-cable at all times during this procedure. Otherwise, cache
memory data is not protected and is subject to loss.
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.
a. Follow on-screen instructions concerning availability
and replacement questions for the ECB.
NOTE:
If an empty bay is not available, place the replacement ECB
on top of the enclosure or at the bottom of the rack.
b. Insert the replacement ECB into an appropriate bay or
near the ECB being removed.
c. Follow on-screen instructions to connect the ECB.
d. Disconnect the ECB Y-cable from the old ECB.
e. Press Enter/Return.
IMPORTANT:
Wait for FRUTIL to terminate.
f. For single ECB replacement:
1) Remove the old ECB and place the ECB in an
antistatic bag or on a grounded antistatic mat.
2) If the replacement ECB was not placed within an
available bay, install the ECB into the vacant bay of
the old ECB.
g. For dual ECB replacement, if the other cache module is
also to be connected to the new dual ECB, connect the
PC or terminal to the “other controller” maintenance
port.
The connected controller now becomes “this
controller.”
h. Repeat
through
as required.
i.
Disconnect the PC terminal from the controller
maintenance port.
HSJ80 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. Enter the following command to verify that system time is
set:
SHOW THIS_CONTROLLER FULL
3. If system time is not set or current, if desired, 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. Enter Y(es) to confirm the intent to replace the “this
controller” ECB.
6. 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
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.
a. Install a Battery Service Label on the replacement ECB
as described by the Compaq StorageWorks ECB Battery
Service Label Placement installation card.
b. 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.
Do not
remove the old ECB until the ECB charged LED on the
replacement ECB turns O
N
(see
1
).
The ECB expiration date and deep discharge history are
updated.
FRUTIL exits.
c. Disconnect the PC terminal from the controller
maintenance port.
d. Repeat this entire procedure to replace the ECB for the
“other controller,” if necessary.
