HP StorageWorks Replacing an HSG60 and HSG80 Cache Module Installation Instructions (EK-80CAH-IM. F01, March 2005)

Page 6
Note: The operational controller and the replacement controller
references that appear in this section may be reversed. The
operational controller is the one attached to the terminal or PC and
the one from which FRUTIL is executed.
Note: When replacing DIMMs, see Figure 3 on page 3.
Note: If you are installing a cache module after resolving a failed
cache state (refer to Table 14 through Table 16 of the “Controller
and Cache Replacement Troubleshooting” appendix in the HP
StorageWorks HSG60 and HSG80 Array Controller and Array
Controller Software Maintenance and Service Guide ), the
operational controller and the replacement controller references that
appear in this section may be reversed. The operational controller is
the one attached to the terminal or PC and the one from which
FRUTIL is executed.
H 1. For the replacement cache module, insert each DIMM
straight into the appropriate slot of the replacement
cache module (Figure 3 on page 3), ensuring that the
notches in the DIMM align with the tabs in the slot.
Use the following substeps to install the DIMMs:
H a. Press the DIMM gently into the slot until it is
seated at both ends.
H b. Ensure that the two retaining clips for the
DIMM are engaged.
H c. Make sure both ends of the DIMM are firmly
seated in the slot and both retaining clips engage
the DIMM.
H d. Repeat substep 1a through substep 1c above for
each DIMM.
 2. For the operational controller, complete the following
substeps:
 a. Connect a PC or terminal to the operational
controller, if not already connected.
Note: The controller connected to the PC or terminal becomes “this
controller.” The controller for the replacement cache module
becomes the “other controller.”
 b. Start FRUTIL by entering the following
command:
RUN FRUTIL
 c. Enter N(o) to the question about replacing the
cache battery.
 d. From the FRUTIL Main Menu, enter 2 for the
Install a controller or cache module option.
Figure 4: Install Options Screen
 e. Enter 3 to install the other cache module. The
Slot Designations screen is displayed.
 f. Enter Y(es) to confirm the intent to install the
slot x cache module.
FRUTIL quiesces all device ports, indicates a
time limit of 2 minutes to install the replacement
cache module, and begins displaying the time
remaining in 10-second intervals.
Caution: Wait for FRUTIL to quiesce the device
ports—indicated by an All device ports
quiesced message. Failure to allow the ports to quiesce
can result in data loss. Quiescing can take several minutes.
Note: A countdown timer allows you a total of 2 minutes to install
the cache module. After 2 minutes, “this controller” exits FRUTIL and
resumes operations. If this happens, return to step b, and then
proceed.
H 3. For the replacement cache module, complete the
following substeps:
H a. Carefully align and partially insert the cache
module in the appropriate guide rails.
Caution: Misalignment of the cache module in the guide
rails can damage the backplane.
Caution: If your cache module is in a BA370 enclosure,
you must disable the ECB. Failure to disable the ECB can
result in cache module damage. To disable the ECB,
complete the following steps:
1. Press the battery disable switch on the battery module.
2. Connect the ECB Y-cable to the cache module.
Refer to other ECB documentation for additional and
specific ECB details.
H b. After the message, Install the new
cache module in slot x within 2
minutes, is displayed, insert the replacement
cache module completely into the appropriate
bay, and engage the cache module retaining
levers.
Install Options:
1. Other controller and cache module
2. Other controller module
3. Other cache module
4. Exit
NOTE: OPTION 1 DISABLED (So: Do cache, then
controller.)
