About these instructions

This document contains instructions for replacing or upgrading

dual inline memory modules (DIMMs) in a cache module for

HP StorageWorks HSG60 and HSG80 subsystems.

Note: For instructions on upgrading a single-controller

configuration to a dual-redundant controller configuration, refer to

the appropriate array controller user guide or maintenance and

service guide.

Procedures in these instructions include:

■ Replacing an HSG60 and HSG80 DIMM in

single-controller configurations, page 2

■ Replacing an HSG60 and HSG80 DIMM in dual-redundant

controller configurations, page 4

General information

Figure 1, Figure 2, and Figure 3 (on page 2) provide general

information about the cache module.

Figure 1: Cache module

Note: In Figure 2, the environmental monitoring unit (EMU) and

power verification assembly (PVA) modules only exist in HP

StorageWorks BA370 enclosures. The controller and cache module

locations are consistent with other HP StorageWorks controller

enclosures.

Caution: Static electricity can easily damage a cache module or a DIMM. Wear a snug-fitting, grounded electrostatic discharge (ESD) wrist strap. Note: If a DIMM fails, note which DIMM needs replacement based on the diagram displayed on the console. ACS displays the following CLI messages if a DIMM failure is detected: 1.

Use the steps in “Removing DIMMs” and “Installing DIMMs” to replace DIMMS in a cache module: 7. Insert the cache module into the appropriate bay and engage the retaining levers. Caution: Static electricity can easily damage a cache module or a DIMM.

Installing DIMMs Caution: Failure to allow the ports to quiesce can result in data loss. Quiescing can take several minutes. Use the following steps to install DIMMs in a cache module in dual-redundant configurations: The ECB must be disabled before disconnecting the ECB cable from the cache module. Failure to disable the ECB might result in cache module damage. Note: Before installing DIMMs, note the following: ■ New cache modules arrive without DIMMs installed; the DIMMs are packaged separately.

13. Follow on-screen instructions to install the cache module and to restart the “other controller.” Note: A controller restart can take as long as 60 seconds, indicated by the temporary cycling of the port LEDs and a flashing Reset button. Note: If the “other controller” did not restart: a. Press and hold the “other controller” Reset button. b. Reseat the “other controller” program card. c. Release the Reset button.
