About this document

This document contains instructions for replacing an HSG60

and HSG80 cache module in an HP StorageWorks HSG60 and

HSG80 subsystem. Replacement procedures for the following

include:

■ Replacing a cache module in HSG60 and HSG80

single-controller configurations, page 2

■ Replacing an HSG60 and HSG80 cache module in

dual-redundant controller configurations, page 4

Prerequisites and special considerations

■ Single-to-Dual-redundant Configuration Upgrade—For

instructions on upgrading a single-controller configuration

to a dual-redundant controller configuration, refer to

HP StorageWorks HSG60 and HSG80 Array Controller

and Array Controller Software Maintenance and Service

Guide. A copy of this guide can be downloaded from the

HP website at:

■ Cache Module Memory Configuration—The

replacement cache module normally uses DIMMs from the

cache module being replaced. When replacing DIMMs,

you must install DIMMs in the replacement cache module

in same position as they were in the cache module that is

being replaced.

General information

Replacing a cache module involves transferring the cache

memory DIMMs from the failed cache module to the

replacement cache module. Use the procedures in this section

to replace a cache module in either single or dual-redundant

controller configurations.

Note: In dual-redundant configurations, both cache modules

must

contain the same memory configuration, regardless of the ACS

version.

Figure 1 and Figure 2 (on page 2) provide general information

about the cache module.

Note: See Figure 1 and Figure 2 (on page 2) for specific

component references while replacing cache modules.

Removing a cache module 5 Perform the following steps to remove a cache module in a single-controller configuration: 1 1. Determine whether the controller is operational, and then complete one of the following two options: 4 3 If the controller is not operational, proceed to step 7. 4. Run the Fault Management Utility (FMU) to obtain the last failure codes, if necessary. 5. Shut down “this controller” by entering the following command: Figure 1: Cache module SHUTDOWN THIS_CONTROLLER 2 3 4 5 ■ 3.

d. e. Installing a cache module Remove the cache module from the enclosure. Place the cache module on a grounded antistatic mat or in an antistatic bag. Perform the following steps to install an HSG60 and HSG80 cache module in an HSG60 and HSG80 subsystem. These instructions are for cache modules in a single-controller configuration. Note: The DIMMs must be removed for installation in the replacement cache module. Tip: When replacing DIMMs, see Figure 3. 8.

1. For the controller associated with the cache module to be replaced, complete the following substeps: Note: If the controller did not restart, use the following steps: 1. Press and hold the Reset button. 2. Reseat the controller program card. 3. Release the Reset button. a. Connect a PC or terminal to the maintenance port. b. Run the Virtual Terminal Display (VTDPY) utility by entering the following command: 6.
PAGE 5
Caution: Early removal of the cache module can result in a controller crash. To prevent this, wait for FRUTIL to instruct you to remove the cache module. FRUTIL will display the following message when it is ready for you to remove the cache module: b. Disable the ECB by pressing the battery disable switch until the status light stops flashing. This should take approximately 5 seconds. c. Disconnect the ECB Y-cable from the “other controller” cache module. d.
PAGE 6
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.) 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.

H H 4. For the operational controller, note that in Mirrored mode, FRUTIL initializes the mirrored portion of the replacement cache module, checks for old data on the cache module, and then restarts all device ports. After device ports restart, FRUTIL tests the cache module and the ECB. After the tests conclude, the device ports are quiesced, and a mirror copy of the cache module data is created on the newly installed cache module.
PAGE 8
Note: After you enter the appropriate SET command, the controller restarts. A controller restart can take as long as 60 seconds, indicated by the temporary cycling of the port LEDs and a flashing Reset button. The SET command copies the subsystem configuration from “this controller” to the “other controller.” c. Verify the failover configuration by entering the following commands: SHOW THIS_CONTROLLER SHOW OTHER_CONTROLLER d.
