About these instructions

This document contains instructions for replacing an

HP StorageWorks HSG60 or HSG80 array controller. Array

controller replacement procedures in these instructions

include:

■ Replacing HSG60 and HSG80 controllers in

single-controller configurations, page 3

■ Replacing HSG60 and HSG80 controllers in

dual-redundant controller configurations, page 5

Prerequisites and special considerations

Observe the following prerequisites and special considerations

before replacing an HSG60 or HSG80 array controller:

■ Single-to-Dual-redundant configuration upgrades—For

instructions on upgrading a single-controller configuration

to a dual-redundant controller configuration, refer to the

appropriate documentation that shipped with your array

controller or subsystem component.

■ DRM Configurations—If you are using HP StorageWorks

Data Replication Manager (DRM) with HSG60 or HSG80

controllers that need to be replaced, refer to the HP

StorageWorks HSG60 and HSG80 Array Controller and

Array Controller Software Maintenance and Service Guide

for specific instructions. A copy of this guide can be

downloaded from the HP website at:

http://h18006.www1.hp.com/products/storageworks/

acs/index.html

■ Hardware Compatibility—The replacement controller

hardware must be compatible with the remaining controller

hardware. Refer to product-specific release notes and

documentation for information regarding hardware

compatibility.

■ Software Compatibility—The software versions and

patch levels of the replacement controller must be the same

as that of existing subsystem controllers.

General information

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

information about the HSG60 and HSG80 array controllers and

specific host cable connections for each array controller type.

Tip: See the applicable array controller figure (Figure 1, Figure 2,

or Figure 3 on page 2) for clarification during the selected

procedures.

Note: The maintenance port cable shipped with the array controller

has a 9-pin connector for a PC connection only. If you are using a

terminal instead of a PC, obtain the optional maintenance port

cable.

Replacing HSG60 and HSG80 controllers in single-controller configurations Note: After the controller shuts down, the Reset button and the first three LEDs turn on (see Figure 5). This can take several minutes to occur, depending on the amount of data that needs to be flushed from the cache module. Proceed only after the Reset button stops flashing and remains on.

8. Disconnect all host bus cables or terminators from the controller. Use thin needle nose pliers to disconnect the cables if the extender clips are not installed on the optical cables. 1. Insert the replacement controller into controller A bay and then engage the retaining levers. 2. Connect a PC or terminal to the controller maintenance port. 3. Press and hold the Reset button while inserting the program card into the controller. 4.

Removing a controller 13. Determine whether the configuration restore process completed successfully, and then perform one of the following options: ■ Perform the following substeps if the configuration restore process did not complete successfully. a. b. c. ■ Perform the following steps to remove a controller in a dual-redundant controller configuration: Reset the PC or terminal baud rate to match the original configuration of the controller. Repeat step 10 and step 11 (on page 4).

Note: In Transparent Failover mode, units that failed over due to a RESTART command will revert back to preferred controller after about 1 minute. e. Exit VTDPY by pressing Ctrl+Y. f. Disable Failover mode, and take the controllers out of the dual-redundant configuration by entering the following command: c. Enter option 1 to remove the controller or cache module. The Replace or remove Options screen is displayed (see Figure 11). Replace or remove Options: 1.

5. For the controller to be replaced, complete the following substeps: b. Ensure that the controller configuration is customized to your needs, and then record the controller configurations (for example, Failover mode, cache module status, serial numbers, SCSI mode, mirrored and nonmirrored information, and so forth). c.

H For the replacement controller, complete the following substeps: H a. Remove the program card in the replacement controller, if it is installed. ■ H If the controller reported that the cache and mirrored cache (if enabled) is good in substep 3b, proceed to substep 3d. b. Insert the replacement controller (without the program card installed) into the appropriate bay, and then engage the controller retaining levers. ■ H c.
PAGE 9
Caution: Failure to clear an invalid cache message (especially a Cache is FAILED message) in substep 4c before setting the Failover mode can result in a recursive bugcheck condition that renders the controller unusable. H d. Disconnect the PC or terminal from the maintenance port of the replacement controller. 5. For the operational controller, complete the following substeps: a. Connect a PC or terminal to the maintenance port of the operational controller.
