Upgrading From an HSZ70 to an HSG80 Array Controller

This guide provides a procedure for upgrading an HSZ70 Array Controller to an HSG80 ACS Version 8.3 Array

Controller. It contains a roadmap, twelve sections with step-by-step instructions, and an appendix with tables for

creating an HSZ70 to HSG80 unit map. Refer to the HSG80 Array Controller ACS Version 8.3 Configuration and

CLI Reference Guide for information on configuring the HSG80 Array Controller.

Impact of Architectural Differences between the HSZ70 and HSG80

The HSZ70 to an HSG80 Array Controller upgrade described in this document is a well-defined

process. There will be an impact on your operations and applications due to the architectural

differences between the HSZ70 and HSG80 Array Controllers. In this section, you will find the

key areas that you will need to be aware of to make the entire process successful.

The most significant difference lies in the architecture of the interconnect between the Array

Controller and the Host Bus Adapter. The HSZ70 provides a connection to an UltraSCSI Wide

host bus, on which it presents up to 8 individual target IDs (TID) with up to 8 Logical Unit

Numbers (LUNs) per target. The HSG80 establishes its connection via a Fibre Channel

Arbitrated Loop (FC-AL) to a Fibre Channel Host Bus Adapter installed in a server. The server

hen maps the Arbitrated Loop Physical Addresses (AL_PAs) to SCSI target IDs to be used by the

server’s operating system.

The difference in these methodologies is most readily apparent in the assignment of Unit

Numbers on the HSZ70 and HSG80. Unit Numbers on the HSZ70 follow the DTZL format,

where the ‘T’ is the SCSI target ID, the ‘Z’ is always zero and the ‘L’ is the Logical Unit

Number. Together, the ‘T’ and ‘L’ components of the Unit Number provide the SCSI target ID

and LUN, which will be visible to the server’s operating system.

The Unit Numbers on the HSG80 range from D0-D99 for Fibre Port 1 and D100-D199 for Fibre

Port 2. When combined with the Arbitrated Loop Physical Addresses (AL_PAs) assigned to

Fibre Port 1 and Fibre Port 2, the Unit Numbers will be mapped to SCSI target IDs and LUNs,

by the server. For example, if Fibre Port 1 is assigned an AL_PA of hexadecimal 72, then Unit

D0 will be mapped to SCSI target ID 64 and LUN 0; Unit D1 will be SCSI target ID 64 and

LUN 1, etc.

Based on this difference in mapping Fibre Channel Unit Numbers to the server SCSI target IDs

and LUNs, there will be new device assignments after the upgrade. Please make sure to

accurately record these changes. Then use this record to update partition information for

filesystem mounts and any applications, such as databases or logical volume managers that make

use of these new device names.

COMPAQ StorageWorks Upgrading From an HSZ70 to an HSG80 Array Controller If after reading this guide, you determine that you want assistance with upgrading your RAID system, please contact a Compaq Services representative. NOTE The HSZ70 Array Controller uses a trilink connector with SCSI host bus cables. The HSG80 Array Controller uses fibre optic host cables. The following procedures assume that the user has the appropriate fibre channel cables and hubs to connect to the host subsystem.

Service Guide 5.0 Preparing the Client NOTE If you are using a Tru64 system, skip this section (5.0) and proceed to Section 6.0. If the StorageWorks Command Console (SWCC) was used to manage this HSZ70 subsystem, perform the following steps to save a copy of the HSZ70 configuration. If SWCC was not used, skip this section and go to Section 6.0 Removing the Server Components. The HSZ70 subsystem configuration can be saved using SWCC.

PAGE 9
Service Guide 7.0 Preparing the HSZ70 Use the following steps to prepare the HSZ70 for upgrade: 1. Connect a PC or terminal to the operational controller’s maintenance port. The controller that you are connected to is “this controller.” 2. If the HSZ70 storagesets were originally created with the SAVE_CONFIGURATION option enabled then the current configuration of the HSZ70 will be retained on the disk in that storageset.

COMPAQ StorageWorks 9.0 Upgrading From an HSZ70 to an HSG80 Array Controller Installing the HSG80 Components Use the following steps to install the HSG80 components: CAUTION ESD can easily damage a cache module or controller. Wear a snug-fitting, grounded ESD wrist strap. Make sure you align the cache module and controller in the appropriate guide rails. If you do not align the modules correctly, damage to the backplane can occur.

Service Guide If a previous configuration was saved and the message above was not displayed, the configuration was not restored. To retry the restore: Restart the procedure at Step 1 of this section. If the configuration is still not restored, then either the HSG80 controller(s) was not set to factory default or, the configuration was not previously saved. Refer to Appendix B to restore the HSG80 controller(s) to a factory default state.

Service Guide 10.0 Installing the Second HSG80 Controller Use the following steps to install the second HSG80 controller: 1. Once the controller has restarted install the “other controller” and its cache module by starting FRUTIL with the following command: HSG80> RUN FRUTIL FRUTIL displays the following: Do you intend to replace this controller’s cache battery? Y/N 2. Enter N(o). FRUTIL displays the FRUTIL Main menu: FRUTIL Main Menu: 1. Replace or remove a controller or cache module 2.
PAGE 16
COMPAQ StorageWorks Upgrading From an HSZ70 to an HSG80 Array Controller Perform the following steps: 1. Turn off the battery for the new cache module by pressing the battery’s shut off button for five seconds 2. Connect the battery to the new cache module. 3. Insert the new cache module in slot B within 4 minutes. NOTE A countdown timer allows a total of four minutes to install both the cache module and controller. If you exceed four minutes, “this controller” will exit FRUTIL and resume operations.
PAGE 17
Service Guide NOTE In mirrored mode, FRUTIL will initialize the mirrored portion of the new cache module, check for old data on the cache module, and then restart all device ports. After the device ports have been restarted, FRUTIL will test the cache module and the ECB. After the test completes, the device ports will quiesce and a mirror copy of the cache module data will be created on the newly installed cache module. NOTE One or two host fibre cables may be attached, depending on the configuration. 10.
