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.
