COMPAQ StorageWorks Upgrading From an HSZ70 to an HSG80 Array Controller

Page 2 EK-HSG80-UP. B01

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.

CAUTION

The HSG80 controller(s) that will be used in this procedure

must be factory default. If the controller(s) have been used or

the packages have already been opened, they must be

restored to the factory default state before starting the

upgrade process. The procedure described in Appendix B can

be used to restore the factory default configuration; however,

that procedure could also erase customer and configuration

data; therefore, it should NOT be used on a RAID subsystem

containing data.

1.0 Upgrade Restrictions

Before starting the upgrade procedure review this entire document and the following criterion to

determine if this upgrade will meet your requirements.

• Upgrades Supported:

⇒ HSZ70 Version 7.1 to HSG80 Version 8.3 on:

⇒ Windows NT

⇒ HP-UX

⇒ SGI IRIX

⇒ SUN Solaris

⇒ Digital Unix/Tru64 Unix

⇒ IBM AIX

⇒ StorageWorks Command Console Version 2.0 to Version 2.1.

• Table 1-1 compares the maximum number of HSZ70 SCSI Logical Units versus the maximum

number of HSG80 Fibre Channel units supported by the various operating systems. If your

server operating system supports fewer Fibre Channel Logical Units than SCSI Logical Units,

the system administrator will need to consolidate some Logical Units.
