A Using XP12000 disk arrays with EVA GL disk arrays
attached as subordinated external storage disk
arrays

Preface

This appendix describes the procedure and relevant recommendations for configuring HP StorageWorks
XP12000 and EVA GL (EVA3000 or 5000) disk arrays where the EVA is used as a highly available
external storage disk array.
For the XP12000 to properly manage highly available (HA) connectivity to an EVA GL disk array, the
XP12000 and EVA must have firmware versions 50-04-28-00/00 or later and v3.028 or later,
respectively. The firmware specified for the EVA contains EVA Active/Passive controller capability only. EVA
Active/Active controller capability is not yet supported for external storage use. For more information
about the XP12000 and EVA GL series of disk arrays, visit the HP storage web site:

Configuration

Physical disk array connections

The XP12000 can use multiple fibre channel connections to an attached EVA. The two XP12000-EVA
configuration examples in the following sections—minimum and expanded—are designed with fibre
channel switches to maximize the ability of separate hosts to directly use the EVA in addition to the
XP12000. This also allows for connecting hosts to the EVA that run software applications such as
HP StorageWorks Command View EVA and System Insight Manager so the EVA can be managed in-band
as well as monitoring its operational status. The XP12000 does not forward detailed SIM (status) messages
the EVA generates during operation. Monitoring all EVAs must be done by a host connected in-band to the
EVA via a fibre channel.
