Preface
This appendix describes the procedure and relevant recommendations for configuring HP StorageWorks
XP12000/XP10000/SVS200 and EVA3000/5000 Disk Arrays where the EVA is used as a highly
available external storage array.
The XP firmware version and external firmware version must be compatible. Consult your HP account
support representative for the latest firmware version required.
Configuration
Physical array connections
The XP12000/XP10000/SVS200 can use multiple Fibre Channel connections to an attached EVA. The
two XP12000/XP10000/SVS200-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/XP10000/SVS200. 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/XP10000/SVS200 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.
Minimum physical configuration for HA
For highly available (HA) functionality to be possible, each EVA controller must be connected to the
XP12000/XP10000/SVS200 so there is at least one fiber channel path from each
XP12000/XP10000/SVS200 cluster to one of the separate EVA controllers through their respective Fibre
Channel switch connections. Figure 73 illustrates this connection.
Figure 73 XP12000/XP10000/SVS200-EVA minimum connections for HA
This configuration allows the XP12000/XP10000/SVS200 to execute basic failover and failback
operations with the EVA array subordinated. Unlike the MSA series of arrays, the EVA allows access to
