Note: Refer to the for HP StorageWorks Command View EVA online Help for
information about these procedures. All of these procedures need to be completed for
your host to use the virtual disks.
1. Initialize the storage system and create disk groups. When you first view
the EVA5000/EVA3000 from the Command View EVA software, the storage
pool is presented as uninitialized storage. Follow documented procedures for
initializing your storage systems and creating disk groups in the
HP
StorageWorks Command View EVA Enterprise Virtual Array Getting Started Guide.
2. Add the host to the storage system. Before the host can use the storage
system’s virtual disks, the host must be known to the storage system. Adding
the host creates a path from the storage system to one host adapter.
3. Add ports to all host adapters. From the Host Properties page, choose
Add Port to add connections to the remaining HBA host adapters.
4. Create and present virtual disks to the host. Follow documented
procedures for creating your virtual disk family and presenting the disks to the
host in the
HP StorageWorks Command View EVA Enterprise Virtual Array Getting
Started Guide.
Several options are available for selecting a path preference and mode for a virtual
disk. To optimize Load Balancing the load should be evenly distributed between
controller A and controller B. The boot default selected controller may be chosen
by setting the controller Preferred path/mode. It is recommended that either
Path A - Failover only or Path B - Failover only be used. This mode allows
Secure Path to control a restore to the original controller following a controller
failure and replacement.
Note: Path A - Failover/failback and Path B - Failover/failback are not supported on
Secure Path for Linux. That feature is designed for operating systems that cannot run
Secure Path.
