1 Overview of HP StorageWorks XP
Virtualization Adapter
HP StorageWorks XP Virtualization Adapter (XP Virtualization Adapter) is a Perl interface between
VMware Site Recovery Manager (SRM) and HP StorageWorks Disk Arrays. The interface enables
SRM to provide automatic access to remote data copies when virtual machines become unavailable
locally.
HP StorageWorks XP Virtualization Adapter performs the following functions for SRM:
Discovers disk arrays
Discovers replicated LUNs
Fails over storage for testing (test a recovery plan)
Fails over storage for recovery (execute a recovery plan)

Discovery of disk arrays and LUNs

During SRM configuration, XP Virtualization Adapter is called to discover available arrays and
replicated LUNs.
The following information is discovered:
Storage Array Ids serial number
Model: for example, 60-03-20/FF
Product: XP_RAID
Storage Port Id: Port WWN
Replicated LUNs and Ids: LDEV number and LUN WWN
Remote Storage Array Ids: serial number
Remote LUN Ids: LDEV number
NOTE:
Remote SVOL is available to the groups through XP RAID Manager horcm.conf, and are replicated
between protected and recovery XP disk arrays using XP Continuous Access Synchronous, XP
Continuous Access Asynchronous, and XP Continuous Access Journal software.

Failover testing

XP Virtualization Adapter provides information and performs XP operations for nondisruptive testing
of SRM failover recovery plans. SRM uses the information gathered during the discovery process to
create point-in-time copy of remote LUNs. After testing verifies that the point-in-time copies of the LUNs
can be recovered after failure of the local array (via a recovery plan), SRM uses XP Virtualization
