26 HP StorageWorks XP Fast Recovery Solution for Windows Server 2003: Administration Guide
Important performance issues
These issues can affect FRS performance:
• Excessive traffic on the Ethernet LAN.
• Viruses that slow down network traffic.
• A firewall that slows traffic between the servers hosting FRS and the
CV server. Any firewall must be open between these systems. If you
experience copy timeouts, the firewall is the likely cause.
Important limitations
• FRS supports only basic disk configuration, not dynamic disks.
• FRS supports multiple arrays of the same model, but all arrays must be
managed using the same Command View XP workstation.
• Only one FRS command is supported at a given time on an FRS
recovery or production server, regardless of how the command is
initiated (GUI or CLI). To prevent execution of concurrent commands,
HP recommends that you run FRS from only one management console
or command line interface.
• FRS supports only a homogeneous disk array solution. If you want to
run FRS on an XP1024 and an EVA6000 disk array, for example, you
will need two mutually exclusive recovery servers—one per disk array
with no shared components.
• Only normal, LUSE, and OPEN-V volumes are supported with this
version of the product. Custom volumes (CVS volumes) are currently
not supported. For example, a volume that reports back with the
“-CVS” extension (such as OPEN-3-CVS) is not supported.
• Command devices must not be configured as production or recovery
LUNs.
