HP StorageWorks Storage Mirroring Full-Server Failover Evaluation Guide (T2558-96331, April 2009)

4 - 2
Network adapters You must map at least one NIC from the source to one NIC on the target. If
the source has more NICs than the target, some of the source NICs will not
be mapped to the target. Therefore, the IP addresses associated with those
NICs will not be available after failover, unless you configure the advanced
options. If there are more NICs on the target than the source, the additional
NICs will still be available after failover.
File system format The source and the target must have the same file system format. For
example, an NTFS volume cannot be sent to a FAT volume.
HAL type and
version
The Windows hardware abstraction layer (HAL) refers to a layer of software
that deals directly with your computer hardware. The HAL type and version do
not have to be identical, but they must be compatible between the source and
the target. If the two are incompatible, Full-Server Failover will warn you. In
that case, you must upgrade or downgrade the target.
Administrative
shares
The Full-Server Failover Manager must be able to access administrative
shares on the source and the target.
Boot volume
configuration
The target boot volume cannot be a dynamic disk configuration. The boot
volume is the disk volume that contains the Windows operating system and
supporting files. By default, the operating system files are in the \Windows
folder, and the supporting files are in the \Windows\System32 folder. The
boot volume might be the same volume as the system volume, but that
configuration is not required.
System volume The target must have the same system volume as the source. The system
volume is the disk volume that contains the hardware-specific files that are
needed to start Windows. The system volume might be the same volume as
the boot volume, but that configuration is not required.
Logical volumes There are no limits to the number of logical volumes, although you are bound
by operating system limits. The source and the target must have the same
number of logical volumes, and the source and the target must have the same
drive letters. For example, if the source has drives C: and D:, the target
cannot have drives D: and E:. In this case, the target target must also have
drives C: and D:.
System path The source and the target must have the same system path. The system path
includes the location of the Windows files, Program Files, and Documents and
Settings.
Storage Mirroring
path
Full-Server Failover must be installed on the system path on the source and
the target.
Storage Mirroring
data state
The source should be from a time when the Storage Mirroring data state is
good. If you are using snapshots, you may want to use a snapshot from the
last good data state.
