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.
Capacity and free
Space
The target must have enough space to store the data from the source. This
amount of disk space will depend on the applications and data files you are
protecting. The more data you are protecting, the more disk space you will
need. You must also have enough space on the target to process and apply
the system state data.
Full-Server Failover performs several validation checks to determine if
adequate disk space is available. First, the target must have enough free
space on its system volume to hold the entire volume(s) (free and used) from
the source. If this first validation check passes, then no additional checks are
necessary. Otherwise, there must be at least enough free space on the target
system volume to store the system path (including the location of the
Windows files, Program Files, and Documents and Settings) from the source.
If this second validation check passes, then no additional checks are
necessary. If this second validation fails, Full-Server Failover will check to see
if a previous failover may have been attempted. Since Full-Server Failover can
reuse the disk space from a previous failover attempt, it will add the size of
that data to the amount of free space available. If that is enough space for the
failover, the failover will continue. If not, you will either have to select a
different target or delete files on the target to free disk space.
