WINS
When Storage Mirroring Recover failover occurs, Windows initiates WINS registration
with the target’s primary WINS server to associate the source server’s name with the
target’s primary IP address. In an environment with just one WINS server, no additional
processing is required. In an environment with more than one WINS server, WINS
replication will distribute the updated WINS registration to other WINS servers on the
network. The length of time required for all WINS servers to obtain the new registration
depends on the number of WINS servers, the WINS replication architecture, and the
WINS replication interval. Clients will be unable to access the target until their WINS
server has received the updated WINS information. You can reduce the time required for
the WINS updates, thereby decreasing the wait time for the end users, by scripting the
WINS updates in the Storage Mirroring Recoverfailover scripts. You have two options for
scripting the WINS updates.
l
—This option registers a user-specified server with WINS. It
requires less network overhead but administrator group membership on all WINS
servers.
l
—This option forces WINS replication. It does not require any
special privileges, but requires system and network resources to complete WINS
replication. The impact on the network will depend on the size and complexity of
the WINS architecture.
