WebScale™
If a new host joins the cluster and its priority conflicts with some other host in the
cluster, the host will not be accepted as part of the cluster. The rest of the cluster will
continue to handle the traffic as before. A message describing the problem will be
written to the Windows NT the Event log. Please see the Execution and Control
section for more information on error logging and cluster operations.
Initial State
This parameter specifies whether this host should immediately join the cluster when
Windows NT is started. Leave this box unchecked if you want this host to start without
joining the cluster. Hosts can be commanded to join and leave cluster dynamically by
using WebScale command-line control tool. Please see the Execution and Control
section for more information on cluster operations.
Dedicated IP Address
This parameter specifies this host's unique IP address used for network traffic not
associated with the cluster (for example, telnet access to a specific host within the
cluster). It should be entered in standard Internet dotted notation (ex. 1.2.3.4); be sure
to enter the periods between the numbers within the address. This IP address is used to
individually address each host in the cluster and hence should be unique for each host.
In general, it is the original IP address assigned to the host prior to selecting an IP
address for cluster operations.
WebScale needs to know the dedicated IP address when a single network interface card
(NIC) is used to handle both cluster network traffic and network traffic to the dedicated
IP address. (In this case, both the cluster's IP address and the dedicated IP address are
bound to the single NIC.) WebScale will ensure that all traffic to the dedicated IP
address is unaffected by WebScale's current configuration, including:
when this host is running as part of the cluster,
when WebScale is disabled due to parameter errors in the registry, or
when the WebScale license key is valid and current.
If you use separate NICs to handle cluster network traffic and network traffic to the
dedicated IP address, only the cluster's NIC will be bound to the WebScale driver and
network traffic to the dedicated IP address will not be seen by the WebScale driver.
