the Primary IP address, which specifies the cluster-wide IP address to be used for
all hosts,
the Subnet mask for the cluster's primary IP address,
the Full Internet name, which specifies the full Internet name for the WebScale
cluster (for example, cluster.your-company.com),
the Network address, which specifies the cluster-wide Network address for the
network cards in all hosts,
the Multicast support button to enable or disable the use of a multicast cluster
MAC address,
the Remote password to restrict access to the cluster for remote control
operations,
the Confirm password field that confirms the remote access password, and
the Remote control button to enable or disable remote control operations.
The values entered in the dialog box within this section must be the same for all the
host computers in the cluster.
For more information on each of these parameters, please refer to the corresponding
subsections.
Please note that changing some parameters requires the cluster to be rebooted. These
parameters can only be entered while running WebScale Setup from the Network setup
dialog, and they cannot be modified when WebScale Setup is launched from the
command line with webscale setup.
Cluster's Primary IP Address
This parameter specifies the cluster's primary IP address in standard Internet dotted
notation (for example, 1.2.3.4); be sure to enter the periods between the numbers within
the address. This address must be set identically for all hosts in the cluster. This IP
address is used to address the cluster as a whole, and it should be the IP address for the
Full Internet name that you specify for your cluster. If you alias several IP addresses to
the cluster (e.g., in a multi-homed web server), then only the primary (main) IP address
needs to be entered here. For more on Internet names, please see the Full Internet name
section.
Subnet Mask
This parameter specifies subnet mask for the IP address entered immediately above it.
The mask is also entered in standard Internet dotted notation (for example,
255.255.255.192); be sure to enter the periods between the numbers within the address.
