Table C-1: Cluster Interconnect /etc/sysconfigtab Attributes Set by clu_create and clu_add_member

Subsystem	Attribute	Comment
`clubase`	`cluster_interconnect`	Interconnect type to be used for cluster internode communications. If a LAN interconnect is used, the `clu_create` and `clu_add_member` commands set this attribute to `tcp`. If Memory Channel is used, the scripts set it to `mct`.
`ics_ll_tcp`	`ics_tcp_inetaddr0`	The `clu_create` and `clu_add_member` commands set this attribute to the IP address of the physical cluster interconnect device (for example, `10.1.0.1`).
	`ics_tcp_netmask0`	Subnet mask used for the cluster interconnect. The `clu_create` and `clu_add_member` commands write the value 255.255.255.0 to this attribute.
	`ics_tcp_adapter0`	The `clu_create` and `clu_add_member` commands set this attribute to the name of the physical cluster interconnect device (for example, `tu0` or `nr0`).
	`ics_tcp_nr0`	If the `ics_tcp_adapter0` attribute indicates a NetRAIN set, this attribute is an array indicating the device names of the network adapters that make up the set.
