SUNW.LogicalHostname, LogicalHostname - resource type for IP addresses
SUNW.LogicalHostname describes a resource type that manages the availability of a network address. A logical hostname is an IP address that can be migrated from one cluster node to another. Under cluster control, the address is configured down on one node and then brought up on another node.
See the clreslogicalhostname(1CL ) man page for information about administering this resource type.
The following extension properties are associated with the SUNW.LogicalHostname resource type:
Specifies whether the MONITOR_CHECK callback for a logical hostname should verify that a name resolver is available. This check is enabled by default. Disable this check if there is a possibility that the name service will not be available when the logical hostname is failing over, for example, if the cluster is running the HA for DNS data service and cluster nodes themselves are using it to resolve names.
Optional
True
Anytime
Specifies a list of hostnames managed by this resource. All hostnames must be on the same subnet. If you need more than one subnet for the resource group, create as many resources as there are subnets.
Optional
Empty list
When disabled
Specifies the list of IP addresses of the hostnames managed by this resource. Users are not allowed to provide the IP list. The IP list is obtained from the name service. Possible values are "+" (meaning to suppress the caching mechanism) and empty which is equivalent to not specified (meaning to enable the caching of IP addresses).
Optional
+
When disabled
Specifies a list of IPMP groups, trunk and DLMP link aggregations, and VNICs that are directly backed by link aggregations for each node. The format is pnm-object@node in a comma-separated list. A node is specified by its node ID number.
Required when used with the clresource command.
Optional when used with the clreslogicalhostname command, but not valid in the same clreslogicalhostname command that the –N option is used. If neither the NetIfList property nor the –N option is specified, the system attempts to generate the network interface list. See the description of the –N option in the clreslogicalhostname(1CL ) man page for further explanation of this behavior.
Empty list
Anytime
Specifies the netmask of all hostnames managed by this resource. All hostnames must be on the same subnet if this property is given with a specific netmask address. Other possible values are "+" (meaning to suppress the caching mechanism) and empty which is equivalent to not specified (meaning to enable the caching netmask).
Optional
+
When disabled
