Restrictions for Zone Network Addresses

The configuration of a zone's network addresses depends on the level of high availability (HA) you require. You can choose between no HA, HA through the use of only IPMP, or HA through the use of IPMP and SUNW.LogicalHostName.

Your choice of a zone`s network addresses configuration affects some configuration parameters for the zone boot resource. For more information, see Registering and Configuring Sun Cluster HA for Solaris Containers

• If HA for the zone's addresses is not required, then configure the zone`s addresses by using the zonecfg utility.

• If only HA through IPMP protection is required, then configure the zone`s addresses by using the zonecfg utility and place the zone's addresses on an adapter within an IPMP group.

• If HA through IPMP protection and protection against the failure of all physical interfaces by triggering a failover is required, choose one option from the following list:

  • If you require the SUNW.LogicalHostName resource type to manage one or a subset of the zone's addresses, configure a SUNW.LogicalHostName resource for those zone's addresses and not by using the zonecfg utility. Use the zonecfg utility only to configure the zones's addresses that are not required to be under the control of the SUNW.LogicalHostName resource.

  • If you require the SUNW.LogicalHostName resource type to manage all the zone's addresses, configure a SUNW.LogicalHostName resource with a list of the zone`s addresses and do not configure them by using the zonecfg utility.

  • Otherwise configure the zone's addresses by using the zonecfg utility and configure a separate redundant IP address for use by a SUNW.LogicalHostName resource, which must not be configured using the zonecfg utility.
