130Veritas Cluster Server: Configuring Oracle VM Server for SPARC for high availabilityOracle VM Server for SPARC guest domain migration in VCS environmentthe domain migration defaults to warm migration. For more details on supportedconfigurations, read Chapter 9, Migrating Domains in the Oracle® VM Server forSPARC 2.1 Administration Guide.VCS supports the following three varieties of Oracle VM Server for SPARC domainmigration:■Guest migration from one VCS node to other VCS node in the cluster, forexample:sys1# ldm migrate logical domain1 sys2■Guest migration from a VCS node to a non-VCS node, for example:sys1# ldm migrate logical domain1 sys3■Renaming the logical domain during the migration to the target system, forexample:sys1# ldm migrate logical domain1 sys2:logical domain2Prerequisites before you perform domain migrationPerform the following prerequisites before you perform a domain migration:■■■■■Verify that the value of IntentionalOffline attribute for LDom type is 1. Notethat 1 is the default value.Make sure that the LDom resource for the LDom that you plan to migrate isin an ONLINE or OFFLINE steady state.To rename the logical domain when you migrate it, make sure that theLDomName attribute for the LDom resource in VCS is localized with the targetLDom name for the target node. When you rename it, VCS can continue tomonitor the LDom after migration.Make sure that CfgFile attribute for LDom is configured before migration.Make sure that RemoveLDomConfigForMigration attribute is set beforemigration. If this attribute is set, the LDom Agent removes the LDomconfiguration from the system on which an offline or clean is called. Thisarrangement helps in the scenario when a LDom is failed-over to a target nodeand is migrated back to the source node. In the presence of LDom configurationon the source node, migration would not be possible. Refer to the LDom Agentattribute description in the Bundled Agents Reference Guide for Solaris formore information.
