134Veritas Cluster Server: Configuring Oracle VM Server for SPARC for high availabilityOracle VM Server for SPARC guest domain migration in VCS environmentMigrating Oracle VM guest when VCS cluster is installed in the guestdomains to manage applications for Oracle VM Server for SPARCversion 2.1 and abovePerform one of the following procedures when you want a migration of guestdomain when VCS cluster is configured between guest domains.To perform a migration of the LDom when VCS is installed in the guest domain thatmanages the applications in the guest domains for Oracle VM Server for SPARCversion 2.1 and above◆Use the ldm command for migration.ldm migrate [-f] [-n] [-p password_file] source_ldom \[user@target_host[:target_ldom]For example:Sys1# ldm migrate ldom1 Sys2Migrating Oracle VM guest when VCS cluster is installed in the guestdomains to manage applications for Oracle VM Server for SPARCversion 2.0The domain migration is a warm migration.Note: You do not have to start and stop LLT and GAB. In a warm migration, LLTand GAB restart themselves gracefully.To perform a domain migration for an LDom when VCS is installed in guest domains1 Stop VCS engine. Use the hastop -local -force command on the systemthat has the logical domain that you plan to migrate. Perform this step sothat GAB does not have to kill the VCS engine process when the migration iscomplete. GAB wants all clients to reconfigure and restart when theconfiguration is not in sync with other members in the cluster.2 If CVM is configured inside the logical domain, perform this step. Set thevalue of the LLT peerinact parameter to 0 on all nodes in the cluster. You setthe value to zero so that while the logical domain is in migration, the systemis not thrown out of the cluster by the other members in the cluster. If theCVM stack is unconfigured, the applications can stop.See the Veritas Cluster Server Administrator’s Guide for LLT tunable parameterconfiguration instructions.

Unconfigure and unload the vxfen module in the logicaldomain. Perform this step so that GAB does not panic the node when thelogical domain migration is complete.4 Migrate the logical domain from the control domain using the ldm interface.Wait for migration to complete.ldm migrate [-f] [-n] [-p password_file] source_ldom \[user@target_host[:target_ldom]For example:Sys1# ldm migrate ldom1 Sys25 Perform this step if you performed step 3. Load and configure vxfen modulein the logical domain. See the Veritas Cluster Server Administrator’s Guidefor information about I/O fencing and its administration.6 Perform this step if you performed step 2. Reset the value of the LLT peerinactparameter to its original value on all nodes in the cluster.See the Veritas Cluster Server Administrator’s Guide for LLT tunable parameterconfiguration instructions.7 Use the hastart command to start VCS engine inside the logical domain.Figure 6-12 illustrates a logical domain migration when VCS is clustered betweencontrol domains and single-node VCS in the guest domain monitors applications.
