Domain Live Migration

6

This Chapter discusses live migration of domains to other, identical computers. You 
must use identical computers to perform live migrations, that is, the computer make 
and model number must be identical.

To perform live migration of domains, you must create a shared virtual disk before 
you perform the migration. This Chapter contains:

If you want to perform live migration of domains to other, identical, computers, you 
must create a shared virtual disk to be used during the live migration. You can set up a 
shared virtual disk in the following configurations:

■

OCFS2 (Oracle Cluster File System) using the iSCSI (Internet SCSI) network 
protocol

■

OCFS2 using SAN (Storage Area Network)

■

NFS (Network File System)

This section discusses creating a shared virtual disk in these configurations.

To create a shared virtual disk using OCFS2 on iSCSI:

Install the iscsi-initiator-utils RPM. The iscsi-initiator-utils RPM is available on the 
Oracle VM Server CDROM or ISO file.

rpm -Uvh iscsi-initiator-utils-6.2.0.742-0.5.el5.i386.rpm

Start the iSCSI service:

service iscsi start

Run discovery on the iSCSI target. In this example, the target is 10.1.1.1:

iscsiadm -m discovery -t sendtargets -p 10.1.1.1

This command returns output similar to:

10.1.1.1:3260,5 iqn.1992-04.com.emc:cx.apm00070202838.a2

10.1.1.1:3260,6 iqn.1992-04.com.emc:cx.apm00070202838.a3

10.2.1.250:3260,4 iqn.1992-04.com.emc:cx.apm00070202838.b1
