Migrating Bound or Inactive Domains
Only a few domain migration restrictions apply to a bound or inactive domain because such domains are not executing at the time of the migration. Therefore, you can migrate between different platform types, such as SPARC T3 to SPARC T5 platforms, Fujitsu SPARC M12 platforms or Fujitsu M10 platforms, because no runtime state is being copied across.
The migration of a bound domain requires that the target machine is able to satisfy the CPU, memory, and I/O constraints of the domain to be migrated. If these constraints cannot be met, the migration will fail.
 | Caution - When you migrate a bound domain, the virtual disk back-end options and mpgroup values are not checked because no runtime state information is exchanged with the target machine. This check does occur when you migrate an active domain. |
The migration of an inactive domain does not have such requirements. However, the target machine must satisfy the migrated domain's constraints when a bind is later attempted or the domain binding will fail.
Note - After a domain migration completes, save a new SP configuration to the SP of both the source and target systems. As a result, the state of the migrated domain is correct if either the source or target system undergoes a power cycle.
Starting with Oracle VM Server for SPARC 3.5, an SP configuration can be saved automatically following a successful migration. For more information, see Saving Post-Migration SP Configurations Automatically.
Migration Requirements for Virtual I/O Devices
For an inactive domain, no checks are performed of the virtual I/O (VIO) constraints. Therefore, the VIO servers do not need to exist for the migration to succeed. As with any inactive domain, the VIO servers must exist and be available at the time the domain is bound.
Migration Requirements for PCIe Endpoint Devices
You cannot perform a domain migration on an I/O domain that is configured with PCIe endpoint devices. This requirement applies to bound domains but not to inactive domains.
For information about the direct I/O (DIO) feature, see Creating an I/O Domain by Assigning PCIe Endpoint Devices.
Migration Requirements for PCIe SR-IOV Virtual Functions
Except for SR-IOV Ethernet virtual functions, you cannot perform a domain migration on an I/O domain that is configured with PCIe SR-IOV virtual functions. This requirement applies to bound domains but not to inactive domains.
For information about the SR-IOV feature, see Creating an I/O Domain by Using PCIe SR-IOV Virtual Functions.
For information about migrating a domain that has SR-IOV Ethernet virtual functions, see Migrating a Domain That Has an SR-IOV Ethernet Virtual Function Assigned.
