Preparing the source and destination Virtual I/O Server logical partitions for partition mobility
You must verify that the source and destination Virtual I/O Server (VIOS) logical partitions are configured correctly so that you can successfully migrate the mobile partition from the source server to the destination server by using the Hardware Management Console (HMC). This verification includes tasks such as verifying the version of the VIOS partitions and enabling the mover service partitions (MSPs).
To prepare the source and destination VIOS partitions for active or inactive partition mobility, complete the following tasks.
| VIOS planning tasks | Active mobility task | Inactive mobility task | Information resources |
|---|---|---|---|
| 1. Ensure that at
least one VIOS partition is
installed and activated on both the source and destination servers. If the mobile partition receives virtual storage resources from redundant VIOS partitions on the source server, install the same number of VIOS partitions on the destination server, if possible. Remember: In some situations, you can select
the option to override virtual storage errors if possible and migrate
a logical partition to a destination system with less redundancy.

Ensure that the source and destination VIOS partitions are at
the following versions:

| 3. Ensure that the MSP is enabled on one or more source and destination VIOS
partitions. Note: From VIOS Version
2.2.0.11, Fix Pack 24, Service Pack 1 to VIOS Version
2.2.1.0, you cannot use a VIOS logical partition that
uses a shared storage pool as a MSP.

| 4. If the mobile partition uses shared memory, verify that at least one VIOS
partition is assigned to the shared memory pool on the destination server (subsequently referred to
as a paging VIOS partition) and that it is at release version 2.1.1, or later. If the mobile partition accesses its paging space device redundantly through two paging VIOS partitions and you want to maintain this redundancy on the destination server, verify that two paging VIOS partitions are assigned to the shared memory pool on the destination server.

| 5. If the mobile partition uses shared memory, verify that the shared memory pool on the destination server contains a paging space device that satisfies the size requirements and redundancy configuration of the mobile partition. | X | X | Verifying that the destination shared memory pool contains an available paging space device |
| 7. Ensure that you do not start a partition mobility or a Suspend/Resume operation when the alt_disk_install command is running on the source VIOS. | X | X |
