When attempting to do Live Partition Mobility (LPM) in your environment, use the Live Partition Mobility Preparation Checklist. The assumption for using this checklist is that you previously set up your LPM environment based on the Live Partition Mobility Setup Checklist or the IBM PowerVM Virtualization Introduction and Configuration, SG24-7940, an IBM® Redbooks® publication. As part of the LPM operation, a validation is done but there are certain things the validation cannot check. This checklist describes the tasks that cannot be checked automatically. The checklist provides some basic details. To see more detailed information about each, see the IBM PowerVM Virtualization Managing and Monitoring, SG24-7590, which is also a Redbooks publication.
For related information about this topic, refer to the following IBM Redbooks publication:

Live Partition Mobility Preparation Checklist
|HMC tasks:||Complete = X||Comments|
|1. Check HMC hardware level:|
|2. Check the HMC software level for compatibility with the entire configuration using the IBM® Fix Level Recommendation Tool (FLRT) at this address:|
|Systems tasks:||Complete = X||Comments|
|1. Check source and destination system firmware levels and have all the recommended fixes for Partition Mobility (use FLRT).|
|2. Check source and destination system firmware levels for compatibility using the firmware support matrix Web site: http://www-01.ibm.com/support/knowledgecenter/8286-42A/p8hc3/p8hc3_firmwaresupportmatrix.htm|
|Virtual I/O Server (VIOS) tasks:||Complete = X||Comments|
|1. Check source and destination VIOS levels (use FLRT)|
|2. For the one or more VIOS servers that are serving network access to the mobile partition using a Host Ethernet Adapter (HEA) connected to a Shared Ethernet Adapter (SEA), ensure the “promiscuous” mode attribute is set on the HEA group.|
|3. For the one or more VIOS servers that are serving storage to the mobile partition on both the source and destination system, ensure both VIOS servers see the same disks (use the odmGet or lspv command) required by the mobile partition and have the no_reserve attribute set on those disks.|
|4. Verify that the physical Fibre Channel adapters that are assigned to the source and destination VIOS logical partitions support NPIV. Run the lsnports command to view the physical ports on the physical Fibre Channel adapters that support NPIV.||Not applicable (N/A) for vSCSI.|
|5. Verify that the switches to which the physical Fibre Channel adapters on both the source and destination VIOS logical partitions are cabled support NPIV. Run the lsnports command to view the fabric support of the physical ports on the physical Fibre Channel adapters. If the fabric support is 1, the physical port is cabled to a switch that supports NPIV.||N/A for vSCSI.|
|Mobile Partition tasks:||Complete = X||Comments|
|1. Check the software levels (use FLRT).|
|2. For each virtual Fibre Channel adapter on the mobile partition, verify that both worldwide port names (WWPNs) are assigned to the same set of logical unit numbers (LUNs) on the SAN.|
1. In the navigation pane, open Systems Management and select Servers.
2. Click the server on which the mobile partition is located.
3. In the navigation pane, select the mobile partition.
4. From the Tasks menu, click Properties. The Partition Properties window opens.
5. Click the Virtual Adapters tab.
6. Select a virtual Fibre Channel adapter slot.
7. From the Actions menu, click Properties. The Virtual Fibre Channel Adapter Properties window opens, showing the WWPN pair. Record both addresses.
9. Click Close to return to the Partition Properties window
|N/A for vSCSI.|
|3. Verify that the mobile partition has access to the virtual Fibre Channel adapters on the source VIOS logical partition.
||N/A for vSCSI.|
|4. An IBM i logical partition cannot be moved while an NPIV (virtual Fibre Channel) attached tape device is varied on.||N/A for IBM AIX and Linux partitions.|
|5. The IBM i partition must not be assigned a virtual SCSI optical or tape device at the time of the operation.||N/A for AIX and Linux partitions.|
