Page 15 Overview This chapter describes the overview of LPAR migration. Overview HVM Navigator User's Guide - Migration...
Page 16 LPAR migration is the function to transfer an LPAR from a server blade to another one. You can execute LPAR migration to maintain server blades and use resources such as CPU, memory, NIC, and FC HBA efficiently. By executing LPAR migration, MAC address and WWN assigned to the LPAR to migrate are transferred along with other kinds of configuration data.

Page 30: Time Period For Migration
Time period for migration There is a difference with the time period to have an LPAR migrate between Shutdown mode and Concurrent Maintenance mode. Time period for Shutdown mode It takes about 5 minutes that an LPAR migrates in Shutdown mode though the time period varies depending on the type of guest OS running on the LPAR and the application software operating on the guest OS.

It’s necessary that a shared NIC port with the theoretical bandwidth of over 1Gbps (actual bandwidth of over 900Mbps) to execute LPAR migration in Concurrent Maintenance mode.
Page 88 Concurrent Maintenance The recommended network configurations which fulfill the above requirements are shown in the following figures. Configure migration paths according to the following network configurations.

Page 237: Backing Up And Restoring Hvm Configuration
Backing up and restoring HVM configuration When there are LPARs which have failed to be recovered, backed up HVM configuration is necessary. So, back up HVM configurations on the source and destination server blades before and after executing LPAR migration. In addition, do not back up an HVM configuration through an SC/BSM, the web console for CB500, or the web console for CB2500 while saving the HVM configuration or executing LPAR migration because a defective HVM...

Page 239: Changing Hvm System Time On Destination Hvm
Changing HVM system time on destination HVM When you change HVM system time on the destination HVM while executing LPAR migration, the clock on the guest OS running on the LPAR to migrate is not transferred accurately because the changed HVM system time influences the clock on the guest OS.
Page 240: Setting Network Segment Assigned To Activated Lpars As Migration Path
Setting network segment assigned to activated LPARs as migration path When you set any of the network segments such as 1a, 1b, and so on assigned to one or more activated LPARs as migration paths for the source and destination HVMs and execute LPAR migration in Concurrent Maintenance mode, the network load caused by LPAR migration in Concurrent Maintenance mode affects the network performance on the activated LPARs.

Changing VNIC System No. on the system environment where LPAR migration has been executed MAC addresses assigned to shared NIC ports and virtual NIC ports on LPARs on an HVM may be duplicated, when you set a VNIC System No., which has been set for another HVM, for the HVM on the system where LPAR migration has been executed.
Page 243: Service Ratio After Migration
Service ratio after migration Migration functions of HVM Navigator carry the existing service ratio value, which is used for allocation of shared CPU resources to an LPAR, from the source LPAR to the destination LPAR as it is. Attention has to be paid, however, that the service ratio value after the migration means the ratio relative to the service ratios already allocated to the other LPARs on the same destination HVM.

When such an LPAR migrates, check the network settings.

Certain FC HBA port is changed from shared to dedicated When an LPAR on the source or destination server blade which the shared FC HBA port whose vfcID is "1" is assigned migrates, the following problems occur. Duplication of displayed or retrieved WWN When the FC HBA port set to shared mode is changed to dedicated mode, WWN of the FC HBA port are displayed or retrieved wrongfully in the following windows and by the following command.

Page 252: Clock On Guest Os On The Lpar To Migrate In Concurrent Maintenance Mode
LPAR to migrate, you can adjust the clock of the guest OS to HVM system time by executing “Adjust LPAR Time” in Date and Time screen in HVM screen, instead. For “Adjust LPAR Time”, see Hitachi Compute Blade 2000 USER’S GUIDE, Hitachi Compute Blade 500 Series Logical partitioning manager User’s Guide, or Hitachi Compute Blade 2500 Series Logical partitioning manager User Guide.
Page 253: Checking If The States Of Fc Hba Ports Are Stable
Checking if the states of FC HBA ports are stable When you execute LPAR migration in Concurrent Maintenance mode or roll back WWNs, check if all of the states of FC HBA ports installed both on the source and destination server blades are stable. If any of the states are unstable, wait a while without executing LPAR migration in Concurrent Maintenance mode or rolling back WWNs.

Page 256: Policy Migration
Policy migration You cannot register entries for both Shutdown mode and Concurrent Maintenance mode together in a migration policy. Executing migrations by operating multiple HVM Navigators Do not migrate LPARs from or to an HVM by operating the HVM in multiple HVM Navigators simultaneously.
Page 257: Sc/Bsm Alerts For Shutdown Mode
SC/BSM alerts for Shutdown mode You can confirm the events of Migration functions of HVM Navigator in SC/BSM alert messages. An alert message classified “Information” is taken at every start and end of Migration functions of HVM Navigator at the source and at the destination.
Page 258: Sc/Bsm Display After Migration With Windows Server 2008 R2
SC/BSM Display after Migration with Windows Server 2008 When a server running Windows Server 2008 R2 and using NIC teaming migrates by means of Migration functions of HVM Navigator, SC/BSM display of partitions and LPAR numbers after such migration may sometimes remain unchanged.
Page 259: Migrating Lpar Form The Standby Server Blade After Cold Standby Switching
Migrating LPAR form the standby server blade after Cold standby switching When you have an LPAR migrate from the standby server blade to another server blade after "Cold standby switching" and then you execute "Recover to active system", 2 LPARs with the same configuration are created on 2 server blades: the standby server blade and another server blade.
Page 260: Test Of Configuring N+M Cold Standby
Test of Configuring N+M Cold Standby Do not execute the alert for test of configuring N+M cold standby during migration and execute LPAR migration during test of configuration N+M cold standby because the LPAR to migrate might disappear or MAC addresses and WWNs might be duplicated.
Page 261 In order to avoid inadvertent shutdown of HVM during migration of LPARs, HVM Navigator suppresses the auto shutdown until the migration executed by Migration functions is complete. By doing so, the HVM remains active even during any scheduled migration where all LPARs on the HVM become deactivated (power-off state) to save power or to execute scheduled maintenance.
