HP Integrity Virtual Server Manager 6.2 User Guide

Migration status and error notification
The migration status of a VM — including the direction of migration, percentage completion per
phase (for online migration only), and error messages — is displayed on the VM Properties General
tab. The VSP Virtual Servers tab also indicates migration status (use this tab to monitor the migration
of multiple VMs). For more information, see “VM or vPar properties general tab” (page 61) and
“VSP Virtual Servers tab” (page 31).
If errors occur during an attempt to migrate a VM online, the VSP Virtual Servers tab (for the source
VSP) displays the Migration Error icon ( ) next to the name of the affected VM. Information about
the migration-related errors is on the VM Properties General tab. For more information about status
icons, see “Status indicators” (page 137).
Various conditions can cause an online migration to abort: insufficient resources on the target host,
busy source or target hosts, a slow private network connection, an excessively busy guest (VM
operating system and applications), and so on. When a migration aborts, the guest continues to
run, unaffected, on the source VSP. Therefore, these are not serious errors. You can attempt the
online migration again when the blocking conditions improve.
After a VM successfully migrates to another VSP, it is placed in the Not Runnable state on the
source VSP. A VM in this state cannot be modified or started. If you never intend to migrate the
VM back to the source VSP, you can remove the VM configuration by using the Integrity Virtual
Server Manager Delete→Virtual Machine... menu item.
The state of the VM is displayed by the HW column on the VSP Virtual Servers tab. The Not
Runnable state is indicated by the following status icon: . The VM Properties General tab also
displays the state of the VM (in the Virtual Hardware Status field).
Adjusting online migration phase timeout values
To protect the guest's workload, the online migration software limits the amount of time spent in
each phase of the migration. If necessary, the VSP administrator can carefully adjust migration
time outs for each phase by using the hpvmmodify -x command, as documented in the HP-UX
vPars and Integrity VM Administrator Guide manual.
Starting the Migrate Virtual Machine wizard
To migrate one or more VMs, follow these steps:
1. If you want to migrate a single VM, access any VM Properties view, and skip to the next step.
If you want to migrate several VMs, access the VSP Virtual Servers tab or any tab that allows
you to select multiple VMs. Then select the VMs to migrate by clicking the appropriate check
boxes.
2. To start the Migrate Virtual Machine wizard, select Tools→Migrate Virtual Machine... from
the Integrity Virtual Server Manager menu bar. This displays the first of two Migrate Virtual
Machine wizard screens, the Step 1 screen as shown in Figure 62.
NOTE: The Tools→Migrate Virtual Machine... option is enabled from any VM Properties
view or from any tab on which one or more VMs are selected.
