HP Insight Virtualization Manager with Logical Server Management 6.1 User Guide

Moving ESX, Hyper-V, and HP Integrity virtual machine logical servers
If you are moving a logical server from one virtual machine to another, the following restrictions
apply.
• You can move virtual machine logical servers within a set of hypervisors of the same type
(ESX, Hyper-V, Integrity VM). You cannot move virtual machine logical servers from one
type of hypervisor to another type.
• For non-live moves, HP recommends that you shut down the virtual machine on which the
logical server was activated before you move it. Otherwise, the virtual machine will be
ungracefully shut down and powered off.
A shutdown is not necessary if your virtual machine is configured for live migration, and
you are moving the logical server within the same ESX cluster using VMware VMotion.
• For non-live moves, moving a logical server shuts down the source virtual machine and
removes the virtual machine definition. The target virtual machine is powered on, by default.
If the source virtual machine is powered off, you can uncheck the Power On the VM or the
Blade checkbox to keep the target virtual machine powered off after the move.
• An HP Integrity virtual machine must be powered on before you can perform a live move.
• When you power on an ESX virtual machine that was moved to a new location, a VMware
message appears, asking you if you want to create a new UUID (Logical) for the virtual
machine, or keep the old one. Select Keep, then click OK to continue powering on the virtual
machine.
• You can move ESX virtual machine logical servers among multiple clusters, as long as the
clusters are contained in one VMware vCenter.
• There may be a delay in the population of possible target hosts if the CMS and vCenter are
in different network domains (subnets). Similarly, if you are moving the logical server using
drag and drop, there may be a delay before the hosts appear as valid targets.
Virtual machine target hosts
Target hosts on which a logical server can be moved are shown in the Target Hosts table. Select
one target host in the Target Hosts table by clicking the radio button to the left of the target
host. Hover your mouse over the error symbols for more information.
• Target hosts with the best fit are sorted to the top of the Target Hosts table.
• Target hosts with an acceptable fit are shown with error symbols in the table columns. You
can override the filter criteria and select a target host with error symbols in the Target Hosts
table.
A yellow triangle in the Headroom column denotes an error returning Capacity Advisor
data.
• You cannot select a target host from the Rejected Target Hosts table. The red circle symbol
in the Failed column contains the reason for rejection. Other errors are denoted by error
symbols.
