You can perform several actions on logical servers from the
Virtualization Manager. For a description of the Virtualization Manager
menu options that perform these tasks, see “Virtualization Manager Menus”. A logical server can be active or inactive. An active logical server has
been bound to both an HP SIM node and a VSE workload, and is bound
to specific storage. Active logical servers can be in one of two states: powered on or powered
off. An inactive logical server has
been defined but is not currently bound to a specific physical server
or system. Inactive logical servers that have never been activated
might or might not be bound to storage. To view the attributes of a logical server, including its state,
hover over the node information icon ![[i]](./img/infoc.gif) in the Logical Servers perspective. The following
sections describe actions you perform that change or do not change
the state of logical servers. Actions that Change the Logical Server State | |
The following actions that you perform on a logical server change
the state of the logical server: Activate This operation binds a logical server to a physical server
or system. For this release, the two types of systems on which logical
servers can be activated are Virtual Connect enabled server blades
and ESX virtual machines. For Virtual Connect server blades, activating a logical
server creates a server profile and powers on the blade, by default.
If the blade has been provisioned with an operating system, activating
the logical server will boot it. For ESX virtual machines, activating a logical server
creates a new virtual machine on a preexisting hypervisor and powers
on the virtual machine, by default. If the virtual machine has been
provisioned with an operating system, activating the logical server
will boot it.
When you select a target on which to activate the logical server,
you are shown a Suitability rating that displays between one and five
stars, with the higher number of stars denoting that more excess resources
are available on the target server. An active logical server can be powered on or powered off. You
can optionally power on the physical server on which you are activating
the logical server. This is useful if you want to launch a software
tool for operating system provisioning. If, for example, you use media
to install the operating system, you can choose not to power on the
physical server when you first activate the logical server.
Deactivate This operation removes the association between a logical server and
a system. The storage binding remains, maintaining the hostname,
IP address, and user information on the operating system boot image. For Virtual Connect blades, the blade is shut down
and the server profile is disassociated from the blade. (The server
profile is maintained, however, and can be reactivated elsewhere.) For virtual machines, the virtual machine is shut
down, and the virtual machine definition is removed.
Actions that Do Not Change the Logical Server State | |
Some operations that you perform on a logical server do not
change the state of the logical server. The following list describes
these operations: Create The Create Logical Server wizard allows you to define
a logical server, which includes the identity of the logical server,
the amount of memory and CPU, and predefined network and storage configuration. You can specify a storage pool entry as the Virtual Connect
blade storage for the logical server, if you have defined storage
pool entries using the Manage Storage Pools screen. When you create a logical server, do not configure it to include
Virtual Connect blade storage that uses a local
disk. In addition, a local disk should not be put into
use at any time on a Virtual Connect blade that is running a logical
server. Copy This operation copies a previously created logical server
using a menu selection. This results in a new logical server with
a different name. Because you cannot modify the name of a logical server after
it is created, you should use Copy Logical Server to create a logical
server with the same definition and a different name. Delete This operation allows you to choose a recoverable or unrecoverable
deletion. A recoverable deletion (on an active or inactive logical
server) removes the logical server definition from the management
database. An unrecoverable deletion (on an inactive logical server)
removes the logical server definition from the management database,
removes the physical server profile or virtual machine from the compute
environment, and removes connectivity to storage and network devices. Import This operation imports the definition for an existing
physical server and creates an active logical server with that definition. Modify This operation allows you to modify or view the details
of an existing logical server. You can modify only an inactive logical
server. When you modify an inactive logical server, your changes are
saved for future use, and applied when you activate it. Move This operation moves an active logical server onto another
host. The host can be a blade (for a Virtual Connect blade logical
server), or a hypervisor (for an ESX virtual machine logical server). When you select a target on which to move a logical server,
you are shown a Headroom rating that
displays between one and five stars, with the higher number of stars
denoting that more excess resources are available on the target server. You can move an active logical server onto another host using
a menu selection, and by dragging and dropping the logical server
onto another blade or hypervisor in the Physical and Virtual perspective in VSE Visualization tab. Synchronize with Server Resources This operation
synchronizes the logical server database with the VM Manager and Virtual
Connect Enterprise Manager inventories. You might want to synchronize
if you create or remove inventory, by performing actions such as importing
a logical server, creating or deleting a VM Host, or creating or deleting
an enclosure in a Virtual Connect domain group. Synchronization is useful if, for example, you use VM Manager
to create a new VM Host, then activate a logical server. In that case,
the new VM Host might not be listed as an available target on the
Assign Logical Servers to Target Hosts screen. If you select Tools Logical ServersSynchronize..., then ToolsLogical ServersActivate..., the new VM Host
will be an available target on which you can activate the logical
server.
