This section explains how to modify L-Server specifications. Use the following procedure to modify L-Server specifications:
[Solaris Containers]
L-Server specifications cannot be modified from the ROR console. Modify them from the global zone.
The Procedure when Using the GUI
Right-click the target L-Server in the orchestration tree, and select [Change Settings]-[Modify Specification] from the popup menu.
The [Modify an L-Server] dialog is displayed.
Change the values.
Click <OK>.
The current values for each item are displayed in the [Modify an L-Server] dialog. Items that have been changed are indicated with an asterisk ("*") in front of the item.
The Procedure From the Command Line
From the command-line, execute rcxadm lserver modify or rcxadm lserver set.
For details on the rcxadm lserver modify command and the rcxadm lserver set command, refer to "3.6 rcxadm lserver" in the "Reference Guide (Command/XML) CE".
Changeable Items
The items for which specifications can be changed differ depending on whether the L-Server is physical or virtual.
Changing Physical L-Server Specifications
The following items can be changed when the power status of the physical L-Server is OFF.
FC path
Boot Mode
CPU Performance (*1)
Number of CPUs (*1)
Memory Size (*1)
*1: Can be specified when using blade servers. When you start the L-Server after setting "Resource release" (for allocating and releasing resources to and from L-Servers) and adjusting CPU and memory settings, a physical server will be selected according to the modified conditions.
Changing Virtual L-Server Specifications
The following items can be changed when the power status of the virtual L-Server is ON. For details, refer to the manuals of VM products.
CPU Performance
Number of CPUs
Memory Size
OS Type (When no images are not deployed)
[Oracle VM]
The OS type cannot be changed, regardless of whether images are deployed or not.
[KVM]
When changing the specifications for the OS types (when images have not been deployed) of virtual L-Servers, for KVM it is necessary to perform settings based on the OS type that the user intends to install.
When the OS type differs from the OS installed on the virtual L-Server, operation is not guaranteed.
The following shows the VM products where changes may be made while the power is on:
VMware
Hyper-V
KVM
The items that can be changed depend on the type of VM product and the settings. Refer to "Table 17.2 Items that can be changed while the power is on" for details.
Resource Name | Modification | VMware | Hyper-V | KVM |
|---|---|---|---|---|
Number of CPUs | Add | Yes (*1) | No | No |
Detaching a Disk | No | No | No | |
CPU Performance | Add | Yes | Yes | Yes |
Detaching a Disk | Yes | Yes | Yes | |
Memory Size | Add | Yes (*1) | No | Yes |
Detaching a Disk | No | No | Yes | |
Operating System Type | Modification | No | Yes | Yes |
*1: Can be changed if memory/CPU hot plug is enabled. The memory/CPU hot plug is enabled on the virtual L-Server created by Resource Orchestrator.
[VMware] [Hyper-V]
When CPU reserve, memory reserve, and initial memory capacity have been set for the L-Server, changing the CPU performance and memory size to values smaller than those values is not possible. To change these settings, use the command-line or VM management software. (*1)
[VMware]
When the memory size is changed, the limit value of memory is also changed.
However, when the limit value of memory has been set to "Unlimited", only the memory size is changed.
When changing the memory limit setting, use the VM management software to do so. (*1)
For details on the configuration method, refer to the manual of the VM management software.
When VMware FT has been configured on a virtual machine linked with a virtual L-Server, server redundancy settings cannot be modified.
Check whether the memory/CPU hot plug has been enabled from the VM management software if an existing VM guest is to be linked to a virtual L-Server.
If it is not enabled, enable the setting from the VM management software. Refer to the manual for the VM management software network device for information on how to enable the memory/CPU hot plug with the VM management software.
[Hyper-V]
When dynamic memory settings are changed from disabled to enabled, without specifying memory capacity or initial memory capacity for the L-Server, the values for the following items of the virtual machine will be same as the memory size.
Initial Memory Capacity (StartupRAM)
Maximum Memory
When using dynamic memory or memory weight, it is necessary to apply Service Pack 1(SP1) or later to the VM host, and upgrade SCVMM when using System Center Virtual Machine Manager 2008 R2 Service Pack 1(SP1) or later. When dynamic memory is enabled and memory weight is specified, modification of the L-Server fails unless there are a VM host and SCVMM with SP1 applied.
*1: The modified value is reflected on the configuration of the L-Server by periodic queries made to the VM management software. For details on reflection of L-Server configuration by periodic queries, refer to "17.2 Modifying an L-Server".
Note
Immediately after a snapshot is restored, there may be differences between the configuration of VM guests managed by L-Server and those managed by VM management software.
The differences in VM guest configuration are reflected on the configuration of the L-Server by periodic queries made to the VM management software.
For details on reflection of L-Server configuration by periodic queries, refer to "17.2 Modifying an L-Server".
When changing the values for server redundancy for an L-Server to which a virtual machine is already allocated, the virtual machine is not changed, only L-Server attributes are changed.
When making changes while the power of the virtual L-Server is on, only the configuration of the virtual L-Server can be changed.
Follow the procedures for the OS's running on the virtual L-Server to have the changes recognized by the OS's.
