This section explains how to allocate resources to, and release resources from, L-Servers.
Even if there are no resources to allocate to L-Servers, flexible configuration and operation, such as creating only L-Server definitions in advance, is possible.
[Solaris Zones (Solaris 10)] [OVM for SPARC]
When a virtual machine created on a VM host not managed with server management software is linked to an L-Server, "Allocating and Releasing Resources to L-Servers" is set according to the value of the definition file. After linking a virtual machine to an L-Server, it cannot be modified.
For details on definition files, refer to "17.8.1 Installation".
Configure the following settings, when creating an L-Server.
Create an L-Server definition
If only creating an L-Server definition, configure "None (Definition only)", when creating an L-Server.
For details, refer to "16.2.1 [General] Tab" and "16.3.1 [General] Tab".
Only IP addresses/MAC addresses/WWNs are allocated to the created L-Server, and "[defined]" is displayed.
Automatically release server resources for L-Servers
If releasing server resources when the L-Server is turned off, set [Resource release] during L-Server creation.
For details, refer to "16.2.2 [Server] Tab" and "16.3.2 [Server] Tab".
When the power of an L-Server for which this setting is configured is turned off, "[preserved]" is displayed.
Note
When sharing resources on the same physical server between L-Servers using the usage change function, set [Resource release] on the L-Server where the server resource is allocated.
When the server resources are allocated to an L-Server for which [Resource release] is not configured, the server resources cannot be shared.
Note
For an L-Server from which VM guests have been deleted using server virtualization software, "unknown" is displayed for the resource allocation status.
For details, refer to "3.9 When the Status is "unknown", Operations of a Virtual L-Server Fail." in "Troubleshooting".
Figure 17.3 State Transition of L-Servers
L-Servers can be deleted when their status is something other than "undefined" (specifications have not been defined).
