Use the following procedure to configure L-Server usage changes:
Repeat 1. to 4. the same number of times as the number of physical servers which are used for usage change.
Release a physical server
When creating an L-Server specifying "Physical Server" from the [Server] tab, if it matches the following conditions, it is necessary to release the physical server from the L-Server. If the server does not match the following conditions, it is not necessary to release the physical server.
When specifying "Physical Server"
Another L-Server is already assigned to the physical server that has been specified.
When specifying "Pool"
An L-Server is assigned to all physical servers in the specified server pool
Execute the rcxadm lserver detach command, and release the physical servers from the L-Server.
# rcxadm lserver detach -name L-Server_name -type server <RETURN> |
For L-Server_name, specify an L-Server that has already been assigned to a physical server.
After releasing the physical servers from the L-Server, do not start the released L-Server until 2. to 4. are complete. If the released L-Server is started, it is necessary to perform releasing of the physical server in 1.
Create an L-Server
Create an L-Server, using the procedure in "5.1 Creation Using an L-Server Template".
When creating an L-Server for the second or later time, do so with "None" set for the image. Deploy cloning images after that.
For details, refer to the information about deploying cloning images in the "ServerView Resource Coordinator VE Setup Guide".
Change L-Server configuration
Execute the rcxadm lserver modify command, and in the XML file of the L-Server change the content of the AutoPreserve element to "true".
Performing this operation, releases the server resources automatically when they are powered-off, and saves storage and network resources in preparation for the next startup.
With this configuration, method 2 can be used for switching from the server allocated in step 1. to another server.
When operating using method 2, in the XML file of L-Server, specify "Automatic" or the "server_pool_for_use" in the "Primary" element.
For details on the command, refer to "E.3.1 rcxadm lserver".
For details on the XML file, refer to "H.3 L-Servers".
An example of an XML file is described below.
Example
<?xml version="1.0" encoding="utf-8"?>
<Resources>
<LServer name="lserver-test4" label="x">
<Policy>
<Repurpose>true</Repurpose>
</Policy>
<Primary>
<PhysicalServer name="BX900-slot1" /> or <Pool name="/TenantA/ServerPool" />
</Primary>
</LServer>
</Resources> |
Stop the L-Server
If an L-Server is operating, stop it.
For details, refer to "Stopping an L-Server" in "5.2 Power Operations".
