When performing the following operations, choose a physical server that satisfies the conditions:
Create physical L-Servers
Start a physical L-Server
Switch over spare servers of physical L-Servers
Explains the prerequisites when using physical servers, and method for selecting a physical server while searching physical servers that satisfy the conditions.
Prerequisites when Using Physical Servers
The physical server that satisfies all of the following conditions will be the target of selection.
When "status" of physical server is "normal", "warning", or "stop"
Server switchover is not configured in the server resource tree
The information of the admin LAN specified in the physical L-Server and the information of the admin LAN for a physical server are the same
The server types (blade server or rack mount server) of the physical L-Server and the physical server are the same
The physical server is not used for another physical L-Server (*1)
All information for a physical server such as "CPU core count", "CPU clock speed", and "memory capacity" can be collected
Selection Method for Physical Servers
Select a physical server from a group of physical servers satisfying prerequisites using the following order of priority:
Describe the items in order of their priority.
Create physical L-Servers
The server in the server pool to which a high priority has been given (*2)
The server with the physical server configuration that is most similar to the L-Server definition
A server which is not allocated to another physical L-Server that was not running when starting up the previous time
A physical server that is in the same chassis as the server started at the last startup (when using a blade server)
A physical server which was started at the last startup
Start a physical L-Server
The server in the server pool to which a high priority has been given (*2)
The server with the physical server configuration that is most similar to the L-Server definition
A server which is not allocated to another physical L-Server that was not running when starting up the previous time
A physical server that is in the same chassis as the server started at the last startup (when using a blade server)
A physical server which was started at the last startup
When there was no physical server, and "HA" is specified for "Server Recovery", physical servers in the spare server pool are searched.
Switch over spare servers of physical L-Servers
The server in the server pool to which a high priority has been given (*2)
The server with the physical server configuration that is most similar to the L-Server definition
A server which is not allocated to another physical L-Server that was not running when starting up the previous time
A physical server that is in the same chassis as the server started at the last startup (when using a blade server)
A server that allows "Turn off forcibly" as spare server behavior (*3)
*1: Compare the physical L-Server definition and the physical server using the following conditions. A physical server with the same conditions or meeting all conditions is selected.
If model names are specified when specifying a physical L-Server
The "model names" are the same, or compatible
Number of NICs
If CPUs and memories are specified when specifying a physical L-Server
CPU core count
CPU clock speed
Memory size
Number of NICs
*2: When [Resource type] and [Spare server pool] are [Automatic], priority is given to a resource pool. If the priority of resource pools is the same, the resource pool is selected randomly.
*3: A physical L-Server for which "Turn off forcibly to use as a spare server" is set can use a server that allows "Turn off forcibly" as spare server behavior.
When the [Use a low spec server] checkbox for [Spare server specs] is checked, the servers will be selected as follows:
If model names are specified when specifying a physical L-Server
A physical server with the same server model as that in the L-Server definition is selected.
If CPUs and memories are specified when specifying a physical L-Server
Configurations are not checked.
When there are multiple physical servers with the same conditions, the server is selected using the internal logic of Resource Orchestrator.
