Node Operations
These are the operations that you can perform on a node.
ADD
The ADD command configures the named HPC compute node for use by the DSC, and adds the compute node to the set of nodes that are managed by the DSC.
Note |
|---|
| Installing the DSC does not add compute nodes to the DSC by default. |
Syntax
DSC NODE ADD name /datapath:dscdatasharepath /temppath:dsctempsharepath [/service:headnode] [/f]
Remarks
The /datapath parameter sets the local path for the directory that is used by the HpcData share. For example, specifying /datapath:C:\L2H\data results in a share named \\MyServer\HpcData, whose data is stored in the C:\L2H\data directory on MyServer. If the local directory doesn’t exist, it will be created.
The /temppath parameter sets the local path that is used by the HpcTemp share. For example, specifying /temppath:C:\L2H\temp results in a share named \\MyServer\HpcTemp whose data is stored in the C:\L2H\temp directory on MyServer. If the local directory doesn’t exist, it will be created.
If the HpcData or HpcTemp share already exists and points to a directory on a node, you can use the /f option ("force") to delete the existing shares and create new ones in the directory that you specify. If you do not use the /f option, then the shares that point to the original directories will continue to be used, and a warning message will be printed.
The /service option specifies the name of the cluster’s head node. Use the /service option if the environment variable %CCP_SCHEDULER% is not set. This environment variable identifies the location of the head node and is read by the Dsc.exe program. Although the environment variable is set by default on the head node itself, it is not set by default on the client.
Examples
DSC NODE ADD MyCluster-Node-01 /TempPath:c:\L2H\Temp /DataPath:c:\L2H\Data DSC NODE ADD MyCluster-Node-02 /TempPath:c:\L2H\Temp /DataPath:c:\L2H\Data
This sequence of commands configures the named HPC compute nodes, and adds them to the DSC that runs on the cluster's head node.
REMOVE
The REMOVE command removes a DSC node from the set of nodes that are managed by the DSC.
Syntax
DSC NODE REMOVE name [/service: headnode]
Remarks
The /service option specifies the name of the cluster’s head node. Use the /service option if the environment variable %CCP_SCHEDULER% is not set. This environment variable identifies the location of the head node and is read by the Dsc.exe program. Although the environment variable is set by default on the head node itself, it is not set by default on the client.
See Removing a Node from the DSC for more information.
Examples
DSC NODE REMOVE MyCluster-Node-01
This command removes the named DSC node from the set of DSC nodes.
LIST
The LIST command lists the compute nodes that have been added to the DSC.
Syntax
DSC NODE LIST [/service: headnode
Remarks
The /service option specifies the name of the cluster’s head node. Use the /service option if the environment variable %CCP_SCHEDULER% is not set. This environment variable identifies the location of the head node and is read by the Dsc.exe program. Although the environment variable is set by default on the head node itself, it is not set by default on the client.
Examples
DSC NODE LIST
This command lists the compute nodes that are in the DSC, which is located on the head node.
VIEW
The VIEW command displays detailed information about the compute node that is specified by name.
DSC NODE VIEW MyUser-cn1 /service:MyUser-hn
Here is an example of the output:
Node MyUser-cn1:
State = ReadWrite
HpcTemp Local Path = \\MyUser-CN1\HpcData
HpcData Local Path = c:\L2H\data
Free Space = 479819542528
Syntax
DSC NODE VIEW name [/service: headnode]
Remarks
The /service option specifies the name of the cluster’s head node. Use the /service option if the environment variable %CCP_SCHEDULER% is not set. This environment variable identifies the location of the head node and is read by the Dsc.exe program. Although the environment variable is set by default on the head node itself, it is not set by default on the client.
Examples
DSC NODE VIEW MyCluster-Node-01
This command displays information about the named node.
