Method Details [hide private]

CheckArguments(self)

source code 

Check arguments.

Overrides: LogicalUnit.CheckArguments

ExpandNames(self)

source code 

ExpandNames for CreateInstance.

Figure out the right locks for instance creation.

Overrides: LogicalUnit.ExpandNames

BuildHooksEnv(self)

source code 

Build hooks env.

This runs on master, primary and secondary nodes of the instance.

Overrides: LogicalUnit.BuildHooksEnv

_ReadExportInfo(self)

source code 

Reads the export information from disk.

It will override the opcode source node and path with the actual information, if these two were not specified before.

Returns:
the export information

_ReadExportParams(self, einfo)

source code 

Use export parameters as defaults.

In case the opcode doesn't specify (as in override) some instance parameters, then try to use them from the export information, if that declares them.

CheckPrereq(self)

source code 

Check prerequisites.

Overrides: LogicalUnit.CheckPrereq

Exec(self, feedback_fn)

source code 

Create and add the instance to the cluster.

Overrides: LogicalUnit.Exec
