FenceVdsBaseCommand

public FenceVdsBaseCommand(T parameters)

Method Detail

getRerties

protected abstract int getRerties()

Gets the number of times to retry a get status PM operation after stop/start PM operation.

Returns:

getDelayInSeconds

protected abstract int getDelayInSeconds()

Gets the number of seconds to delay between each retry.

Returns:

getFencingSucceeded

protected boolean getFencingSucceeded()

setFencingSucceeded

protected void setFencingSucceeded(boolean value)

canDoAction

protected boolean canDoAction()

Overrides:

canDoAction in class CommandBase<T extends FenceVdsActionParameters>

executeCommand

protected void executeCommand()

Specified by:

executeCommand in class CommandBase<T extends FenceVdsActionParameters>

createExecutorForProxyCheck

protected FencingExecutor createExecutorForProxyCheck()

Create the executor used in the can do action check. The executor created does not do retries to find a proxy host, so that clients calling the can do action will get a quick response, and don't risk timing out.

Returns:

An executor used to check the availability of a proxy host.

DestroyVmOnDestination

protected void DestroyVmOnDestination(VM vm)

RestartVdsVms

protected void RestartVdsVms()

setStatus

protected void setStatus()

HandleError

protected void HandleError()

waitForStatus

protected boolean waitForStatus(String vdsName,
                    FenceActionType actionType)

setStatus

protected void setStatus(VDSStatus status)

handleSpecificCommandActions

protected abstract void handleSpecificCommandActions()
