public abstract class CommonVmPoolWithVmsCommand<T extends AddVmPoolWithVmsParameters>
extends AddVmPoolCommand<T>

This class responsible to create vmpool with vms within. This class not transactive, that mean that function Execute not running in transaction. From other hand, each vm added to system and attached to vmpool in transaction(one transaction for two operation). To make it work, Transaction generated in Execute function. Transactions isolated, that mean if one of vms not added from some reason(image not exists, etc) - it not affect other vms generation Each vm created with this format: {vm_name}_{number} where number runs from 1 to vms count. If one of vms to be created already exists - number increased. For example if vm_8 exists - vm_9 will be created instead of it.

Constructor Detail

CommonVmPoolWithVmsCommand

protected CommonVmPoolWithVmsCommand(Guid commandId)

Constructor for command creation when compensation is applied on startup

Parameters:

commandId -

CommonVmPoolWithVmsCommand

public CommonVmPoolWithVmsCommand(T parameters)

Method Detail

getVmsCount

public int getVmsCount()

GetPoolId

protected abstract Guid GetPoolId()

executeCommand

protected void executeCommand()

This operation may take much time, so transactions timeout increased to 2 minutes

Overrides:

executeCommand in class AddVmPoolCommand<T extends AddVmPoolWithVmsParameters>

CanAddVmPoolWithVms

public static boolean CanAddVmPoolWithVms(Object vmTemplateId,
                          ArrayList<String> reasons,
                          int vmsCount,
                          Guid storagePoolId,
                          Guid storageDomainId,
                          int vmPriority)

canDoAction

protected boolean canDoAction()

Overrides:

canDoAction in class CommandBase<T extends AddVmPoolWithVmsParameters>

CheckFreeSpaceOnDestinationDomains

public boolean CheckFreeSpaceOnDestinationDomains()

getStorageDomainId

public NGuid getStorageDomainId()

Overrides:

getStorageDomainId in class AuditLogableBase

getAddVmsSucceded

protected boolean getAddVmsSucceded()

isVmPoolNameValidLength

protected boolean isVmPoolNameValidLength(String vmPoolName)

Check if the name of the VM-Pool has valid length, meaning it's not too long. Since VMs in a pool are named like: 'SomePool_22', the max length allowed for the name is the max VM-name length + room for the suffix: - (length() + 1) In deciding the max length for a VM name, take into consideration if it's a Windows or non-Windows VM

Parameters:

vmPoolName - name of pool

Returns:

true if name has valid length; false if the name is too long
