There are two methods for changing virtual machine policies. These are operated from the vSphere Web Client.
When the same policy is applied to multiple virtual machines, create a new policy and apply it to a virtual machine whose policy is to be changed. When applying another policy to a virtual machine, perform the procedure in "Applying Another Policy to Virtual Machine".
When a policy is changed, the policy settings of all the virtual machines to which the policy is applied can be changed all at one time. To edit a policy, perform the procedure in "Editing Policy".
The vSphere Web Client operating procedure is as follows:
Select the virtual machine.
Click Policies on the Manage tab.
Click Edit VM Storage Policies....
Select and apply the policy.
Perform the procedure in "3.3.3 Confirmation of Policy Application".
Click VM Storage Policies from Home.
Select the policy to edit.
Click Edit VM Storage Policies....
Edit the policy.
The method of editing is the same as that of "3.3.1 Creation of Policy".
Specify when to apply the edited policy.
When applying right away, policies on all virtual machines where the policy is applied are changed simultaneously.
When applying later, apply the procedure in "Applying Another Policy to Virtual Machine".
Perform the procedure in "3.3.3 Confirmation of Policy Application".
Policy change is performed in the background as with policy application.
Note
Do not change items described as "Not Possible" in "Modifiable" in the table of each function in "3.3.1 Creation of Policy". When changed, the Compliance Status becomes "Noncompliant".
When changing the policy, do not change the following properties. If they are changed, their Compliance Status becomes "Noncompliant". Also, the esccs11301 message is displayed on the Event screen of VMware vCenter Server and on the Event Log screen of Web Console. Take action according to the message.
Function | Property |
|---|---|
Automated Storage Tiering (Advanced) | Number of Layers, Execution Mode |
Security (Advanced) | Data encryption |
If the esccs11002 message is output when applying the policy, perform the procedure in "Editing Policy" to change the policy.
When specifying storage migration using Storage vMotion, if the "Virtual Machine Backup" property in the policy is also specified to be changed, it remains as before changed. Therefore, upon completion of Storage vMotion, reapply the policy with the following procedure:
Select the virtual machine that performed Storage vMotion.
Click Policies on the Manage tab.
Click Edit VM Storage Policies....
Click OK.
All property settings can be changed.
When changing to "Auto" or "Manual", the backup operation starts according to the set value.
Point
When performing an automatic backup with an external scheduler, select "Manual".
Note
Even if you select "Auto" or "Manual", if the following settings are done (settings that do not create backup), "Disable" is automatically set.
"0" is specified for Number of Snapshot Generations, and
"Disable" is specified for Clone Backup.
When changing to "Disable", a backup cannot be performed. If the following resources have been acquired before changing to "Disable", these resources continue to remain, and a restore is possible.
Snapshot backup (Snapshot backup history)
Clone backup (Clone backup history)
Point
Backup histories are not automatically deleted. To delete backup histories, ask the storage administrator.
The following changes are only effective when Operation Mode is set to "Auto" or "Manual".
This is only enabled when the Operation Mode is set to "Auto".
The changed settings are reflected immediately and automatic operation is started according to the settings after the change.
The settings after the change are reflected when the next Snapshot is executed. When saved generations are reduced, the Snapshot backups that are generation-overflows are deleted when the next backup is executed.
When this item is changed to "0" and Clone Backup is set to "Disable", Operation Mode is automatically set to "Disable". For this reason, the Snapshot backups already created are not deleted. When Snapshot backups are not required, ask the storage administrator to delete Snapshot backups.
The settings after the change are reflected when the next backup is executed.
When changing from "Disable" to "Enable", the Clone backup is taken when the next backup is executed.
When changing from "Enable" to "Disable", a Clone backup is not taken when the next backup is executed. However, as the created Clone backup is not deleted, restoring from the created Clone backup is possible. When Clone backup is not required, ask the storage administrator to delete Clone backup.
The settings after the change are reflected when the next Snapshot is executed. From the next backup on, the Snapshot backup is executed with the specified option.
Point
When changing the virtual machine backup function policy, update the policy for all virtual machines or objects ("VM home") representing the virtual machine from the update screen.
The property settings other than Number of Layers or Execution Mode can be changed.
The settings after change are reflected to the next relocation.
Only when the number 2 or 3 is specified for Number of Layers, the settings can be changed.
Only when the number 2 or 3 is specified for Number of Layers, the settings can be changed.
Only when the number 3 is specified for Number of Layers, the settings can be changed.
Only when the number 2 or 3 is specified for Number of Layers, the settings can be changed.
Point
When managing virtual machines with this product according to a policy designed by storage administrators, specify "Any" for Execution Mode and change the policy.
All the property settings can be changed.
When this property value is changed to "Enable", Automated QoS is started according to the set value.
When this property value is changed to "Disable", Automated QoS is stopped.
Only when Automated QoS Enable/Disable is set to "Enable", the following changes are effective.
The set value after change is reflected to the next automatic tuning.
Only when this property value is changed to "Set Response Time", the property of Target Response Time (msec) can be set.
The property value can be changed only when "Set Response Time" is specified for Automated QoS:Priority.
When the property value is changed from Off to On, this operation is collaborated with Automated Storage Tiering from the next execution of automatic tuning.
When the property value is changed from On to Off, this operation is not collaborated with Automated Storage Tiering from the next execution of automatic tuning.
Point
When enabling Automated QoS for a Virtual Volume, change the settings of performance management so that the Virtual Volume is monitored by this product. Refer to "Instruction for Performance Management" in the Storage Cruiser Operation Guide for the method for changing settings.
When managing virtual machines with this product according to a policy designed by storage administrators, specify "Any" for Automated QoS Enable/Disable and change the policy.
Settings can be changed. The chanted settings are immediately reflected.
Point
When managing virtual machines with this product according to a policy designed by storage administrators, specify "Any" for Extreme Cache and change the policy.
Settings cannot be changed.
