3.3.1 Creation of Policy

When creating a virtual machine or performing various types of operations, create the policies in advance.

The vSphere Web Client operating procedure is as follows:

Click VM Storage Policies from Home.
Click the Create a new VM storage policy icon.
Operate according to the directions on the screen.

Under Rule-Set, if "com.fujitsu.eternus" is selected as Rules based on data services, the Add rule pull-down menu is displayed. From the pull-down menu, add the desired function and specify a value for each function.

From Storage compatibility, the VVOL datastore that satisfies the created policy is displayed in Compatible storage. If the VVOL datastore is not displayed in Compatible storage, redo the Rule-Set operation.

Point

You can add the following functions under Add rule.
- Virtual Machine Backup
- Automated Storage Tiering (Advanced)
- Automated QoS (Advanced)
- Cache (Advanced)
- Security (Advanced)
Functions that are not added are set according the default value for that function.
If the VVOL datastore that is selected by the specified policy is configured in multiple Tier pools, the Virtual Volume is created in the Tier pool that has less Virtual Volumes than the others.

Note

Do not use Rules based on common capabilities or Rules based on tags.
Do not perform Add another rule set.

Policy Application and Applicable Scope

The policy applicable scope varies with the function.

Table 3.1 Policy Applicable Scope
Function	Policy Applicable Target
Virtual Machine Backup	Virtual machine
Automated Storage Tiering (Advanced)	Tier pool or Virtual Volume
Automated QoS (Advanced)	Virtual Volume
Cache (Advanced)	Virtual Volume
Security (Advanced)	Tier pool

When selecting storage to create a virtual machine (selecting a datastore in which to store a virtual machine file), in order to apply the policy, select the VM Storage Policies for which the policy satisfying the operational requirements is specified.
The policies excluding "Virtual Machine Backup" are applied when creating a virtual machine. Refer to "3.4.1 Creation of Virtual Machine" for creation of virtual machine.
The "Virtual Machine Backup" policy is applied when a virtual machine is powered on.

The following functions are automatically restarted by property settings when the policy has been completely applied.

Table 3.2 Target for Policy Automatic Start
Function	Property	Value
Virtual Machine Backup	Operation Mode	Auto
Automated Storage Tiering (Advanced)	-	-
Automated QoS (Advanced)	Automated QoS Enable/Disable	Enable
Cache (Advanced)	Extreme Cache	Any(*1), Enable
Security (Advanced)	Data encryption	Any(*2), Enable

Hyphen(-): Started regardless of property settings.
*1: When using the storage on which Extreme Cache or Extreme Cache Pool is installed.
*2: When using an encrypted Tier pool.

The backup operation of a virtual disk (Virtual Volume) connected to a virtual machine is performed according to the policy set up for the virtual machine.

Note

If applying the policy failed, automatic operation of "Virtual Machine Backup", "Automated Storage Tiering (Advanced)", or "Automated QoS (Advanced)" is not started. For this reason, after creating a virtual machine, check that the policy is properly applied.
Refer to "3.3.3 Confirmation of Policy Application" to check whether the policy is properly applied.
If the applied policy includes "Automated QoS (Advanced)", Automated QoS is started for only Virtual Volumes to be monitored. 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.

Policy Operating Condition

Policy settings (property value) and operating conditions are shown as follows.

Table 3.3 Settings (Property Value) and Operating Conditions in Policy

About Backup Targets

Backups are performed in each virtual machine. The backup targets are the virtual disks comprising the virtual machine.

To perform backups, the following conditions must be satisfied.

The datastore where the virtual machine configuration information is stored must be a VVOL datastore.
Select a VVOL datastore from "Selection storage" when creating a virtual machine.

All virtual machine disks comprising the virtual machine must be Virtual Volumes.

Virtual disks other than Virtual Volumes are not backup/restore targets depending on the type and settings.
Also, regardless of the virtual disk type, when a virtual disk is in Independent (Persistent/Nonpersistent) mode, it is not a target for backup/restore.
Refer to the below for details.

Table 3.5 Availability of Backup/Restore for Virtual Disk
Virtual Disk Type	Snapshot Backup, Restoration from Snapshot Backups	Clone Backup, Restoration From Clone Backups	Single Item Restore
Virtual Volume	Y	Y	Y
VMFS	Y	N	N

Y: Process target
N: Not the process target

Note

In restorations from a Clone backup, connection configuration for virtual disks that are excluded from a backup/restoration are not restored. Reconnect from VMware vCenter Server as necessary.
