Multiple Disk VM Provisioning

This chapter contains the following sections:

About Multiple Disk VM Provisioning

Cisco UCS Director supports virtual machine (VM) provisioning of multiple disks from a template. You can configure VM disk provisioning on a preferred single datastore or on multiple datastores. You can also configure individual disk policies for each additional disk in a template.

Cisco UCS Director classifies the disks into the following categories:

  • System

  • Data

  • Database

  • Swap

  • Log


Note

The disk categories that are defined by Cisco UCS Director are for disk labeling only.

Overview of the Procedure for Multiple Disk VM Provisioning

Procedure

Step 1

Check for the availability of a template with multiple disks.

Step 2

Assign disk categories.

Step 3

Define the storage policy.

Step 4

Create the template catalog.

About Templates with Multiple Disks

To provision a multiple disk virtual machine (VM), a template (image) with multiple disks, must be available. Before using a template with multiple disks for VM provisioning, you must assign the disk categories for individual disks.

Assigning Disk Categories

Procedure

Step 1

Choose Virtual > Compute.

Step 2

On the Compute page, choose the cloud.

Step 3

On the Compute page, click Images.

Step 4

Click the row with a template with multiple disks and click View Details.

Step 5

Click Disks.

Step 6

Choose a disk.

Step 7

Click the row with the disk for which you want to assign a disk type and click Assign Disk Type.

Step 8

On the Assign Disk Type screen, choose the disk type from the drop-down list.

It can be one of the following:

  • System

  • Data

  • Database

  • Swap

  • Log

Step 9

Click Submit.

Defining Storage Policies

A storage policy defines resources such as datastore scope, type of storage to use, minimum conditions for capacity, and latency. This policy also provides an option to configure additional disk policies for multiple disks, and an option to provide datastore choices for end users during a service request creation.

Cisco UCS Director supports VM provisioning with multiple disks on multiple datastores. There are five types of disks: System, Data, Database, Swap, and Log. The System disk policy is configured first, and the other disks are configured later depending on the requirements. You can configure the disk policy individually for each disk type, or choose the default system disk policy.

When using additional disk policies, be sure to uncheck the Provision all disks in a single datastore option during catalog creation for the multiple disk template. For more information about catalog creation, see Adding a Catalog.

In addition, Cisco UCS Director supports datastore selection during the creation of a service request for VM provisioning. It gives you an option to enable or disable datastore selection for the end user. When a VDC is specified at creation of a service request, the scope conditions defined in its storage policy determine which datastores appear for selection here.


Note

VMware VM provisioning fails when the datastore capacity specified in a storage policy uses the equals condition for decimal values with two values after the decimal (hundreths place). If specifying a capacity that includes decimal values, round the value up to one value after the decimal (tenths place).

See the Cisco UCS Director Troubleshooting Guide.

Creating a Storage Policy

Procedure

Step 1

Choose Policies > Virtual/Hypervisor Policies > Storage.

Step 2

On the Storage page, click VMware Storage Policy.

Step 3

Policy Description field

The description of the policy.

If you want to narrow the scope of deployment, choose whether to use all, include selected data stores, or exclude selected data stores.

Cloud Name drop-down list

Choose the cloud account for this resource allocation.

If you choose an SRM account, the Enable Protection check box is displayed. For more information about how to enable protection groups for Site Recovery Manager, see the Cisco UCS Director VMware Management Guide.

System Disk Scope

Use Linked Clone check box

If you want to use a linked clone, click the check box.

If you do not click this check box, the configuration uses a full clone.

Storage Profile drop-down list

Choose a storage profile if you want to provision one or more VMs with the associated storage profile.

Data Stores/Data Store Clusters Scope drop-down list

To define the scope of deployment, choose one of the following options:

  • All

  • Include Selected Datastores

  • Exclude Selected Datastores

  • Include Selected Datastore Clusters

  • Exclude Selected Datastore Clusters

Depending upon which option you choose, additional fields may display.

Note

 

The option that you choose determines which datastores or datastore clusters are available when you create a VM disk.

Selected Data Stores field

If you chose Include Selected Datastores or Exclude Selected Datastores, click Select to choose the appropriate datastores.

Use Shared Data Store Only check box

Click the check box to use shared datastores only.

This option is only available if you chose to include or exclude selected datastores.

Selected Datastore Clusters field

If you chose Include Selected Datastore Clusters or Exclude Selected Datastore Clusters, click Select to choose the appropriate datastore clusters.

Select SDRS Rule Type drop-down list

If you chose to include or exclude selected datastore clusters, choose one of the following SDRS rule types:

  • Keep VMDKs Together—You need to select an existing rule on the filtered clusters. The newly provisioned VM is added to the VM anti-affinity rule.

  • Separate VMDKs—If the newly provisioned VM contains more than one disk, a new VM affinity rule is created on the datastore cluster.

Select SDRS Rule field

If you chose Keep VMDKs Together, you must choose the VMs that you want to apply the rule to.

Storage Options

Use Local Storage check box

By default, the field is checked. Uncheck the check box if you do not want to use local storage.

Use NFS check box

By default, the field is checked. Uncheck the check box if you do not want to use NFS storage.

Use VMFS check box

By default, the field is checked. Uncheck the check box if you do not want to use VMFS storage.

Use SAN check box

By default, the field is checked. Uncheck the check box if you do not want to use SAN storage.

Filter Conditions check boxes

To add one more conditions to filter the datastores, do the following for each desired condition:

  • Click the appropriate check box.

  • Choose the desired option from the drop-down list.

  • Enter the criteria by which you want to filter the datastores.

Any datastores that do not meet these criteria are excluded from consideration. If more than one condition is chosen, all conditions must match.

Note

 

VMware VM provisioning fails when the datastore capacity specified in a storage policy uses the equals condition for decimal values with two values after the decimal (hundreths place). If specifying a capacity that includes decimal values, round the value up to one value after the decimal (tenths place).

For example if the value is 10.25 GB, it displays as 10.3 GB in the datastore report. For all options, you must specify any value less than 10.3 but rounded to one value after the decimal, such as 10.2 GB, 10.1 GB, or 10 GB.

Override Template check box

Check the check box to override the template properties. You are provided with options to enter custom settings, such as using thin provisioning or setting a custom disk size.

Use Thin Provisioning check box
