Using Named Disks and Reviewing Storage Policies

You can create and manage named disks, and review the organization virtual data center storage policies by using the Cyfuture Cloud Console tenant portal.

This chapter includes the following topics:

Creating and Using Named Disks

Review Storage Policy Properties

Creating and Using Named Disks

Named disks are standalone virtual disks that you create in Organization VDCs. Organization administrators and users who have the respective rights can create, remove, and update named disks, and connect them to virtual machines.

When you create a named disk, it is associated with an Organization VDC but not with a virtual machine. After you create the disk in a VDC, the disk owner or an administrator can attach it to any virtual machine deployed in the VDC. If you have the Create a Shared Disk right, you can create a shared named disk that you can attach to multiple VMs. The disk owner can also

modify the disk properties, detach it from a virtual machine, and remove it from the VDC. System administrators and organization administrators have the same rights to use and modify the disk as the disk owner.

Note  Although vSphere supports configurations like Windows Server Failover Cluster (WSFC) and you can create a shared disk through physical SCSI bus sharing, Cyfuture Cloud Console 10.2 does not support this feature. When creating a shared disk in Cyfuture Cloud Console, you only create an underlying independent persistent disk in vSphere with multiwriter mode enabled.

If you attach a named disk, you cannot take VM snapshots. If a shared disk is attached to a VM, you cannot edit its hard disk setting from the VM details view.

If the organization VDC has a storage policy with enabled VM encryption, you can encrypt VMs and disks by associating them with storage policies that have the VM Encryption capability. See Virtual Machine Encryption.

Create a Named Disk

You can create a named disk and attach it to one or more virtual machines at a later stage.

To create a named disk, you must specify its name and size. You can optionally include a description and select a storage profile to be used by the disk. You can create a shared disk that you can attach to multiple VMs.

Note  Although VMWare vSphere supports configurations like Windows Server Failover Cluster (WSFC) and you can create a shared disk through physical SCSI bus sharing, Cyfuture Cloud Console 10.2 does not support this feature. When creating a shared disk in Cyfuture Cloud Console, you only create an underlying independent persistent disk in vSphere with multiwriter mode enabled.

Prerequisites

  1. You must have an organization administrator role or disk owner rights.
  2. If you want to create a shared disk, you must have the Create a Shared Disk right.

Procedure

  1. On the Virtual Data Center dashboard screen, click the card of the virtual data center you want to explore and under Storage, from the left panel, select Named Disks.
  2. Click New.
  3. Enter a name and, optionally, a description of the disk.
  4. Select the storage policy from the Storage Policy drop-down menu.
  5. Enter the size of the named disk.
  6. Select the bus type and subtype, from the Bus Type and Bus Sub-Type drop-down menus, respectively.
  7. If you want to attach the named disk to multiple VMs, select the Shareable check box. You cannot edit this setting later.
  8. Click Save.

What to do next

Use the Cyfuture Cloud Console API to attach the independent disk to a virtual machine. See

Cyfuture Cloud Console API Programming Guide on Cyfuture Cloud {code}.

Edit a Named Disk

After you have created the disk, you can modify its name, description, storage policy, and size. You cannot edit the Shareable setting of a named disk.

Prerequisites

1 You must have an organization administrator role or disk owner rights.

Procedure

  1. On the Virtual Data Center dashboard screen, click the card of the virtual data center you want to explore and under Storage, from the left panel, select Named Disks.
  2. Select the disk you want to modify, and click Edit.
  3. Edit the settings such as name, description, storage policy, and size.
  4. Click Save.

Attach a Named Disk to a Virtual Machine

After you create a named disk in a VDC, you can attach it to any virtual machine that is deployed in the VDC. You can attach a shared named disk to multiple VMs.

Prerequisites

You must have an organization administrator role or disk owner rights.

Procedure

  1. On the Virtual Data Center dashboard screen, click the card of the virtual data center you want to explore and under Storage, from the left panel, select Named Disks.

  2. Click the radio button next to the name of the named disk that you want to attach to a virtual machine, and click Attach.

  3. From the drop-down menu, select a virtual machine to which to attach the named disk, and click Apply.

  4. If you want to attach another VM to a shared disk, repeat Step 2 and Step 3. 

What to do next

You can attach more named disks to the VM or detach them as needed.

Delete a Named Disk

If you don't need a named disk, you can delete it.

Prerequisites

You must have an organization administrator role or disk owner rights.

Procedure

  1. On the Virtual Data Center dashboard screen, click the card of the virtual data center you want to explore and under Storage, from the left panel, select Named Disks.
  2. Select the disk you want to delete, and click Delete.
  3. Click OK.

Review Storage Policy Properties

You can review the storage policies and storage policy details.

Prerequisites

This operation requires the rights included in the predefined Organization Administrator role or an equivalent set of rights.

Procedure

  1. On the Virtual Data Center dashboard screen, click the card of the virtual data center you want to explore.
  2. Under Storage, click Storage Policies.The list of the available storage policies displays.
  3. To view the details about a storage policy, click the name of the storage policy.
  4. Review the details on the General and Metadata tabs, and click OK.

 You can review the name, limit, IOPS settings, and metadata details of the storage policy.
