Manage volumes

Contributors netapp-pcarriga netapp-dbagwell amgrissino

Using the NetApp Element Plug-in for VMware vCenter Serverr, you can create, view, edit, delete, clone, backup or restore volumes for user accounts. You can also manage each volume on a cluster, and add or remove volumes in volume access groups.

Options

Create a volume

You can create a new volume and associate the volume with a given account (every volume must be associated with an account). This association gives the account access to the volume through the iSCSI initiators using the CHAP credentials. You can also specify QoS settings for a volume during creation.

VMware requires 512e for disk resources. If 512e is not enabled, a VMFS cannot be created.

What you'll need

  • At least one cluster must be added and running.

  • A user account has been created.

Steps

  1. From the vCenter Plug-in, open the Management tab:

    • Beginning with Element vCenter plug-in 5.0, select NetApp Element Remote Plugin > Management > Management.

    • For Element vCenter plug-in 4.10 and earlier, select NetApp Element Management > Management.

  2. If two or more clusters are added, select the cluster you intend to use for the task in the navigation bar.

  3. Select the Volumes sub-tab.

  4. From the Active view, select Create Volume.

  5. Enter a name for the volume.

    Tip Use descriptive naming best practices. This is especially important if multiple clusters or vCenter Servers are used in your environment.

  6. Enter the total size of the volume you want to create.

    Note The default volume size selection is in GB. You can create volumes using sizes measured in GB or GiB:
    1GB = 1 000 000 000 bytes
    1GiB = 1 073 741 824 bytes
    Note By default, 512 byte emulation is set to ON for all the new volumes. VMware requires 512e for disk resources. If 512e is not enabled, a VMFS cannot be created.

  7. Select a user account from the Account list.

  8. In the Quality of Service area, do one of the following:

    • Under Policy, select an existing QoS policy, if available.

    • Under Custom Settings, set customized minimum, maximum, and burst values for IOPS or use the default QoS values.

      Important QoS policies are best for service environments, for example, with database, application, or infrastructure servers that rarely reboot and need constant equal access to storage. Custom QoSSIOC automation is best for light use VMs, such as virtual desktops or specialized kiosk-type VMs, that may be rebooted, powered on, or powered off daily or several times a day. QoSSIOC automation and QoS policies should not be used together.
      After you enable datastore QoSSIOC settings, any QoS settings at the volume level are overridden.
      Volumes that have a Max or Burst IOPS value greater than 20,000 IOPS might require high queue depth or multiple sessions to achieve this level of IOPS on a single volume.

  9. Select OK.

View volume details

You can review general information for all active volumes on the cluster in the plug-in extension point. You can also see details for each active volume, including efficiency, performance, QoS, as well as associated snapshots.

  • Max Bandwidth: The maximum bandwidth permitted by the system to process larger block sizes.

Snapshots section

  • Snapshot ID: System generated ID for the snapshot.

  • Snapshot Name: User-defined name for the snapshot.

  • Create Date: The date and time at which the snapshot was created.

  • Expiration Date: day and time the snapshot will be deleted.

  • Size: User-defined size of the snapshot in GB.

Edit a volume

You can change volume attributes such as QoS values, volume size, and the unit of measurement in which byte values are calculated. You can also change access levels and which account can access the volume. You can also modify account access for replication usage or to restrict access to the volume.

If you are using persistent volumes with the management node, do not modify the names of the persistent volumes.

Steps

  1. From the vCenter Plug-in, open the Management tab:

    • Beginning with Element vCenter plug-in 5.0, select NetApp Element Remote Plugin > Management > Management.

    • For Element vCenter plug-in 4.10 and earlier, select NetApp Element Management > Management.

  2. If two or more clusters are added, select the cluster in the navigation bar.

  3. Click the Volumes subtab.

  4. From the Active view, check the volume.

  5. Select Actions.

  6. Select Edit.

  7. Optional: In the Volume Size field, enter a different volume size in GB or GiB.

    Note You can increase, but not decrease, the size of the volume. If you are adjusting volume size for replication, you should first increase the size of the volume assigned as the replication target. Then you can resize the source volume. The target volume can be greater or equal in size to the source volume, but it cannot be smaller.

  8. Optional: Select a different user account.

  9. Optional: Select a different access level of one of the following:

    • Read/Write

    • Read Only

    • Locked

    • Replication Target

  10. In the Quality of Service area, do one of the following:

    • Under Policy, select an existing QoS policy, if available.

    • Under Custom Settings, set customized minimum, maximum, and burst values for IOPS or use the default QoS values.

      Tip Best Practice: When you change IOPS values, use increments in tens or hundreds. Input values require valid whole numbers.
      Configure volumes with an extremely high burst value. This allows the system to process occasional large block sequential workloads more quickly, while still constraining the sustained IOPS for a volume.
      Important

      QoS policies are best for service environments, for example, with database, application, or infrastructure servers that rarely reboot and need constant equal access to storage. Custom QoSSIOC automation is best for light use VMs, such as virtual desktops or specialized kiosk-type VMs, that may be rebooted, powered on, or powered off daily or several times a day. QoSSIOC automation and QoS policies should not be used together.

      After you enable datastore QoSSIOC settings, any QoS settings at the volume level are overridden.

      Volumes that have a Max or Burst IOPS value greater than 20,000 IOPS might require high queue depth or multiple sessions to achieve this level of IOPS on a single volume.

  11. Select OK.

Clone a volume

You can create a clone of a volume to make a point-in-time copy of the data. When you clone a volume, the system creates a snapshot of the volume and then creates a copy of the data referenced by the snapshot. This is an asynchronous process, and the amount of time the process requires depends on the size of the volume you are cloning and the current cluster load.

What you'll need

  • At least one cluster must be added and running.

  • At least one volume must be created.

  • At least one user account must be created.

  • Available unprovisioned space must be equal to or more than the source volume size.

About this task

The cluster supports up to two running clone requests per volume at a time and up to 8 active volume clone operations at a time. Requests beyond these limits are queued for later processing.

Note Cloned volumes do not inherit volume access group membership from the source volume.

Operating systems differ in how they treat cloned volumes. ESXi will treat a cloned volume as a volume copy or snapshot volume. The volume will be an available device to use to create a new datastore. For more information on mounting clone volumes and handling snapshot LUNs, see VMware documentation about mounting a VMFS datastore copy and managing duplicate VMFS datastores.

Steps

  1. From the vCenter Plug-in, open the Management tab:

    • Beginning with Element vCenter plug-in 5.0, select NetApp Element Remote Plugin > Management > Management.

    • For Element vCenter plug-in 4.10 and earlier, select NetApp Element Management > Management.

  2. If two or more clusters are added, select the cluster in the navigation bar.

  3. Check the volume you want to clone.

  4. Select Actions.

  5. Select Clone.

  6. Enter a volume name for the newly cloned volume.

    Tip Use descriptive naming best practices. This is especially important if multiple clusters or vCenter Servers are used in your environment.

  7. Select a size in GB or GIB for the cloned volume.

    The default volume size selection is in GB. You can create volumes using sizes measured in GB or GiB:

    • 1GB = 1 000 000 000 bytes

    • 1GiB = 1 073 741 824 bytes

      Increasing the volume size of a clone results in a new volume with additional free space at the end of the volume. Depending on how you use the volume, you may need to extend partitions or create new partitions in the free space to make use of it.

  8. Select an account to associate with the newly cloned volume.

  9. Select the one of the following access types for the newly cloned volume:

    • Read/Write

    • Read Only

    • Locked

  10. Adjust 512e settings, if required.

    Note By default, 512 byte emulation is enabled for all new volumes. VMware requires 512e for disk resources. If 512e is not enabled, a VMFS cannot be created and volume details are grayed out.

  11. Select OK.

    Note The time to complete a cloning operation is affected by volume size and current cluster load. Refresh the page if the cloned volume does not appear in the volume list.

Back up or restore volumes

You can configure the system to back up and restore the contents of a volume to and from an object store container that is external to NetApp Element software-based storage.

You can also back up and restore data to and from remote NetApp Element software-based systems. You can run a maximum of two backup or restore processes at a time on a volume.

Delete volumes

You can delete one or more volumes from a NetApp Element cluster using the plug-in extension point.

The system does not immediately purge a deleted volume. A deleted volume can be restored for approximately eight hours.

You can restore a volume before the system purges it or manually purge the volume from the Deleted view in Management > Volumes. When you restore a volume, it comes back online and iSCSI connections are restored.

Important Persistent volumes that are associated with management services are created and assigned to a new account during installation or upgrade. If you are using persistent volumes, do not modify or delete the volumes or their associated account.
Important If a volume used to create a snapshot is deleted, its associated snapshots are listed in the Inactive view on the Protection > Snapshots page. When the deleted source volumes are purged, the snapshots in Inactive view are also removed from the system.
Steps

  1. From the vCenter Plug-in, open the Management tab:

    • Beginning with Element vCenter plug-in 5.0, select NetApp Element Remote Plugin > Management > Management.

    • For Element vCenter plug-in 4.10 and earlier, select NetApp Element Management > Management.

Purge volumes

You can manually purge volumes after you have deleted them.

The system automatically purges deleted volumes eight hours after deletion. However, if you want to purge a volume before the scheduled purge time, you can perform a manual purge using the following steps.

Important When a volume is purged, it is immediately and permanently removed from the system. All data in the volume is lost.
Steps

  1. From the vCenter Plug-in, open the Management tab:

    • Beginning with Element vCenter plug-in 5.0, select NetApp Element Remote Plugin > Management > Management.

    • For Element vCenter plug-in 4.10 and earlier, select NetApp Element Management > Management.

  2. If two or more clusters are added, select the cluster in the navigation bar.

  3. Select the Volumes subtab.

  4. Select the view filter and select Deleted from the list.

  5. Select one or more volumes you want to purge.

  6. Select Purge.

  7. Confirm the action.

Restore deleted volumes

You can restore a volume in the NetApp Element system if it has been deleted but not yet purged.

The system automatically purges a volume approximately eight hours after it has been deleted. If the system has purged the volume, you cannot restore it.

Note If a volume is deleted and then restored, ESXi will not detect the restored volume (and datastore if it exists). Remove the static target from the ESXi iSCSI adapter and rescan the adapter.
