9.10.1 RC1 (28 Nov 2021)

Cloud Volumes ONTAP 9.10.1 Release Candidate 1 is now available in AWS, Azure, and Google Cloud. This release includes the following new features and enhancements.

Reduced unplanned failover time

We reduced the unplanned failover time for Cloud Volumes ONTAP HA pairs running in Microsoft Azure.

NFSv4 support

NFSv4 is now supported with HA pairs running in Azure.

Security enhancements

We enhanced the security of ONTAP image creation and the security of the Cloud Volumes ONTAP boot disk.

Support for Keystone Flex Subscriptions

As part of the Cloud Manager 3.9.13 release, you can now use a Keystone Flex Subscription with Cloud Volumes ONTAP HA pairs. A Keystone Flex Subscription is a pay-as-you-grow subscription-based service that delivers a seamless hybrid cloud experience for those preferring OpEx consumption models to upfront CapEx or leasing.

A Keystone Flex Subscription is supported with all new versions of Cloud Volumes ONTAP that you can deploy from Cloud Manager.

Required version of the Cloud Manager Connector

The Cloud Manager Connector must be running version 3.9.13 or later to deploy new Cloud Volumes ONTAP 9.10.1 systems and to upgrade existing systems to 9.10.1.

Tip Automatic upgrades of the Connector are enabled by default so you should be running the latest version.

Upgrade notes

  • Upgrades of Cloud Volumes ONTAP must be completed from Cloud Manager. You should not upgrade Cloud Volumes ONTAP by using System Manager or the CLI. Doing so can impact system stability.

  • You can upgrade to Cloud Volumes ONTAP 9.10.1 from the 9.10.0 release and from the 9.9.1 release. Cloud Manager will prompt you to upgrade eligible Cloud Volumes ONTAP systems to the 9.10.1 release.

  • The upgrade of a single node system takes the system offline for up to 25 minutes, during which I/O is interrupted.

  • Upgrading an HA pair is nondisruptive and I/O is uninterrupted. During this nondisruptive upgrade process, each node is upgraded in tandem to continue serving I/O to clients.

c4, m4, and r4 instance types

Starting with the 9.8 release, c4, m4, and r4 instance types aren’t supported with new Cloud Volumes ONTAP systems. If you have an existing Cloud Volumes ONTAP system that’s running on a c4, m4, or r4 instance type, you can still upgrade to this release.

We recommend changing to an instance type in the c5, m5, or r5 instance family.


Starting with the 9.9.1 release, the DS3_v2 VM type is no longer supported with new and existing Cloud Volumes ONTAP systems. If you have an existing system running on this VM type, you’ll need to change VM types before you upgrade to 9.10.1.
