Cisco Metacloud July 2017 Update (Metacloud version 4.5)

This 4.5 release of Cisco Metacloud contains bug fixes, feature updates, and an update to enable support of the Nimble storage driver.

Nimble Storage Driver

Note
The Nimble storage driver is currently available in a limited capacity, see Known Issues with the Nimble Storage Driver for more information.

The Nimble storage driver enables a host to configure and manage Nimble Storage array features using Block Storage interfaces.

Note
The Nimble storage driver uses iSCSI only. Fibre Channel is not supported.

The Nimble storage driver supports the following operations:

  • Create, delete, clone, attach, and detach volumes.
  • Create and delete volume snapshots.
  • Create a volume from a snapshot.
  • Copy an image to a volume.
  • Copy a volume to an image.
  • Extend a volume.
  • Get volume statistics.
  • Manage and unmanage a volume.

Known Issues with the Nimble Storage Driver

The following issues have been detected in certain edge-case tests:

  • When performing a bulk creation of volumes, some volumes were not able to attach to the VM.
  • After deleting a server, attached volumes may remain IN USE and cannot be deleted.
  • When performing a live migration of a compute instance, an instance may remain ACTIVE and not move to a new hypervisor.
