Description -

When configuring a StorageClass to use the new GCP Hyperdisk Balanced High Availability storage, the provisioning fails immediately. The internal validation logic within the Red Hat build of the CSI driver rejects the parameter hyperdisk-balanced-high-availability as an invalid disk type.

It appears the downstream driver needs to be rebased or patched to match upstream capabilities that support the Hyperdisk family.

Error -

failed to provision volume with StorageClass "balanced-ha-storage":
rpc error: code = InvalidArgument
desc = failed to extract parameters: parameters contain invalid disk type hyperdisk-balanced-high-availability

Expected Results -

The CSI driver should validate the hyperdisk-balanced-high-availability type successfully and provision the volume on GCP.

Business Impact - 

• Performance:  Customers are unable to utilize Google's latest storage tier (Hyperdisk) which offers significantly higher IOPS and throughput compared to legacy PD-SSD.
