[Qualification]: Support Confirmation for sci-unity version 2.15.0 on Kubernetes v1.32.9+rke2r1

  • OS: RHEL 8.10

  • Orchestrator: RKE2 v1.32.9+rke2r1

  • Storage Platform: EMC Unity 480F

  • Attachments: How to upload files?

  • Additional details: both kubernetes e2e and csi-cert have been ran

Documented Test Exclusions & Configurations

Due to our specific infrastructure requirements and known driver bugs, several standard cert-csi tests have been explicitly disabled:

  1. Volume Cloning & Snapshots (clone: falsesnapshot: false):

    • Reason: Skipped due to our strict company policy requiring Thick Provisioning (thinProvisioned: "false"). Dell Unity's CSI Volume Cloning and Snapshot capabilities fundamentally require underlying array-level snapshots, which mandate Thin Provisioning. Testing thick clones will always result in array-level rejection.

  2. NFS Suites:

    • Reason: Skipped (the nfs-storage block was removed from the config). Our environment exclusively uses Fibre Channel (FC). Leaving the default NFS template in the configuration will cause the EphemeralVolumeSuite to time out and fail.

  3. Raw Block Expansion (Potential Issue):

    • Reason: While standard filesystem expansion is supported, expanding Raw Block volumes may fail with a NodeResizeError. This is an OS-integration bug where the Dell Unity CSI Node Plugin attempts to execute multipathd resize map using the raw WWN, but fails to prepend the required NAA 3 prefix that RHEL expects.

References for Excluded Raw Block Tests:
The multipathd resize map failure during raw block expansion is caused by the CSI Node Plugin omitting the SCSI NAA designator prefix (3) from the Unity WWN.

  • Dell Host Connectivity Guide: Acknowledges that RHEL identifies Unity LUNs with the 3 prepended to the WWN (See: Dell Unity XT Linux Setup).

  • RHEL/Linux Storage Standards: Documents that scsi_id prepends the 3 to comply with the NAA designator type in VPD page 0x83 (See: Persistent Identifiers for Storage).
