Feature Request: Support for IBM Policy‑Based HA (PBHA) Volumes in Veeam Backup & Replication

[5c1eab04]

(case ID: 07989457)

Summary
IBM Policy‑Based HA (PBHA) volumes are currently not supported in the latest version of Veeam Backup & Replication. This limitation prevents successful storage‑integration workflows in PBHA environments and blocks snapshot‑based backup operations.
This request specifically concerns IBM FlashSystem FS7300.

[Moderator: Added link to relevant restriction in Veeam User Guide]

Technical Background
In PBHA configurations, such as those used with IBM FlashSystem FS7300, volumes and volume groups are managed within defined storage partitions. During snapshot or clone creation initiated by Veeam’s storage‑integration process, the newly created volume group may be assigned to a different storage partition than the host system.

This mismatch leads to host‑mapping failures, typically accompanied by errors such as:

CMMVC1034E ... same storage partition ...

As a result, the snapshot volumes cannot be exported or mounted, effectively preventing the use of storage‑integrated backups or restores in PBHA environments.

Business Impact
IBM is one of the leading enterprise storage vendors globally, as reflected in the Gartner Magic Quadrant 2025. The FlashSystem family — including the FS7300 — is widely deployed in modern enterprise environments, particularly in high‑availability and multi‑site scenarios where PBHA is a key architectural component.

The lack of PBHA support in Veeam Backup & Replication therefore affects a significant number of enterprise customers and limits the adoption of Veeam’s storage‑integration capabilities in IBM‑based infrastructures.

Request
We kindly request the implementation of full support for IBM Policy‑Based HA (PBHA) volumes — specifically including IBM FlashSystem FS7300 — in Veeam Backup & Replication, with the following enhancements:

Correct handling of PBHA storage partitions during snapshot/clone creation

Ensuring that newly created volume groups inherit the correct storage‑partition assignment

Reliable host mapping and export/mount operations for snapshot volumes

Given IBM’s market position and the prevalence of PBHA in enterprise deployments, this should be considered an urgent enhancement.

Thanks & Best Regards

Hi, thanks for the feedback. Storage integrations are implemented by the vendors via the USAPI framework provided by Veeam. As of now, IBM is responsible for implementing PBHA support in the USAPI plug-in they recently took over from Veeam, and our understanding is that this is their top priority.
