Before installing IBM FlashSystem Plug-In v2.0.26, ensure that you are running Veeam Backup & Replication 12.2.0.334 or higher. You can check the build number in the Veeam Backup & Replication Console's Main Menu (≡) under Help > About.

IBM FlashSystem Plug-In v2.0.26 supports integration with the following storage systems:

• IBM FlashSystem (formerly Spectrum Virtualize, includes IBM StorWize and IBM SVC) running IBM Spectrum Virtualize OS version 8.2 or later

Follow detailed instructions on configuring the IBM FlashSystem Plug-in and the storage system in the Veeam Backup & Replication Storage System Snapshot Integration Guide: Configuring Storage Systems.

This independent plug-in implements a full functionality set previously built into Veeam Backup & Replication.
For details, please review: Veeam Backup & Replication Storage System Snapshot Integration Guide: VMware Integration.

The following is a list of known major issues for IBM FlashSystem Plug-In for Veeam Backup & Replication.

For IBM Spectrum Virtualize 8.4.2 and later with iSCSI connectivity:

• During backup from storage snapshots and storage rescan, storage snapshot export to a proxy is required. If the default proxy is used, Veeam Backup & Replication creates a service host with the "VeeamAUX" prefix in the default portset of the storage system. If you want to send traffic using a custom portset, you can manually specify the required portset in the service host settings. If another proxy is used, check that the host that performs the proxy role has the required portset in the host settings.

For IBM Spectrum Virtualize 8.5.0 and earlier:

• Before adding the storage system to the backup infrastructure, ensure that a license for the IBM Spectrum Virtualize storage system supports IBM FlashCopy.

For IBM Spectrum Virtualize 8.5.1 and later:

• Volume snapshot functionality can cause node warmstarts on IBM Spectrum Virtualize 8.5.1 and later. This issue occurs if the account used to connect to the storage system in Veeam Backup & Replication is a member of an ownership group on the storage system. The problem is due to a known IBM issue (SVAPAR-138214).
  To avoid warmstarts, use an Administrator account that is not a member of the ownership group. Alternatively, you can switch to IBM FlashCopy by setting a registry value. For more information, contact Veeam Customer Support.
• Veeam Backup & Replication automatically uses storage volume snapshot technology, which does not require license support for IBM FlashCopy. Within the FlashSystem 5000 family, only the FlashSystem 5045 model supports the new storage volume snapshot technology.
  
  Once a storage volume snapshot is created (with or without Veeam Backup & Replication), FlashCopies—including policy-based Safeguarded backups created with third-party software—are blocked from being created. However, it remains possible to restore from previously created FlashCopies. If needed, you can continue working with FlashCopy by setting a registry value available from Veeam Customer Support. Note that setting this registry value would require removing all storage volume snapshots.
