Release Information for Hitachi Plug-In for Veeam Backup & Replication

The following is a list of known major issues for Hitachi Plug-In for Veeam Backup & Replication. If you experience any issue listed below, please contact Hitachi support directly.

• Thin Image Advanced feature is only supported for volumes with DRS attribute. The attribute must be inherited to snapshots.
• When backing up a Global Active Device (GAD) volume, note that the copy group name to which the volume belongs must be prefixed with "VBR_" otherwise, backup jobs will fail. This requirement applies even if only one volume from a GAD replication relationship is added to a Veeam Backup & Replication instance.
• When adding Hitachi storage to the Veeam Backup & Replication infrastructure, the following addresses should be used:
  • For VSP One Block series, use the Service IP address.
  • For VSP 5000 series, use the Service Processor (SVP) IP.
  • For all other storage models, use one of the CTL1/CTL2 IP addresses.
• DNS names (hostnames/FQDNs) cannot be used to add the storage; only IP addresses are allowed. Additionally, IPv6 can only be used if the IPv4 management address is not configured on the storage.
• Hitachi Plug-In does not return information about volumes that are not mounted to a host. To restore from snapshots residing on such volumes, mount a volume to a host and perform a rescan in the Veeam Backup & Replication console. For details, see Rescanning Storage Systems.
• This plug-in version does not support Freeze-only snapshots. If you want to enable VM processing using VMware snapshots, contact Veeam support to change the value of a dedicated registry key.
• After deleting a snapshot, logical device (LDEV) records with the _DEL suffix may remain on storage until the subsequent automatic maintenance. However, such snapshots can occasionally be exported and displayed in the storage infrastructure UI as regular volumes if the storage rescan fails to purge them - in this case, they can be unexported or deleted manually.
  
• The same applies to clones that are purged during rescan only if synchronization between the source snapshot and its clone is not underway.
• Retention-based snapshot removal may fail if synchronization between the snapshot and its clone has not been completed or is still running.
• If jobs and rescan operations are running in parallel or at the moment when the storage system is processing other tasks, the operations may fail.
• Ensure at least two FC ports are available on the storage; configurations with a single FC port are not supported.
• Hitachi Plug-In does not support backing up failover clusters using Veeam Agent for Microsoft Windows.
