Accordind to Veeam DD OS 5.4 and later with dd boost 3.0 is supported with B&R 9.0. Using it through IP is working fine, Using it through fiber channel return "DD OS Version 5,4 or later is required to use dd boost", so it is not working.
on the data domain dd boost over FC is enabled and access group was created.
the DD is also used as VTL for another backup system through fibre channel.
I have read on DD with VTL best practice that the fibre channel port should be dedicated to VTL.
Can someone confirm we cannot used the DD domain for both VTL through FC and DD boost through FC ( with or without Veeam B&R) ?
