How to setup SAN access for use with Veeam Backup & Replication.


This Knowledge Base provides instruction on how to setup SAN access for use with Veeam Backup & Replication.


The instructions below describe how to setup SAN access for use with Veeam Backup & Replication.  It is very important you do not allow Windows to initialize any VMFS volumes you are presenting to it.

  1. Veeam Backup & Replication versions 5.X - 6.1 disable automount in Microsoft Windows Server automatically during installation, hence you do not need to do it manually.  Veeam Backup & Replication version 6.5 disables automount in the case of Windows versions 2003 and earlier, or will update the SAN Policy to "Offline shared" in Windows Server versions 2008 or newer.
  2. Confirm Veeam Backup is installed before you start connecting your backup server into the SAN fabric.
  3. If you are using Fibre Channel, first plug-in FC HBA into Veeam Backup server and install the latest drivers. Make sure that any client side settings needed for HBA to point to the storage are in place. This is typically documented by the storage vendor you are working with.
  4. In case of iSCSI storage, you will need to enter the iSCSI target IP in the initiator settings. This is typically Microsoft iSCSI initiator which is found under Administrative Tools in Microsoft Windows Server. Please see this post for further details and screenshots:
  5. Once connected, VMFS LUNs should appear in Windows Disk Management snap-in. They should be non-initialized without drive letters as Windows is not compatible with this file system.
