We're using DPM 2010 for exchange backups,
The backup Disk(s) are iSCSI attached drives from multiple NAS boxes.
We'd like to mirror iqn.2009-07.com.example.example:RAID.iscsi4.vg0.iscsi05
onto iqn.2012-3.com.example.example:RAID.iscsi4.vg0.iscsi05
DPM 2010 requires the disk for itself and handles volume creation, Therefore we can't just create a mirrored volume in Disk Management. DPM itself doesn't seem to have any ability to mirror the Disks in its storage pool.
The disks are initiated using the Windows-server-2008 iSCSI Initiator, the two iSCSI drives are on seperate NAS boxes (one of which will soon be down for maintenance)
Any tips on how to mirror the volumes from one drive to the other?
