We use SMHV for our backup solution for all our VM's and it works great!
Now we want to virtualize our SQL server. We created a VM and a couple off pass-through disks.
SMHV can't backup the machine because he has no access to the (luns) pass-through disks and the backup is Failed for all the VM's.
Ok, we installed Snapmanger for SQL and we make a backup and a mirror of the machine database. There is my point, no backup of the VM.
We want to separate the databases from CSV because we need seperate spindels for the databases and the VM's.
I did not try to make 5 new CSV volumes and put them in the cluster. Each new volume will have only one vhd file.
Those vhd files pointing to the SQL server and they are backuped with SMHV. But then I can not use SM for SQL because snapdrive (in the VM) does not see the luns?
So how can we make a good solution?
Solved! SEE THE SOLUTION

Even if a VM has one or more pass through disks attached to it, SMHV should be able to take backup of the VM successfully. The VM backup will not contain the data on pass through disks, but the backup itself should succeed and all the VHDs associated to the VM will be there in the backup.
A possible reason for failure of VM backup with pass through disks could be that the following hotfix is not installed:
Can you please check if this hotfix is installed on the Hyper-V parent?
If not, please install the hotfix on Hyper-V parent host and then update the integration services in each VM.

Thanks for your quick response!
The hotfix was already installed but there is nothing about pass-through disks.
I hope you have right that it is possible!
The error from microsoft eventlog is:

Once the hot fix is installed on the Hyper-V parent also remember to update the integration services in the VM
using following menu item
Action -> "Insert Integration Services Setup Disk".
[This will install the newer bits for the Integration packs inside the VM as a part of the Hotfix]
Retry the backup after the integration service is updated for the VM.
