MSA2000 Snapshot initiated from OS

Is there an agent/sw available that initiate the snapshot from windows (not direct on the SAN Box).
We don't want to shutdown DB's etc on the host, before creating a snapshot.
I also tried the vss provider for the MSA but no success.

Hello,

why was the test with the VDS/ VSS Provider unsuccessful?

The VDS & VSS Provider for the MSA2000 should do what you're searching for.

Agree, the great thing with VSS is that it coordinates the requestor/writer/provider which is not done if you just initiate a snapshot on the array.

I would speed some time looking why VSS failed. Did work with it some time ago (not with a HP array) and I had to ask Microsoft for a hotfix.

Re: MSA2000 Snapshot initiated from OS

Thank you for your replies.

But how can I initiate a snapshot from the OS
Using commandline in win2008 is not support (works only for the builtin shadow copy). When I use BackupExec 12.5 I get the error "The provider has reported a storage identifier that is not supported by VSS"

What software product can initiate the snapshot on the MSA.

What does "vssadmin list providers" say?

Re: MSA2000 Snapshot initiated from OS

Good. Now, did you create a snap-pool on the MSA2000 and made sure the (MSA)volumes to be used are master (and not standard) volumes?

Hallo Uwe
thank you for your fast response!

Here the volume mapped to the win2008 hosts. And I am able to create a snapshot on the MSA.
