NetApp Essentials Bundle

NetApp says that Snapshot is included into Essentials Bundle.

But how to create snapshots from SAN LUN's if there is no snapdrive?

Any ideas? Without stopping the LUN and taking snaps.

Regars,

Re: NetApp Essentials Bundle

You can script pretty much any OS to flush the buffers to disk & then take a snapshot on the filer - SnapDrive does the same thing.

Re: NetApp Essentials Bundle

Is that any example available for Windows Server?

Hi,

Have a look at NetApp DataONTAP PowerShell Module for the NetApp part:

Vssadmin command can be used for creating VSS snapshot at the OS layer, followed by NetApp snapshot. An example here:

Radek,

         It is possible to take snapshots, but what if i have to restore something from that LUN? Am I able to map this "Snap"LUN to windows? Without flexclone and snaprestore.

Re: NetApp Essentials Bundle

Yes - see “lun clone”.

Re: NetApp Essentials Bundle

So i have to wait the time to copy all blocks of a 2TB lun?

Is that only one way? Is that possible to map the LUN without clone it?

Re: NetApp Essentials Bundle

LUN clone is a "thin copy" operation, like FlexClone.
