Creating Application Aware Snapshots in SAN/iQ 8.5

Prior to SAN/iQ 8.5, making snapshots application aware was a case of installing the required components and having a scheduled task on the guest running a script. Now there is a tick box in the Centralized Management Console to allow this.

Scenario:

Windows 2003 Server with SQL 2005 and iSCSI initiator installed, which has 3 volumes

i: O/S volume which is a vmdk
ii: iSCSI attached DATABASE volume
iii: iSCSI attached LOGS volume

The iSCSI volumes are presented on a LeftHand SAN/iQ 8.5 SAN

How to create application aware snapshots?

<< Note: I will go one step further and configure application aware snapshots with remote snapshots >>


1: Configuring the Windows Server components

i: On the Windows 2003 Server, do a typical install of the HP LeftHand Network Centralized Management Console for SAN/iQ 8.5


ii: On the Windows 2003 Server, install the HP LeftHand VSS Provider from the HP LeftHand P4000 Windows Solution Pack CD



2: Configuring the Authentication Console

On the Windows 2003 Server, Start > Programs > HP LeftHand Networks > Authentication Console

Enter the credentials for the Management Group in which your iSCSI volumes belong, Next > , Finish, then close the Authentication Console




3: Configuring the Snapshot with Remote Snapshot

In the HP LeftHand Networks Centralized Management Console, right-click the volume which holds your SQL data, and choose 'New Schedule to Remote Snapshot a Volume'


Configure like the below to your specifications << the important thing here is to tick the 'Application-Managed Snapshot' box, and create a new remote volume in the remote site for the database volume >>


When you click OK, it will retrieve information from the application server and discover the associated logs volume


Click Continue and create a new remote volume in the remote site for the logs volume


Click 'Create Schedule'

And that's it!


Note: SAN/iQ 9 will integrate with the VMware Virtual Center server so that you can create application aware snapshots of iSCSI VMFS volumes containing VMDKs

  1. This will not be available at SAN/iQ Version 9.0. All other updates will be available on the HP website.

  2. It does seem the VCENTER integration is NOT there.
    Too bad... as that would be a real Equallogic killer. Now, Dell still has an advantage with it's AutoSnapshot Manager / VMWare Edition
