Multi-Disk SQL Server Service Template

Hi All,

I have a VM Template with multiple disks which I'm planning to use in a service template containing a SQL Profile.

When building a VM from this image, the 2nd & 3rd disks are always offline.  I've created a diskpart script to bring the disks online.  What's the best way to ensure that this script runs prior to the SQL Server customisation being applied?

It's VMM 2012 R2 & the guest OS is Win 2012 R2 with SQL Server 2012SP1

Thanks
