vm appli consistency with isilon and syncIQ

Hi,

IHAC with 2 isilon replicated with syncIQ (vmware datastore nfs).

Customer need VM application consistency at the target ( no crash constistency), so I would like to known how to get that

with Vipr and isilon syncIQ, as syncIQ is supported by Vipr Ctrl. Do I need to insert pre-script before syncIQ job in order

to freeze VMs ( for exampe with vmtools , a vsphere snap, then destroy this snap, as we do not need anymore ?)

Is it easy to insert pre-script in virp ctrl ?

thanks
