Customer of mine wants to use Provisioning Manager to provision volumes with standart values.
For example snapshot reserve 40% default snapshot schedule.
A littel but like System Manager is predefineing Nas/san volumes but flexible like the customer wants to set it.
Are there any best practices available?

Snap reserve is not configurable in a provisioning policy.
But user quotas and group quotas are configurable.
But there are requests to do the same.
Add your customer name to bug 358934 so it gets prioritized.

There are RFE to do these too 358935 , but today these options are not user configurable with Provisioning Manager.
But provisioning manger does set these options.

Currently the best way to do these options is to create a script (either ONTAPI with Perl etc. as I've done) or a shell script of some kind to set the options. This can then be set as a post-provision script to run once the setup has been completed. This is also a good place to add in any kind of mapping to the maintenance host etc. if you are in to that type of thing.

One clarification. Depending on the space settings of the ProvPolicy, fractional_reserve will be set at 0% or 100%, with autogrow and snap autodelete set as appropriate to trade off the risk of write failures against the space cost.
Out of curiosity, how'd they arrive at 40%? And what value for fractional_reserve did they want?
