When provisioning storage in a SAN environment, there are several best practices you should follow to ensure that your systems run smoothly.
You should follow these guidelines when creating traditional or FlexVol volumes that contain LUNs, regardless of which provisioning method you choose:
Data ONTAP uses this volume to administer the storage system. The default root volume is /vol/vol0.
If this is not possible and you are storing LUNs and files in the same volume, you can use a separate qtree to contain the LUNs.
This is a recommended best practice that simplifies LUN administration and tracking.
You can change the snapreserve setting for the volume to 0, set the snap schedule so that no controller-based Snapshot copies are taken, and delete all Snapshot copies after you create the volume.
For more information about creating volumes, see the Data ONTAP Storage Management Guide for 7-Mode.
