Using FlexShare to set volume buffer cache policy

You can use FlexShare to influence how Data ONTAP determines when to reuse buffers.

Steps

  1. If you have not already done so, ensure that FlexShare is enabled for your storage system by entering the following command:
    priority on
  2. Specify the cache buffer policy for the volume by entering the following command:
    priority set volume vol_name cache=policy

    policy is one of the following policy values:

    • keep
    • reuse
    • default

    Example

    The following command sets the cache buffer policy for the testvol1 volume to keep. This instructs Data ONTAP not to reuse the buffers for this volume when possible.

    priority set volume testvol1 cache=keep

  3. You can optionally verify the priority levels of the volume by entering the following command:
    priority show volume -v vol_name
