Creating FlexCache volumes

You use FlexCache volumes to speed up access to remote data, or to offload traffic from heavily accessed volumes.

Before You Begin

Step

1. Enter the following command:vol create cache_vol aggr [size{k|m|g|t}] -S origin:source_vol

   origin is the name or IP address of the origin system. If you use the name, then changing the IP address of the origin system does not affect the FlexCache volume.

   cache_vol is the name of the new FlexCache volume you want to create.

   aggr is the name of the containing aggregate for the new FlexCache volume.

   size{ k | m | g | t } specifies the FlexCache volume size in kilobytes, megabytes, gigabytes, or terabytes. If you do not specify a unit, size is taken as bytes and rounded up to the nearest multiple of 4 KB.

   Note: For best performance, do not specify a size when you create a FlexCache volume. Specifying a size disables the FlexCache Autogrow capability.

   source_vol is the name of the volume you want to use as the origin volume on the origin system.

   The new FlexCache volume is created and an entry is added to the /etc/export file for the new volume.
