The current FlexCache license, flex_cache, has been replaced by a new license, flexcache_nfs. The old license is supported for the Data ONTAP 7.2 release family, but is no longer supported for Data ONTAP 7.3 and later. See your sales representative Contact your IBM N series support representative to obtain and install the new flexcache_nfs license if it is not already present on your system.

Attention: If you upgrade to Data ONTAP 7.3 or later and the new license is not installed, you will not be able to access data in FlexCache volumes after the upgrade. As soon as you install the new license, the FlexCache data will become accessible.
