vi IBM System Storage N series: Data ONTAP 8.1.2 Release Notes for 7-Mode
Data ONTAP 8.1.2 for 7-Mode Release Notes These Release Notes describe new features, enhancements, and known issues for this release of Data ONTAP, as well as additional information related to running this release on specific storage systems. About the Data ONTAP 8.1.2 release Data ONTAP 8.1.2 is a General Availability (GA) release and the second maintenance release in the Data ONTAP 8.1.x release family. For more information about Data ONTAP releases, refer to the following publication: IBM System Storage N series Data ONTAP Release Model For up to date information regarding the latest release of Data ONTAP, refer to the following publication: If you are upgrading to this Data ONTAP release or reverting from this release to an earlier release, see the Data ONTAP Upgrade and Revert/Downgrade Guide for 7-Mode. Attention: If you have an N6210 or an N6040 storage system with Flash Cache modules, Data ONTAP 8.1.2 reenables the 256-GB Flash Cache module on the N6210 or N6040 storage systems using the full capacity for wear-leveling and cache storage. However, to deliver on the full value of Data ONTAP 8.1.2, the maximum working dataset in the 256-GB Flash Cache module on N6210 or N6040 storage systems is 128 GB. For more information, see “N6210 series and N6040 series storage systems with Flash Cache modules are supported” on page 110.
