The option defaults to on. In addition, SSL3 now includes 3DES as a supported cipher; this is the case whether TLS is enabled or not. Support for histogram-based predictions in RAVE Starting in Data ONTAP 8.2.1, the speculatie read-ahead engine (RAVE) in WAFL can capture additional temporal data about preious user read requests to a file and use this information to intelligently speculate on future read requests. In prior releases, speculation was based only on information from the current user I/O. You can enable or disable the use of histograms for storage systems operating in 7-Mode by using the wafl rae use_histogram <alue> command. A alue of 1 enables the feature and a alue of 0 disables it. For more information about performance data and the statistics commands, see the Data ONTAP System Administration Guide for 7-Mode. The system node serice-processor commands now support the RLM Starting with Data ONTAP 8.2.1, you can use the system node serice-processor commands to manage the Remote LAN Module (RLM) New and changed features in the Data ONTAP 8.2 release family for 7-Mode 19

28 from Data ONTAP. The rlm commands in the Data ONTAP CLI are deprecated in faor of the system node serice-processor commands. You can use the system node serice-processor commands to perform the following RLM management tasks: Set up or modify the RLM network configuration (system node serice-processor network modify) Display the RLM network configuration (system node serice-processor network show) Display the RLM information (system node serice-processor show) Reboot the RLM and optionally specify the RLM firmware image (primary or backup) to use (system node serice-processor reboot-sp) Display the details of the currently installed RLM firmware image (system node serice-processor image show) Update the RLM firmware (system node serice-processor image update) Display the status for the latest RLM firmware update (system node serice-processor image update-progress show) Licensing changes for the Data ONTAP 8.2 release family Data ONTAP 8.2 introduces licensing changes that affect how you manage the licenses of your storage system. The following licensing changes apply to the Data ONTAP 8.2 release family: How licensed features are mapped to packages has changed. Data ONTAP feature licenses are issued as packages, each of which contains multiple features or a single feature. A package requires a license key, and installing the key enables you to access all features in the package. For example, installing the key for the SnapManager Suite package on a system entitles the system to use all SnapManager products in the package. For information about the features that require licenses in the Data ONTAP 8.2 release family, see the knowledgebase article Data ONTAP 8.2 Licensing Oeriew and References. Data ONTAP no longer displays license states for indiidual features that are part of a license package; instead, Data ONTAP manages and displays entitlements at the license package leel. A standard Data ONTAP license, also known as a node-locked license, is issued for a system with a specific serial number and is not alid on other systems. Installing a standard, node-locked license entitles the system to the licensed functionality. The Data ONTAP 8.2 release family treats a license installed prior to Data ONTAP 8.2 as a standard license. Therefore, a system running Data ONTAP 20 IBM System Storage N series: Data ONTAP Release Notes For 7-Mode

29 8.2 or later automatically has the standard license for the package that the preiously licensed functionality is part of. The length of a license key has been increased to 28 characters. Licenses installed in a release earlier than Data ONTAP 8.2 continue to work after you upgrade to Data ONTAP 8.2 or later. Howeer, if you need to reinstall a license in Data ONTAP 8.2 or later (for example, you deleted a preiously installed license and want to reinstall it in Data ONTAP 8.2 or later, or you perform a controller replacement procedure for a system running Data ONTAP 8.2 or later), Data ONTAP requires that you enter the license key in the new, 28-character format. Note: If you wipe clean a system and reinstall it with a ersion that is earlier than Data ONTAP 8.2, you need to use a license key format that is supported for the release that you are installing. For information about how to obtain the license keys, see the knowledgebase article Data ONTAP 8.2 Licensing Oeriew and References. Starting with Data ONTAP 8.2, the following functionality no longer requires a license, but you might need to enable certain options before using it: High-aailability (HA) configurations You must set options cf.mode to ha. MetroCluster You must set options cf.mode to ha and then enable options cf.remote_syncmirror.enable. SyncMirror There is no option that you need to enable. If you replace or upgrade a controller that is running Data ONTAP 8.2 or later, within a grace period (up to 90 days) the new controller can use the same licensed functionality that the original controller had. During the grace period, you should contact your sales representatie to obtain a proper license key to install on the new controller. During the grace period when the first alid license key is installed, you hae 24 hours to complete license installation for all packages that you want the new controller to use. The grace period ends after the 24-hour period, and all preiously installed licenses that were associated with the original system serial number will be remoed from the new controller. Data ONTAP commands for managing licenses hae been enhanced. The license add command now enables you to add multiple license keys at a time. The license show command output has a different format and displays additional details. New and changed features in the Data ONTAP 8.2 release family for 7-Mode 21

30 For information about managing feature licenses, see the Data ONTAP System Administration Guide for 7-Mode. New command family for managing the SP from Data ONTAP Starting with Data ONTAP 8.2, the system node serice-processor commands are aailable for managing the Serice Processor (SP) from Data ONTAP. The sp and software install commands are deprecated in faor of the new commands. The system node serice-processor commands replace the sp commands for the following tasks: Set up or modify the SP network configuration (system node serice-processor network modify) Display the SP network configuration (system node serice-processor network show) Display the SP information (system node serice-processor show) Reboot the SP and optionally specify the SP firmware image (primary or backup) to use (system node serice-processor reboot-sp) Display the details of the currently installed SP firmware image (system node serice-processor image show) Enable or disable the SP automatic firmware update (system node serice-processor image modify) Manually update the SP firmware and specify the update settings (system node serice-processor image update) Display the status for the latest SP firmware update (system node serice-processor image update-progress show) In addition, the software install command is no longer supported for the SP firmware update. It is replaced by the system node serice-processor image update command. Enhancements for deliery of AutoSupport messages This release of Data ONTAP proides the new AutoSupport OnDemand feature, deliery of the fully qualified domain name (FQDN) to SMTP mail serers, and user space core reports in daily AutoSupport messages. AutoSupport OnDemand Starting in Data ONTAP 8.2, AutoSupport OnDemand is a new AutoSupport feature that ensures that technical support has the data it needs to proide quick incident resolution and preentie support. AutoSupport OnDemand periodically sends HTTPS requests to technical support to obtain deliery instructions. The deliery instructions can include 22 IBM System Storage N series: Data ONTAP Release Notes For 7-Mode

31 requests to generate new AutoSupport messages, retransmit preiously generated messages, and disable deliery of messages for specific trigger eents. The requests go to the same technical support location that AutoSupport messages are sent to. AutoSupport OnDemand is enabled by default. It automatically communicates with technical support if AutoSupport is configured to send messages to technical support and the transport protocol is HTTPS. For more information about AutoSupport OnDemand, see the Data ONTAP System Administration Guide for 7-Mode. FQDN deliery to SMTP mail serers Starting in Data ONTAP 8.2, when sending connection requests to SMTP mail serers, AutoSupport now specifies the FQDN of the node if DNS is configured. In preious releases, AutoSupport specified only the host name. Using the FQDN instead of the host name proides better compliance with mail protocol standards, such as RFC 2821 and Because it is best practice to configure mail serers to erify that the name proided by the client is a resolable FQDN and to reject the otherwise, this enhancement allows successful deliery of AutoSupport messages using SMTP. User space core reports Starting with Data ONTAP 8.2.1, when a user space application crashes and restarts, it produces a core dump and a core report. The core report was preiously collected as part of the weekly AutoSupport message. It is now collected as part of the daily AutoSupport message for management logs. The core dump itself can be uploaded separately, if desired. Enhancements to health monitoring The node connectiity health monitor in Data ONTAP 8.2 monitors SMB connections to ensure nondisruptie operations to Hyper-V applications. For more information about health monitoring, see the Data ONTAP System Administration Guide for 7-Mode. Messages in the /etc/messages file now include the system name Staring with Data ONTAP 8.2, messages in the /etc/messages file include the storage system name. This change helps administrators of multiple systems see which system a gien message came from. Options for specifying uppercase and lowercase requirements in user passwords Starting with Data ONTAP 8.2, you can specify the minimum number of uppercase or lowercase alphabetic characters that a password must contain. New and changed features in the Data ONTAP 8.2 release family for 7-Mode 23

32 You can use the following options to specify the requirements of uppercase or lowercase alphabetic characters in user passwords: The security.passwd.rules.minimum.uppercase option specifies the minimum number of uppercase alphabetic characters that a password must contain. The default is 0, which does not require that a password contain uppercase characters. The security.passwd.rules.minimum.lowercase option specifies the minimum number of lowercase alphabetic characters that a password must contain. The default is 0, which does not require that a password contain lowercase characters. High-aailability pair enhancements This Data ONTAP release includes new features and enhancements relating to HA pairs. Support for 16 Gb FC-VI adapters in a MetroCluster configuration Starting with Data ONTAP 8.2.1, the 16 Gb FC-VI adapter is supported with MetroCluster configurations. For more information about 16 Gb FC-VI adapters, see the Data ONTAP High Aailability and MetroCluster Configuration Guide for 7-Mode. Support for SSDs in a MetroCluster configuration Aggregates composed only of solid-state disks (SSDs) are supported in MetroCluster configurations. For more information about SSDs, see the Data ONTAP Storage Management Guide for 7-Mode. New cf.mode option replaces the cf license In Data ONTAP 8.2, the new cf.mode option replaces the requirement for the cf license. Support for unidirectional port mirroring in a MetroCluster configuration Starting with Data ONTAP 8.2.1, you can use unidirectional port mirroring in a MetroCluster configuration, which enables you to increase performance throughput by effectiely utilizing the FC-VI links in that MetroCluster configuration. To learn more about using unidirectional port mirroring, see the Data ONTAP High Aailability and MetroCluster Configuration Guide for 7-Mode. 24 IBM System Storage N series: Data ONTAP Release Notes For 7-Mode
