Note: This topic describes changes in this release that are specific to FilerView. For general changes in this release of Data ONTAP, see the Data ONTAP Release Notes.
FilerView changes since the previous release of Data ONTAP include the following:
Support added for role-based administrator access
You can perform tasks in FilerView according to the capabilities that have been granted to the roles assigned to the group(s) to which your user account belongs. For information about administrator access, groups, and roles, see the Data ONTAP System Administration Guide. If you are unable to exercise capabilities that you think you should be authorized to perform, see your system administrator.
Enhanced LUN Modify page
You can now use the Modify LUN page (LUNs > Manage > lun_name > Modify) to change the LUN path to another path in the same volume or qtree. You can also modify the LUN share option from this page.
New LUN Configuration Check page
The new LUN Configuration Check page (LUNs > LUN ConfigCheck) checks the configuration of LUNs, initiator groups, and FCP on the storage system and displays the results.
New Audit Log page
The new Audit Log page logs all administrative actions performed on a filer. You can see Audit Logs in the /etc/log/auditlog file.
Enhanced Quota Report
The Quota Report page (Volumes > Quotas > Report) has been enhanced to allow you to filter quota data by volume and quota type and to display warning and error indicators when the amount of disk space used approaches the 80% and 90% hard limit, respectively.
Volume wizard: specifying total or usable volume size and modifying the Snapshot reserve
The Volume wizard now allows you to indicate whether the value you specify in the Volume Size field is the total volume size, which includes space reserved for storing Snapshot copies, or only the space usable by the active file system, which does not include the Snapshot reserve. You can also modify the percentage of the volume reserved for storing Snapshot copies from its default of 20%.
Aggregate and volume wizards: allowing disks of different RPM
By default, Data ONTAP does not allow you to mix disks with different RPM speeds for aggregates and traditional volumes. However, the Aggregate and Volume wizards now include a checkbox you can select if you want to override this setting and allow the addition of mismatched disks selected in the Disks to Add field. If you have selected disks with different RPM speeds, you will not be allowed to add the disks unless you select the checkbox. This setting is not saved; you must select the checkbox each time you choose to override the default setting in order to add mismatched disks.
DataFabric Manager menu renamed to Operations Manager
The web-based user interface to DataFabric Manager has been renamed to Operations Manager. Accordingly, the menu used to enable and configure FilerView access to this interface has been renamed to Operations Manager.
See the FilerView help topics for these features for more information.
Support added for FlexClone volumes
FilerView now supports the creation and management of FlexClone volumes. When the FlexClone license is installed, the Volumes menu includes a FlexClone Volumes submenu with links to the FlexClone wizard, the Manage FlexClone volumes page, and the FlexClone Volumes Hierarchy page, which helps you track the FlexClone hierarchies on your storage system by displaying an indented view of child FlexClone volumes for a selected flexible volume or FlexClone or of all the FlexClone volumes on the system.
The Manage Volumes page now also includes a field that indicates whether a volume displayed on the page is a FlexClone volume.
New Host Name Resolution Policy wizard
The new Host Name Resolution Policy wizard (Network > Configure Host Name Resolution (DNS & NIS)) enables you to enable, disable, and configure DNS and NIS settings on the storage system. Settings you can use the wizard to configure include whether you want DNS entries to be updated dynamically after the update interval and whether you want to enable an NIS slave on the storage system.
New Volume Restore wizard
The Volume Restore wizard (Volumes > Restore) uses SnapRestore to revert an entire volume to its state when a specified snapshot was taken.
Attention: When a volume containing LUNs is restored, the LUNs must be taken offline or be unmapped prior to recovery. Using SnapRestore on a volume that contains LUNs without stopping all host access to those LUNs can cause data corruption and system errors.
New Date/Time wizard
The new Date/Time wizard helps you modify the system date and time manually or by using a time daemon to keep the system time synchronized with a time server. It is recommended that you use a time daemon, because problems can occur when the system clock is inaccurate. The time synchronizes the storage system date and time to an accuracy within one second of the date and time of the remote host.
Note: There is currently no Windows 95 or Windows NT counterpart for synchronization. You must have a UNIX workstation that supports remote synchronization on your storage system network.
Disk scrub added to Disk Report page
From the Disk Report (Storage > Disks > Report), you can now scrub disks to check RAID group parity on RAID groups at the RAID group level, plex level, or aggregate or traditional volume level. Parity checking compares the data disks in a RAID group to the parity disk in a RAID group. If during the parity check Data ONTAP determines that parity is incorrect, Data ONTAP corrects the parity disk contents.
New Modify Default Security wizard for iSCSI initiators
The Manage Initiator Security page (LUNs > iSCSI > Manage Initiator Security) has a new wizard that allows you to define default security settings for iSCSI initiators. Default security settings are used when an initiator attempts to access the system and no other security settings have been defined for the initiator.
Additional values displayed on the Volume Properties page
The Volume Properties page (Volumes > Manage > volume_name) displays additional volume option values, including whether SnapMirror is currently being used to update the mirror, whether the visible .snapshot directory is enabled, various SnapValidator for Oracle settings, and whether the system performs additional status checking at boot time to verify that the NVRAM is in a valid state.
Deleting empty qtrees
You can now delete empty qtrees using the Manage Qtrees page (Volumes > Qtrees >Manage).
Filtering items in the Manage Aggregates page
You can now filter the display in the Manage Aggregates page (Aggregates > Manage) to show only aggregates containing flexible volumes, traditional volumes, or aggregates under SnapLock restriction.
See the FilerView help topics for these features for more information.
