Server and Cluster Administration Guide for Hitachi NAS Platform

Part Number
Navigate to Home > Server Settings > EVS Management, and click details to display the EVS Details page.

Field/Item Description
Name EVS identifier (same as Label in the previous page).
rename Applies the new label entered in the Name field.
EVS ID Unique identifier for the EVS within the cluster, generated by the server upon EVS creation.
Note: If moved to another server in a server farm, the EVS ID might change, but not if the move is within a cluster.
Status Service status:
  • Online: Up and capable of providing services.
  • Offline: Not running. While offline, EVS are inaccessible.
Type Type of service provided by the EVS: administration services or file services.
Enabled Yes (enabled), or No (disabled).
Preferred Cluster Node Indicates cluster node preference for the EVS (only displayed for file serving EVSs in a cluster). The EVS might, however, be hosted by a node other than its preferred node after having been migrated for several reasons, such as node failure, manual migration for load balancing, and so forth.
apply Applies a new preferred cluster node selected from the Preferred Cluster Node list.
EVS Security Displays the current EVS security context. Click change to select a different EVS security context, or to select the global configuration.

Selecting a different EVS security context changes how EVS name services, user mappings, group mappings, localgroups, name space (CNS), DNS servers, and NIS/LDAP configuration settings are managed.

  • If an EVS uses the Global configuration, any changes made to the global configuration settings will affect the EVS.
  • If an EVS uses an Individual security context, changes made to the global configuration settings will not affect the EVS. To change the settings of an EVS using an individual security context, you must go to the configuration settings for the EVS' individual security context, even if those settings are the same as the settings used by the global security context.
Note: You must disable the EVS before you can switch the EVS security context being used (between the global security context and an individual security context).
Default File System Security Mode Displays the default security model to be used by file systems in the EVS. If the EVS is disabled, this field does not contain a security model as the security configuration of a disabled EVS cannot be retrieved.
File Systems List of all file systems hosted by the EVS. For more information about a particular file system, click its name to display its File System Details page.
Note: Administrative EVSs (EVS Type set to Admin Services), the this area is not displayed
IP Addresses Displays a list of all IP addresses assigned to the EVS. Note that an EVS can have multiple IP addresses.
Port The cluster node interface to which the IP address for the EVS is assigned.
IP Address The IP address and subnet mask for the EVS.
enable/disable Controls the status of the EVS.
delete Removes the EVS. Do not click delete until you first disable the EVS.
Note: Deleting an EVS does not affect the file system owned by the EVS. After the EVS has been deleted, assign the file system to another EVS to make it available for use.
IP Addresses Opens the IP Addresses page.
EVS Migration Opens the EVS Migration page.
