Multiple configuration options are set when a file system is created. After the file system is created, you can configure additional settings such as enabling thin provisioning or setting usage thresholds. You can also modify existing settings such as the file system name or the default snapshot retention period.
- Navigate to Provisioning > Capacity > File Systems.
- Locate the file system that you want to configure, and then click View.
- In the file system name pane, click the edit icon.
- Configure or modify the following information, and then click Save.Tip: The information that you can modify depends on the managed server associated with the file system and the file system status.
- Name: Change the file system name.
- Deduplication: Enable or disable deduplication for the file system. This setting defaults to the setting selected when the file system was created.
- Thin Provisioning: Enable or disable thin provisioning for the file system. This setting is enabled by default.
- Security Mode: Select a security mode. By default, the file system inherits the security mode from the parent file system. For information about security modes, see Security modes.
- Inherited (Unix - supports Windows)
- Mixed (Windows and Unix)
- Unix (supports Windows)
- Object Replication Target: Enable or disable the file system as an object replication target.
This setting defaults to the setting selected when the file system was created.
- Syslock: Enable or disable syslocked mode for the file system. When syslocked mode is enabled for a file system, NDMP has full access to the file system and can write to it during a backup or replication, but the file system remains in read‐only mode to clients using the file service protocols (NFS, FTP, and iSCSI).
This setting is disabled by default.
- Transfer Access Points During Object Replication: Enable or disable the transfer of shares and exports (access points) during an object replication. If enabled, the file system can transfer access points during an object replication. If disabled, the file system cannot transfer access points.
This setting is disabled by default.
- Transfer XVLs as Links During Object Replication: Enable or disable the transfer of migrated files as links during an object replication rather than transferring the file contents.
This setting is disabled by default.
- Default Snapshot Retention: Enable or disable the default snapshot retention and set the retention interval period.
This setting defaults to the setting selected when the file system was created.
CAUTION:You cannot disable this option or decrease the retention interval after the option is enabled without the assistance of Hitachi Vantara Support. - Usage Thresholds: Set warning and severe usage thresholds for the file system. Usage thresholds are expressed as a percentage of the space that has been allocated to the file system. When a threshold is reached, an event is logged and, depending on quota settings, an email might be sent.
Set the Warning threshold to a high, but not critical, level of usage.
Set the Severe threshold to a critical level of usage. This threshold represents a situation in which an out‐of‐space condition might be imminent.
You can define both warning and severe thresholds for any of the following:
- Live file system: The percentage threshold for space used by data.
- Snapshots: The percentage threshold for file system snapshots.
- Entire file system: The percentage threshold for the total of the live file system data and snapshots.
To ensure that the live file system does not expand beyond the severe threshold, select Do not allow the live file system to expand above its Severe limit.
