  • Page 27 The fs Commands [<volume_name>] Specifies an unused metavolume for the checkpoint. A volume can be specified for only the first checkpoint of a PFS since all of the subsequent checkpoints share the same SavVol. Note: The minimum size required for a SavVol is 64 MB. The volume size is 10 gigabytes unless the PFS is less than 10 gigabytes, then the volume is the same size as the file system.

    The interface or IP address for the source and destination file system can be specified. The <cel_name> specified after the <dstfs> specifies the remote Celerra Network Server where the copy is to take place. If a <cel_name> is not specified, the copy is local.
  • Page 35 The -Force flag should only be used when explicitly directed in the Using Celerra Replicator, or on the instruction of EMC Customer Support. The -Force flag is mainly used within the procedure to transport an initial copy of a file system via tape or disk for Celerra Replicator.

  • Page 41: Fs_Dhsm

    [-localPort <port>] [-user <username>] [-password <password>] [-timeout <seconds>]} DESCRIPTION fs_dhsm modifies the properties on file systems enabled for Celerra FileMover. fs_dhsm creates, deletes, and modifies NFS, CIFS, and HTTP connections to remote hosts, lists Celerra FileMover file systems, and provides information on the connections.
  • Page 42 The fs Commands -info [<fs_name>|id=<fs_id>] Displays information for the specified Celerra FileMover file systems. -modify {<fs_name>|id=<fs_id>} Sets Celerra FileMover parameters for the specified file system. Note: When specifying the -modify option on a disabled file system, the state is automatically changed to enabled. To maintain the disabled state, specify -state disabled.
  • Page 43 -connection [<fs_name> | id=<fs_id>] -info [<cid>] Displays details on all Celerra FileMover connections or details on all connections for the specified file system. If the <cid> is specified, only information for that connection is displayed.
  • Page 44 The fs Commands Note: Although an IP address can be specified for an <nfs_server>, EMC strongly suggests using the hostname of the server, which allows you to take advantage of DNS failover capability. [-read_policy_override {full|passthrough|partial|none}] Specifies the migration method for data recall in response to client read requests.
  • Page 45 The fs Commands [-mntVer {1|2|3}] Specifies the mount version for the NFS connection. If the -type is nfsv3, then the -mntVer must be 3. If the -type is nfsv2, then 1 or 2 can be specified. The default for nfsv2 is 2. [-localPort <port>] Overrides the default port that the Data Mover uses during connection to be compatible with firewalls.
  • Page 46 Note: Although an IP address can be specified for a <host>, EMC strongly suggests using the hostname of the server, which allows the DNS failover capability.
  • Page 47 Use the -password option when digest authentication is required by the secondary storage HTTP server. [-timeout <seconds> Specifies the timeout value in seconds. By default, the Celerra HTTP client waits 30 seconds for a reply from the HTTP server and then retries the operation once.
  • Page 48 Celerra Network Server before the connection is removed. If no is specified and stub files exist, an I/O error appears when the file is read because the connection no longer exists.
  • Page 49 CONNECTIONS Specifies the name or IP address of the secondary NFS server. Note: Although an IP address can be specified for the <nfs_server>, EMC strongly suggests using the hostname of the server, which allows use of the DNS failover capability.
  • Page 50 [-password <password>] Allows the user to specify the admin password. The password is not recorded in the command log. If the -password option is given but no password is specified, the user is prompted interactively. Celerra Network Server Command Reference Manual...

  • Page 173 The nas Commands CAUTION The enterprise version of file-level retention is intended for self-regulated archiving. The administrator is considered a trusted user and the file-level retention capability does not protect the archived data from the administrator’s actions. If the administrator attempts to delete the file system, the file system issues a warning message and prompts the administrator to confirm the operation.
