Tivoli Space Manager for UNIX Using the Hierarchical Storage Management Clients

dsmmigfs

Valid on AIX JFS file systems for HACMP environment only. You must have root user authority to use this command.

The dsmmigfs command allows an HSM-managed file system to be part of a resource group in an HACMP cluster. In the event of a system failure, you can obtain access to the data from another system.

Parameters

Export
Removes an HSM-managed file system from the current file system without recalling the file data. When you export space management from a file system, HSM removes the entry for your file system /etc/adsm/SpaceMan/config/dsmmigfstab and unmounts the fsm-mounted file system. Enter this command before the AIX volume group export (exportvg).
Note:
The export command does not reconcile the file system or delete the .SpaceMan directory.

Import
When you import a file system, HSM connects a takeover file system to your local system. Use this command after the AIX import volume group (importvg) occurs. Run the dsmreconcile command to update the status file for your file system after you enter dsmmigfs import.

-SErver=server name option
The server to contact for space managment services. Define the server in a stanza in your dsm.sys file. If you do not specify a server name, the default migration server that is defined in your dsm.opt file is used. To set the server to the default migration server, you also can specify the string "-" for the server option.
Note:
This option applies to the import parameter only.

filesystemspec
The file system name that performs the specified action. You can specify more than one file system name, and you can use wildcard characters within a file system name. If you specify more than one file system name, separate each name with one or more blank spaces.

Examples

Task Command
Export space management for the /home file system. dsmmigfs export /home
Import the space-managed file system, /home, for server, HSMServer. dsmmigfs import /home -server=HSMServer
