Tivoli Header
Tivoli Space Manager for UNIX Using the Hierarchical Storage Management Clients
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.
