Tivoli Space Manager for UNIX Using the Hierarchical Storage Management Clients
Space management must be active on your file system to completely remove
it. Ensure that you have space on your file system to recall all
migrated files. Before you remove space management from your file
system, ensure that all activity on your file system has stopped and that the
file system is not being accessed.
On an AIX JFS workstation, if the file system is being accessed when you
remove space management, the FSM cannot unmount from the file system, and the
TSM backup-archive and space management functions will not work
correctly. If the FSM does not unmount when you remove space management
from your file system, enter the unmount command for the file
system to unmount it after all processes no longer access your file
system.
When you remove space management from your file system, the HSM client
performs the following:
- Runs reconciliation for your file system. If any orphaned stub
files are located, a notification is posted. Check the
orphan.stubs file in the .SpaceMan directory for a
list of orphaned stub files. To remove space management, first resolve
all orphaned stub files, and then try again. For more information, see Resolving Orphaned Stub Files.
- Determines how much space is required to recall all migrated files.
If there is not enough space, the HSM client notifies you. To remove
space management, make space available and try again.
- Recalls migrated files to the file system in the most efficient recall
order based on where they are stored.
- Notifies the server to delete all migrated files from storage.
- For AIX JFS file systems, unmounts the file system migrator (FSM) from the
file system.
- Removes the entry for the file system from the dsmmigfstab file that is
stored in the /etc/adsm/SpaceMan/config directory, and deletes the
.SpaceMan directory from your file system.
- Updates information for your native file system.
For AIX JFS file systems, if the /etc/filesystems
file contains a stanza for the file system, HSM sets the mount
attribute to true and removes the adsmfsm attribute.
For Solaris VxFS file systems, if the /etc/vfstab
file contains an entry for the file system, the HSM client updates only the
dsmmigfstab file.
To remove space management from one or more file systems, follow these
steps:
- Click Space Manager in the Hierarchical Storage Management
window.
- Highlight the file systems that you want to remove from space
management.
- Click Selected>Remove Space Management to
view the Question Dialog window. When you select more than one file
system, a Question Dialog window displays for each file system.
- Click OK to recall all migrated files and continue with the
remove process. The Remove Status window displays.
- Click Cancel in the Question Dialog window if you want to
prevent HSM from removing space management from your file system.
- Click Stop in the Remove Status window if you want to end the
process. However, any file that was recalled remains in a premigrated
state. Space management is not removed from your file system.
Your file system remains in an active state.
- Click Close to close the Remove Status window.
Use the dsmmigfs command to remove space management. For
example, to remove space management from the /home file system,
enter:
dsmmigfs remove /home
See dsmmigfs for more information about this command.
