Tivoli Space Manager for UNIX Using the Hierarchical Storage Management Clients


Mounting Your File Systems First

Note:
For AIX GPFS and Solaris VxFS file systems, an additional mount is not necessary.

Before you can migrate files to TSM storage, first mount your file systems either automatically or manually, and then add space management.

For AIX JFS file systems: Mount your file systems twice. Enter these commands to mount them:

   mount /fs
   mount -v fsm /fs

The first mount is for the physical AIX JFS file system. The second mount (with type fsm) is for the space management file system.

Mount the file system migrator (FSM) over the AIX JFS file system before you add space management services. The file system migrator is a kernel extension that intercepts all file system operations and provides any space management support that you require. If you do not mount the FSM, anyone with permission to access migrated files can access and modify your stub files. If a stub file is modified, the HSM client cannot access the migrated file.

After you add space management to an AIX JFS file system, do not unmount the FSM and directly access the native file system. If you unmount the FSM from a file system, enter the following command to remount it:

   mount -v fsm /fs

The /etc/filesystems file contains a stanza for each file system to which you add space management. The HSM client updates these stanzas so that the file system and the FSM both mount automatically whenever you restart your system.
