Tivoli Space Manager for UNIX Using the Hierarchical Storage Management Clients
A nested file system is a file system mount point that is contained within
another file system. For example:
/test
/test/migfs1
The /test file system is a parent file system and
/test/migfs1 is a nested file system within
/test. They are both mount points.
To add space management to a parent file system and any nested file
systems, follow these steps:
- Unmount the nested file systems.
- Add space management to the parent file system.
- Remount the nested file systems.
- Add space management to each nested file system. See Adding Space Management to Your File Systems for instructions to add space management to your local file
system.
To add space management to a parent file system but not to its
nested file system, perform steps one through three above.
For AIX JFS file systems only
For an AIX JFS-nested file system that mounts automatically when you
restart your system, follow these steps to mount the parent file system before
you mount the nested file system:
- Enter smit jfs.
- Select Change/Show Characteristics of a Journaled File
System.
- Select the nested file system.
- Set Mount AUTOMATICALLY at system restart? to
no.
- Select Do.
- Edit the /etc/rc.adsmhsm file that is shipped with the
HSM client and add the following statement in the nested file system section
at the end of the file:
mount /test/migfs1
Where /test/migfs1 is the name of the nested file
system.
- Note:
- With the exception of the Solaris HSM, the NFS is the only network file
system interface to export a file system that HSM supports.
To add space management to a file system that the NFS server exports,
follow these steps:
- Instruct all NFS clients to unmount the exported file system.
- To view which clients mounted the exported file system, enter:
/usr/sbin/showmount -a
- Add space management to your file system using the dsmmigfs
add command.
- To export the NFS file system again, enter:
/usr/etc/exportfs -a
- Instruct all NFS clients to mount the exported NFS file system
again.
