Installing and Configuring Enhanced DFS 3.0 Migrating root.dfs from UFS to Episode NOTE: CAUTION: NOTE: Migrating root.dfs from UFS to Episode After installing and configuring Enhanced DFS, if you want to migrate your root.dfs from a UFS aggregate to an Episode fileset, use the following procedure. This is a complete, but condensed procedure. For details about the files and commands used in this procedure, consult the OSF DCE DFS Reference Guide, Revision 1.2.2. An HTML version of this document is provided in the Enhanced DFS fileset EFS-DOCS, and installed in the directory /opt/dce/efs_docs. 1 Use the HP-UX Logical Volume Manager (LVM) to create the logical volume on which you want to store the Episode file system. Be sure to select "None" for the file system "Usage:" field for this logical volume. Alternatively, you can use the entire physical disk for the Episode file system, in which case no special steps are needed. 2 Add a line to the /var/opt/dce/dfs/dfstab file for the new Episode aggregate. For example: logical volume aggname /dev/vg00/lvol8 epi1 aggtype lfs aggid 2 3 Use the newaggr command to initialize an available disk partition (logical volume) as an Episode aggregate. Example: newaggr epi1 8192 1024 -overwrite Executing the newaggr command will destroy all existing data on the specified logical volume. For this release of Enhanced DFS, HP recommends specifying a block size of 8192 and a fragment size of 1024. 4 Use the dfsexport command to export the Episode aggregate so it is available for use in Enhanced DFS. Example: dfsexport -aggregate epi1 31

Installing and Configuring Enhanced DFS 3.0
Migrating root.dfs from UFS to Episode
Migrating root.dfs from UFS to Episode
After installing and configuring Enhanced DFS, if you want to migrate your
root.dfs
from a UFS aggregate to an Episode fileset, use the following
procedure.
NOTE:
This is a complete, but condensed procedure. For details about the files and
commands used in this procedure, consult the
OSF DCE DFS Reference Guide,
Revision 1.2.2
. An HTML version of this document is provided in the Enhanced DFS
fileset EFS-DOCS, and installed in the directory
/opt/dce/efs_docs
.
1
Use the HP-UX Logical Volume Manager (LVM) to create the logical volume on
which you want to store the Episode file system. Be sure to select "None" for the
file system "Usage:" field for this logical volume. Alternatively, you can use the
entire physical disk for the Episode file system, in which case no special steps are
needed.
2
Add a line to the
/var/opt/dce/dfs/dfstab
file for the new Episode aggregate. For
example:
3
Use the
newaggr
command to initialize an available disk partition (logical
volume) as an Episode aggregate.
Example:
newaggr epi1 8192 1024 -overwrite
CAUTION:
Executing the
newaggr
command will destroy all existing data on the specified
logical volume.
NOTE:
For this release of Enhanced DFS, HP recommends specifying a block size of 8192
and a fragment size of 1024.
4
Use the
dfsexport
command to export the Episode aggregate so it is available for
use in Enhanced DFS.
Example:
dfsexport -aggregate epi1
logical volume
aggname
aggtype
aggid
/dev/vg00/lvol8
epi1
