Changing the Physical Makeup of a Fileset
Changing the Fileset Catalog
To assign a new fileset catalog to a fileset:
1. Stop the fileset with the SCF STOP FILESET command, as described in Stopping
(Unmounting) a Fileset on page 5-13.
2. Use the SCF INFO FILESET Command with the DETAIL option to determine
whether the fileset uses the BUFFERED CREATE option.
If the fileset uses the BUFFERED CREATE option but not the READONLY TRUE
option, the creation pool for the fileset will be the new catalog disk volume of the
fileset; existing OSS files will not be moved to the new volume, but new OSS files
will be created on the new disk volume. Make sure that the new catalog disk
volume has adequate space for the fileset.
3. Use the SCF ALTER FILESET Command to enter a new name for the catalog disk
volume of the fileset.
This change causes current catalog files to be moved to the specified new disk
volume; previously saved catalog files (with file identifiers of the form PXINnnnn,
PXLInnnn, and PXLOnnnn) are not moved. The subvolume name of the catalog
files is not changed.
4. Use the CVT command described in Managing and Repairing Fileset Catalog Files
on page 5-38 to purge the saved catalog files (with file identifiers of the form
PXINnnnn PXLInnnn, and PXLOnnnn) from the old catalog disk volume.
5. Use the SCF START FILESET Command to restart the fileset.
To modify the limits in an existing fileset catalog, see Controlling the Maximum Number
of Files on page 6-29.
Adding a Disk Volume to a Fileset
To add a disk volume to a fileset (perhaps to make more storage space available):
1. Use a Guardian text editor to insert the disk volume name in the storage-pool file.
To avoid problems in managing fileset space, do not put the same volume in more
than one storage pool.
2. Do one of the following:
•
Use the SCF CONTROL FILESET Command with the SYNC option to make
the change take effect immediately.
•
Stop the fileset with the SCF STOP FILESET command, as described under
Stopping (Unmounting) a Fileset on page 5-13, then restart the fileset using the
SCF START FILESET Command.
The change takes effect when the fileset is restarted.
