Checking and Repairing Fileset Integrity
9. If the catalog disk volume for the fileset is on the removed disk volume, 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.
10. Use the Guardian CVT utility described under Managing and Repairing Fileset
Catalog Files on page 5-40 to purge the saved catalog files (with file identifiers of
the form PXINnnnn, PXLInnnn, and PXLOnnnn) from the old catalog disk volume.
You can now physically remove the disk volume.
Moving a Disk Volume to Another Fileset
To move a disk volume from one fileset to another:
1. Remove the disk volume from the storage-pool file for its current fileset, using the
procedure described under Removing a Disk Volume From a Storage-Pool File on
page 5-22.
2. Remove the disk volume from its current fileset, using the procedure described in
Removing a Disk Volume From a Fileset on page 5-23.
3. Add the disk volume to the storage-pool file of the appropriate fileset, using the
procedure described under Changing the Fileset Catalog on page 5-21.
Checking and Repairing Fileset Integrity
This subsection describes use of the SCF DIAGNOSE FILESET command, which runs
the Guardian FSCK utility. The FSCK utility checks and optionally repairs the integrity
of an OSS fileset. FSCK issues EMS events at the start of each diagnostic operation,
every 5 minutes during the operation, and at the end of the operation; see FSCK
Messages on page A-6.
The DIAGNOSE FILESET command corresponds to the fsck command of many
UNIX systems. Only super-group users (255,nnn) can use the DIAGNOSE FILESET
command.
When Do You Need to Check Fileset Integrity?
You diagnose a fileset to make sure that you can read and write files in it.
The Guardian FSCK utility looks at every regular file to verify that it has both a
directory entry and data. FSCK makes sure that the superblock, inodes, and catalog
files are consistent. You can choose to repair all inconsistencies or only the serious
ones.
