Moving and Removing OSS Catalog Files
DIAGNOSE FILESET filesetname, UPGRADE
filesetname
specifies the fileset to have its catalog file upgraded so that it can support
current OSS features.
4. As soon as the upgrade operation is complete on the fileset catalog file, use the
SCF START FILESET Command for the fileset. Note that the root fileset must be
started before any other fileset can be started.
All mounted filesets can be stopped in one operation by using the wildcard character *
in place of a fileset name in the SCF STOP command. To run the SCF DIAGNOSE
FILESET Command on multiple filesets, use the CPU option to begin the process for
each fileset on a different processor.
Moving and Removing OSS Catalog Files
OSS catalog files cannot be moved or purged with standard OSS or Guardian file-
system commands; you must use the Guardian Catalog Volume Tool (CVT) utility.
CVT is useful in cases such as:
•
You can purge old catalog files once you have decided that an FSCK repair
operation was successful and the old files are no longer needed.
•
In the rare case of a double media failure, you can still perform a partial catalog
recovery by restoring the latest backup copy of the catalog file and running the
SCF DIAGNOSE FILESET command with the REPAIR ALL option.
The Guardian RESTORE utility cannot open files on OSS catalog subvolumes, but
you can restore the catalog to another subvolume and then use CVT to move the
restored catalog to the OSS catalog subvolume.
CVT also enables you to:
•
Move catalog files between subvolumes on the same disk volume
•
Move catalog files onto and off of ZX0 subvolumes
•
Save a current catalog in the same manner that FSCK does when it saves an
existing catalog and creates a new one
•
Make a saved catalog the current catalog for a fileset
•
Purge catalog files saved by FSCK
CVT is an unlicensed privileged program and, therefore, can be run only by the
super ID (which is 255,255 in the Guardian environment, 65535 in the OSS
environment). CVT is restartable; if it fails while moving or purging a catalog file, you
can restart it using the same command.
