DIAGNOSE FILESET Command
If the REPAIR option is omitted, the default value is REPAIR NONE.
When the REPAIR option is specified, you cannot specify the STATUS,
UPGRADE, or DOWNGRADE option.
UPGRADE
reformats the catalog for the fileset from an earlier version to a current version. For
example, you can upgrade a D30-version catalog to a D40-version catalog to add
support for symbolic links.
If the UPGRADE option is omitted, no upgrade occurs.
When the UPGRADE option is specified, you cannot specify the STATUS,
REPAIR, or DOWNGRADE option.
DOWNGRADE
reformats the catalog for the fileset from a current version to an earlier version. For
example, you can downgrade a D40-version catalog to a D30-version catalog to
remove support for symbolic links.
If the DOWNGRADE option is omitted, no downgrade occurs.
When the DOWNGRADE option is specified, you cannot specify the STATUS,
REPAIR, or UPGRADE option.
Considerations
•
You might specify a new processor with the CPU parameter if the processor on
which FSCK normally runs has stopped. You might also specify a particular
processor for load balancing.
•
You cannot use the DIAGNOSE FILESET command on a fileset that is in the
STARTED state (mounted).
•
When the DIAGNOSE FILESET command is used, the fileset is placed in the
DIAGNOSING state until the integrity check is complete. Then the fileset is placed
in the STOPPED state and can be remounted with the SCF START FILESET
command unless serious inconsistencies remain unrepaired.
NONE
Do not repair any inconsistencies. This is the default specification.
OPEN
Same as SERIOUS, but also assumes that there might be open
files in this fileset. This option indicates that inodes cannot be
reused until the next unmount or remount.
SERIOUS
Repair only serious inconsistencies. This option can speed up the
execution of a fileset check.
Caution. When you downgrade a fileset’s catalog to a D30 version, all symbolic links in that
fileset are removed. Attempts to access files in that fileset through symbolic links from other
filesets will fail.
