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 (Version 1 fileset) to a D40-version catalog (Version 2
fileset) to add support for symbolic links.
• Upgrade a Version 2 catalog fileset to a Version 3 catalog fileset to add support for OSS
ACLs.
NOTE: You can use this command to upgrade to a Version 3 catalog filesset on systems
running H06.08 or later H-series RVUs, or G06.29 or later G-series RVUs only. J-series
RVUs use Version 3 catalog filesets, so you do not need to upgrade them.
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 Version 3 fileset catalog to a Version 2 fileset catalog to remove support
for OSS ACLs.
CAUTION: When you downgrade a fileset catalog from Version 3 to an earlier version,
all optional ACL entries for files in the fileset are removed. The file owner and file other
permission bits are retained, and the class entry permission bits are used for the group
permission bits for the file. You can use this command to downgrade a Version 3 fileset
catalog on systems running J-series RVUs, H06.08 or later H-series RVUs, or G06.29 or
later G-series RVUs only.
• Downgrade a D40-version catalog (Version 2 fileset catalog) to a D30-version catalog
(Version 1 fileset catalog) to remove support for symbolic links.
CAUTION: When you downgrade a fileset’s catalog to a D30 version (Version 1), all
symbolic links in that fileset are removed. Attempts to access files in that fileset through
symbolic links from other filesets will fail. Version 1 filesets are not supported on G06.29
and later G-series RVUs, H06.08 and later H-series RVUs, or J-series RVUs.
If you attempt to downgrade to a fileset version that not supported on the RVU running on the
system, no downgrade occurs.
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
