Moving and Removing OSS Catalog Files
•
To restore from a backup tape a catalog that has been destroyed due to a double
media failure:
1. Use the Guardian RESTORE utility VOL keyword to restore the catalog to a
subvolume whose name does not begin with ZX0.
2. Move the catalog onto the ZX0 subvolume with a TACL command of the
following form:
RUN $SYSTEM.ZOSS.CVT RENAME CURRENT IN nonZX0subvol &
TO CURRENT IN ZX0subvol
3. After you restore the catalog, run the integrity checker with the following SCF
command:
DIAGNOSE FILESET fileset, REPAIR ALL
•
When FSCK detects catalog corruption, it does not repair the catalog in place;
instead, it creates a new catalog and saves the old one. The old catalog is saved
under the Guardian file identifiers PXINnnnn, PXLInnnn, and PXLOnnnn (where
nnnn is an FSN).
To remove an old catalog retained by FSCK, enter:
RUN $SYSTEM.ZOSS.CVT PURGE SERIAL fsn
where fsn is the FSN of the old catalog.
