CVT - T8621G09 - (01FEB01) OSS Catalog Volume Tool

CVT { RENAME <files1> [ TO ] <files2> }

{ PURGE SERIAL <serial#> [IN <subvol> ] }

where <files1> and <files2> are:

{ CURRENT } [ IN <subvol> ]

{SERIAL <serial#> [ IN <subvol> ] }

CVT Examples

Here are some examples of CVT commands:

• To purge the files PXIN0004, PXLI0004, and PXLO0004 on subvolume $VOL.ZX000003,

enter the following command at a TACL prompt:

RUN $SYSTEM.ZOSS.CVT PURGE SERIAL 4 IN $VOL.ZX000003

• To save the current catalog on $VOL.ZX000003 as PXIN0004, PXLI0004, and PXLO0004

on the same subvolume, enter the following command at a TACL prompt:

RUN $SYSTEM.ZOSS.CVT RENAME CURRENT IN $VOL.ZX000003 TO &

SERIAL 4 IN $VOL.ZX000003

This command is equivalent to the following command sequence:

VOLUME $VOL.ZX000003

RUN $SYSTEM.ZOSS.CVT RENAME CURRENT TO SERIAL 4

• To make the current catalog on $VOL.TEMP the current catalog on $VOL.ZX000003, enter

the following commands at a TACL prompt:

VOLUME $VOL.ZX000003

RUN $SYSTEM.ZOSS.CVT RENAME CURRENT IN TEMP TO CURRENT

• 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.
