Open System Services Management and Operations Guide (G06.30+, H06.08+, J06.03+)

1. Notify all users that the OSS file system is shutting down. Follow the procedure described

under “Sending Warnings to Users” (page 49).

2. Use the OSS shell ps command to identify all running OSS processes and then stop those

processes with the OSS shell kill command.

3. Use the SCF INFO FILESET * command to locate the mount point of each fileset if you do not

maintain a diagram of mount points.

4. Use the SCF STOP FILESET * command. You must stop filesets in a specific order; a fileset

cannot be stopped until every fileset mounted on it is stopped. The * specification stops all

filesets in the correct order. The last fileset to stop is the root fileset.

5. Use the SCF DIAGNOSE FILESET command with the REPAIR ALL option on all filesets.

6. Use the SCF START FILESET command on all filesets.

7. Start an OSS shell with the TACL OSH command.

8. Back up all OSS filesets. Use the procedure under “Backing Up User Files” (page 186) for all

files accessible from your root directory (/). Remember to avoid including files in /dev, /G,

and /E.

9. Use the OSS shell exit command to stop your OSS shell.

10. Use the SCF STOP FILESET * command to unmount all filesets.

11. Use the SCF DELETE FILESET command to delete each fileset. This action deletes all files in the

fileset, the catalog files for the fileset, and the fileset record in the configuration database.

12. Remove all previously saved catalogs by entering the following TACL command:

RUN $tsvvol.ZOSS.CVT PURGE SERIAL mmmm IN $old_vol.ZX0nnnnn

$tsvvol

specifies the disk volume of the installation target subvolume (TSV) containing the CVT utility.

See “Managing and Repairing Fileset Catalog Files” (page 170) for more information on the

CVT utility.

mmmm

specifies the FSCK serial number of a previous FSCK diagnose or repair operation. See

“Generated Catalog Files” (page 165) for more information on FSCK serial numbers.

$old_vol

specifies the disk volume on which you previously saved catalog volume files; such files have

names of the form:

PXffmmmm

specifies one of the following:

DescriptionValue

An old inode file for the catalogIN

An old link file for the catalogLI

An old FSCK log file for the catalogLO

mmmm

is the FSCK serial number.

nnnnn

specifies the device identifier for an OSS fileset.

When this procedure is completed, no one can use an OSS file until you reconfigure all filesets

and restore or reinstall OSS files. See the Open System Services Installation Guide for information

on installing the complete OSS product set.
