Changing OSS File Caching for the Disks of a
Fileset
If you disable OSS file caching, HP strongly recommends that you disable OSS file
caching on all the disk volumes in a fileset. To disable OSS file caching for a specific
disk volume, you must disable all filesets mounted on the affected fileset:
1. At a TACL prompt, enter:
SCF
2. At the SCF prompt, enter the following SCF command to stop each fileset involved:
STOP FILESET $ZPMON.filesetname
Enter this command beginning with the last fileset mounted on the affected fileset.
Stop the filesets in the reverse order in which they were last started. Stop the
affected fileset last. If the root fileset is the affected fileset, you can enter:
STOP FILESET $ZPMON.*
This command will stop all filesets in the correct order.
3. At an SCF prompt, enter the following set of commands once for each disk volume
in the fileset:
ALTER DISK diskname, OSSCACHING OFFdiskname
4. Restart the affected portion of the OSS file system by entering the following SCF
command one or more times:
START FILESET $ZPMON.filesetname
filesetname
is the name of each fileset that you previously stopped, specified in the order in
which mount points occur.
Similarly, to enable OSS file caching for a specific disk volume:
1. At a TACL prompt, enter:
SCF
2. At the SCF prompt, enter the following SCF command to stop each fileset involved:
STOP FILESET $ZPMON.filesetname
Enter this command beginning with the last fileset mounted on the affected fileset.
Stop the filesets in the reverse order in which they were last started. Stop the
affected fileset last. If the root fileset is the affected fileset, you can enter:
STOP FILESET $ZPMON.*
This command will stop all filesets in the correct order. This command begins with
the last fileset mounted and stops the filesets in the reverse order in which they
were last started.
