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

2. Do one of the following:
• If the fileset is the root fileset, stop all filesets by entering the following OSS Monitor SCF
command:
STOP FILESET $ZPMON.*
• If the fileset is not the root fileset, use the SCF STOP FILESET command.
For example, to stop (unmount) the fileset USER1 and send informational messages to the
file CMDLOG, enter the following SCF command:
STOP /OUT CMDLOG/ FILESET $ZPMON.USER1
If a user remains logged in with a current working directory in the stopped fileset, that user might
need to use the cd command again to return to the directory after the fileset is restarted; otherwise,
files in the restarted fileset might not be accessible to the user.
Reconfiguring a Fileset
You can reconfigure a fileset by:
• “Changing the Operating Parameters of a Fileset” (page 152)
• “Changing OSS File Caching for the Disks of a Fileset” (page 155)
• “Changing the Physical Makeup of a Fileset” (page 157)
Changing the Operating Parameters of a Fileset
You change a fileset configuration when you enter new values for:
• Automatic restart (DESIREDSTATE attribute)
• Fileset recovery utility processor choice (FSCKCPU attribute)
• Fileset recovery utility log file destination (REPORT attribute)
• Fileset auditing (AUDITENABLED attribute)
• Restricted access (RESTRICTEDACCESS attribute)
• Fileset input/output fault-tolerance (FTIOMODE and NORMALIOMODE attributes)
• Fileset catalog buffering (the BUFFERED attribute)
• Fileset storage-pool storage-pool file (POOL attribute)
• Maximum number of files and directories (MAXINODES attribute)
• User access restriction (the READONLY attribute)
• These Network File System (NFS) attributes:
Request timeout (NFSTIMEOUT attribute)◦
◦ Cache (pool) size (NFSPOOL attribute)
◦ NFS permissions map (NFSPERMMAP attribute), for J06.09 and later J-series RVUs and
H06.20 and later H-series RVUs only
NOTE: Changing the NFSPERMMAP attribute on an OSS fileset in which NFS clients
currently have open files can confuse some NFS client software because the mapped
NFS permissions seen by the NFS client system might suddenly change. For example,
buffered file library routines that are successfully writing, then are denied by an
NFSPERMMAP change, and then are allowed by an NFSPERMMAP change, might return
unexpected errors. Therefore, HP recommends that the OSS administrator stop the NFS
client software that is using an OSS fileset before changing the NFSPERMMAP attribute
of that fileset.
