HP-UX File systems

by default installs a single filesystem for /usr, /var and /tmp. The /tmp directory should be cleaned on a daily basis by some scavenger local admin shell script. Edit /usr/spool/cron/crontabs/root to contain

0 3 * * * /opt/bin/scavenger -t+1 /tmp/ >/dev/null

which will cleanup at 3 AM.

HP-UX 10.20/11.x

by default installs filesystems on different logical volumes

/       /dev/vg00/lvol3 
/stand  /dev/vg00/lvol1
/var    /dev/vg00/lvol8 
/usr    /dev/vg00/lvol7 
/tmp    /dev/vg00/lvol4 
/opt    /dev/vg00/lvol6 
/home   /dev/vg00/lvol5

The /tmp filesystem should be cleaned on a daily basis, use

crontab -e                     # or: vi /usr/spool/cron/crontabs/root
0 3 * * * /opt/bin/scavenger -t+1 /tmp/ >/dev/null

to specify cleanup at 3 AM by some scavenger local admin shell script.

Remote filesystems

are defined to share user, data and scratch files as well as applications. They are mounted via the autofs (HP-UX 10.x/11.x) or the older automount (HP-UX 9.x) mechanism.
Configuration files are:

/etc/auto.u:

/u    -rw,vers=3 rs6kf:/userfs/HPUX/68K/ # for 300/400 series
/u    -rw,vers=3 rs6kf:/userfs/HPUX/PA/  # for 700/800 series

/etc/auto.d:

bio   -rw,vers=3,proto=tcp rs6kf:/datafs/bio

/etc/auto.s:

bio   -rw,vers=3,proto=tcp rs6kf:/scratch/bio

/etc/auto.nfs:

texlive -ro                  rs6kf:/applfs/applb01/texlive
local   -ro                  rs6kf:/applfs/applb01/HPUX/68K # for 300/400 series
install -rw,vers=3,proto=tcp rs6kf:/applfs/applb01/HPUX/68K # write access to allow installation
local   -ro                  rs6kf:/applfs/applb01/HPUX/PA  # for 700/800 series
install -rw,vers=3,proto=tcp rs6kf:/applfs/applb01/HPUX/PA  # write access to allow installation

/etc/auto.master (HP-UX 9.x) or /etc/auto_master (HP-UX 10.x/11.x):
```
/-   /etc/auto.u          # direct map to allow new users in /u
/s   /etc/auto.s
/d   /etc/auto.d
/nfs /etc/auto.nfs
```
Note that the various mount points are created automatically.
Note further that apparently the vers= parameter is not supported for HP-UX < 11.
The automount daemon is activated at boot time on
- HP-UX 9.x
  in /etc/netnfsrc2 with the line(s)
```
/usr/etc/automount -f /etc/auto.master
```
  and in /etc/netnfsrc with
```
NFS_CLIENT=1
```
  Note that automount should never be send the SIGKILL signal, refreshes could be triggered via kill -s SIGHUP
  To enable NFS services:
```
NFS_SERVER=1
```
- HP-UX 10.x/11.x
  as
```
/usr/lib/netsvc/fs/automount/automount -f /etc/auto_master
```
  If necessary, it may be started manually
```
/usr/sbin/automount -f /etc/auto_master
```
  Verify in /etc/rc.config.d/nfsconf that the appropriate services (NFS client, automount) are enabled.
necessary links:
```
ln -sf /u /users
```
