Problems Configuring HP-UX 11i
Read these items before installing or updating to 11i.
HP recommends that you do not enable or use the CacheFS feature of
NFS (Network File System) under 11i until a patch is available. The
CacheFS file system is a general purpose file system caching mechanism
that improves NFS server performance and scalability by reducing
server and network load.
HP has discovered problems in the operation of CacheFS under HP-UX
11i:
• The umount command sporadically hangs when you try to un-mount
a cache directory.
• Client caching ceases after a server file is altered more than once and
the client attempts to re-read the server file.
To discover whether or not CacheFS is already in use on your system,
enter:
bdf -t cachefs
If the command returns anything other than a blank line, CacheFS is in
use. You should disable it: unmount the filesystems in question and
remount them without the cachefs option. Make sure the changes are
reflected in /etc/fstab.
Make sure all administrators know that they should not use a
combination of commands such as the following; and comment them out
of code and scripts:
cfsadmin -c -o options cache_directory
mount -F cachefs -o backfstype=nfs,cachedir= cache_directory \
server :/ mntdir / mntpnt [ local_mount_point ]
Contact your HP Support Representative if you need more information.
The A5838A PCI adapter does not support the boot, swap, and dump
commands under HP-UX 11i. The A5838A is a card with a PCI-to-PCI
bridge; it supports multiple devices.
To determine if an A5838A adapter is installed in your system, enter:
ioscan -kfClan | grep btlan3
