Installing ITO Agents on the Managed Nodes
General Installation Tips for Managed Nodes
If the file system which hosts the
/usr/lpp
file tree is too small to
install ITO Agents, create a symbolic link before installing ITO. For
example: if
/bigdisk
is a local file system with enough free space:
mkdir -p /bigdisk/OV
ln -s /bigdisk/OV /usr/lpp/OV
In a cluster environment, you must check that
/bigdisk
is also
accessible from all cluster clients, and that it is mounted from all
client nodes. For example, the local file system
/bigdisk
on the
cluster client must be mounted to the exported file system
/bigdisk
on the cluster server.
❏
In ITO version A.02.00 and later, agent software is installed under
the
/usr/lpp/OV
path name instead of under
/export/lpp/OV/rs6000/aix
as it was in earlier versions. Since
/usr
(or
/usr/lpp
) and
/export
normally belong to different file
systems, this means that enough disk space must exist on
/usr
(or
/usr/lpp
) file system before an upgrade to A.02.10 can be
successfully installed. This differs from other upgrades where
software is installed in the same directories as the previous version.
Disk space occupied by previous versions of ITO agents under
/export/lpp/OV/rs6000/aix
will be freed.
❏
AIX diskless nodes may initially be created so that root password is
not required. It is possible to remote login on these systems but
command execution with remsh will not be possible because .rhosts is
initially not present on the diskless client. FTP to this type of node
will also not be possible because the root password is empty. It is,
therefore, not possible to install ITO automatically on a diskless node
before either the root password is assigned or the .
rhosts
file is set
up properly. Note that initially the /etc/hosts file on the diskless node
also does not include the ITO management server.
Manual AIX Agent Installation
In some situations, it may be desirable to install the AIX agent software
without using the management server. This manual installation makes
it possible to prepare the workstation, so that it is ready to become an
ITO managed node when it is later connected to the network. This may
be useful if many workstations are prepared in some central location, or
if one wants to avoid the root connection over the network that is
necessary for a standard agent installation.
