EMC NetWorker Release 8.1 SP1 Installation Guide 67
AIX Installation
To prevent the time out of NetWorker commands, change the default name resolution
lookup behavior to prevent IPv6 lookups. AIX uses three methods to configure the name
resolution mechanism. Ensure each method does not try to perform IPv6 lookups:
◆ NSORDER environment variable.
From the system prompt, type:
env
If the NSORDER variable is not NSORDER=local,bind4 , type:
export NSORDER=local,bind4
◆ /etc/irs.conf file.
Ensure the hosts entries are:
hosts local
hosts dns4
◆ /etc/netsvc.conf file.
Ensure the hosts entry is:
hosts=local, bind4
Changing the default directory locations
This section describes the installation location of the NetWorker software and the disk
space requirements.
The AIX installp utility installs the NetWorker software. This utility does not enable you to
change installation location of NetWorker binaries.
The NetWorker software installs the binaries in the /usr/bin directory. If there is
insufficient disk space to install the NetWorker software, the AIX installp utility allocates
more disk space, to successfully complete the software installation.
The /nsr directory contains the NetWorker configuration, logs, and database files. To
change this location create a symbolic link from the new directory to the /nsr directory.
For example:
1. Create another nsr directory on a disk with sufficient space:
mkdir /disk2/nsr
2. Link the new directory to the /nsr directory:
ln -s /disk2/nsr /nsr
Before you install the NetWorker software, ensure that:
◆ The PATH variable for the root and user accounts contains the /usr/bin directory.
◆ There is sufficient disk space to install the NetWorker software.
