Preparing the environment on Linux nodes
Before proceeding with installation, prepare your environment by following the suggestions in the following sections.
Add the GPFS bin directory to your shell PATH
Ensure that the PATH environment variable for the root user on each node includes /usr/lpp/mmfs/bin. (This is not required for the operation of IBM Spectrum Scale, but it can simplify administration.)
Other suggestions for cluster administration
# uname -opr
3.10.0-693.el7.x86_64 x86_64 GNU/Linux
Once you have dsh set up, you can use it to install IBM Spectrum Scale on a large cluster. For details about setting up dsh or a similar utility, review the documentation for the utility.
Verify that prerequisite software is installed
Before installing IBM Spectrum Scale, it is necessary to verify that you have the correct levels of the prerequisite software installed on each node in the cluster. If the correct level of prerequisite software is not installed, see the appropriate installation manual before proceeding with your IBM Spectrum Scale installation.
Installing IBM Spectrum Scale without ensuring that the prerequisites listed in Hardware requirements, Software requirements, and Installation prerequisites are satisfied can lead to undesired results.
For the most up-to-date list of prerequisite software, see the IBM Spectrum Scale FAQ in IBM® Documentation.
