How to install GPFS 3.5 in RHEL6

Install GPFS 3.5 in RHEL6. The file system of the gpfs cluster has three hosts as an example. 1. Install gpfs software (run on three hosts). This installation is directly installed from the db2 purescale installation media, for other installation methods, see yum install/tmp/gpfs /*. rpmrpm-qa gpfs verification software has been correctly installed 2. compile the relevant software, after the rpm package is installed, cd/usr/lpp/mmfs/src & make Autoconfig & make World & make InstallImages [root @ linux1 src] # make rpm is installed and compiled the automatically generated RPM package yum install/root/rpmbuild/RPMS/x86_64/gpfs. gplbin-2.6.32-131.0.15.el6.x86_64-3.5.0-0.x86_64.rpm3, modifying the PATH (run on three hosts In the HOME directory of the three hosts.
