    Mellanox OFED cluster install questions

      *Noob warning*

       

      Having trouble understanding the installer for this...

       

      Backstory: We have a cluster that is currently running OFED 1.5.4.1 <-- very old in /opt/ofed

       

      Goal: Have old IB 1.5.4.1 in place but also have new IB in place so users can use both.

       

      Testing:

      Downloaded mellanox package (MLNX_OFED_LINUX-3.1-1.0.3-rhel6.7-x86_64) on our test cluster.

      ./mlnxofedinstall

      Note that all other Mellanox, OEM, OFED, or Distribution IB packages will be removed.

      Do you want to continue?[y/N]:y

       

      Install completes and nothing appears touched in /opt/ofed

       

      Next test (newer installer):

      Downloaded mellanox package (MLNX_OFED_LINUX-3.2-1.0.1.1-rhel6.7-x86_64) on our test cluster.

      ./mlnxofedinstall

      Note: Everything under /opt/ofed was removed...

       

      Questions:

      What happened!? Why did it not delete the files in /opt/ofed on the older installer, but did with the new installer?

       

      Also, why can't I prefix the install? Previously, when building just OFED you could add a prefix to the conf file. Now, it says it doesn't support prefix? This means I now have 3 folders in /opt

       

      ibutils

      mellanox

      Knem-1.1.2.90.mlnx1

       

      Is there a way to add a prefix to this type of install that I am missing?

       

      Thanks, and any help is greatly appreciated.
