Hi All,

I was recently trying to determine the latest RHEL release that will work 
with GSS 2.0.7 (the latest IBM version of GSS code for x86_64). This code 
uses Scale 4.1.0.8.

A specific X.Y GSS code build, from my experience, is intended to use a 
specific RHEL version. For GSS 2.0, that's RHEL 6.5 (unless I am 
mistaken), which no longer has EUS support from RedHat (only 6.7 still 
does).

GSS 2.0 release notes/install docs say that "RHEL 6.5 or later" can be 
used, which is a surprising statement given GSS/ESS code's sensitivity to 
OS levels (any ESS I have ever seen has never been supported on more than 
one version of RHEL).

According to the Scale FAQ (
https://www.ibm.com/support/knowledgecenter/STXKQY/gpfsclustersfaq.html#linux
), A 2.2, Table 27, Scale 4.1.0.x is supported on RHEL 6.2 and above 
(implying RHEL 6.5 and 6.7). But Table 30 indicates that the latest RHEL6 
supported by Scale 4.1.0 is 6.6: for RHEL 6.7 kernel, however, indicates 
"From V4.1.1.2 in the 4.1.1 release" ... which contradicts Table 27!

Anyone know the truth of the matter? Should I stick to RHEL 6.5 to install 
GSS 2.0.7, or has it been demonstrated that RHEL 6.7 works (and is 
supported)? (and no, Lenovo-sourced code (GSS >= 2.5) is not an option 
here).

Many Thanks,
  Keith_______________________________________________
