Hi Chris, Since you mention GRIDScaler, I assume that you are a DDN customer and that you have a support contract with them. If not, then feel free to take the advice that follows with a measure of salt although it mostly still applies ;-) With 4.1, there are now 'Editions' of GPFS, which break out various feature sets into a tiered arrangement, with each tier being licensed (and possibly priced) differently. Have a look here (Q 1.3) for the 4.1 licensing notes - http://www-01.ibm.com/support/knowledgecenter/SSFKCN/com.ibm.cluster.gpfs.doc/gpfs_faqs/gpfsclustersfaq.html
With GPFS 3.5, you are most likely running the equivalent of the 'Standard Edition' today. The crypto feature set comes with the 'Advanced Edition', which is licensed differently. Have a look at Chapter 15 of the Advanced Admin Guide for 4.1 as a primer ... http://www-01.ibm.com/support/knowledgecenter/SSFKCN_4.1.0.4/gpfs4104_content.html -frank On Thu, Apr 16, 2015 at 1:33 PM, Garrison, E Chris <[email protected]> wrote: > Hello, > > My site is working up to upgrading our paired GridScaler system from > GPFS 3.5 to 4.1.
