I'm installing SAS in a new environment, and this requests as a requirement to have the Platform LSF 10.1. My question is if I can have two versions of LSF on the same server. Is there the possibility that it results with errors?
Two versions of LSF will result in two resource managers thinking they have complete control over the machine's resources which will not be the case. Bot could think that a machine is good to launch a job on which will cause two jobs to go to the same machine. Not good workload management.
If your concern is putting a newer version of SAS on a machine without upgrading LSF, that is not a problem. SAS 9.4Mx comes with support for older versions of LSF, albeit possibly with reduced functionality. For example, 9.4M6 will support LSF 220.127.116.11 but ships with LSF 10.1.0.6
