to use the SL6 WNs you can:

login to a SL6 UI t3ui[12,15,16,17,18,19] and submit your jobs from that SL6 UI ; this is the simplest way, when a job is launched from a SL6 UI the batch system automatically requests a SL6 WN ( -l os=sl6 ).
from a SL5 UI t3ui0[2-9], by explicitely adding -l os=sl6 to the qsub command invocation ; conversely when a job is launched from a SL5 UI the batch system automatically requests a SL5 WN ( -l os=sl5 ).

Be aware that the CMSSW and the ROOT releases available in the SL6 WNs are different from the releases installed in SL5 WNs environment ; if you need a missing release please contact us by e-mail to cms-tier3 AT lists.psi.ch with cms-tier3-users AT lists.psi.ch in Cc to get it installed.
