Eric,

According to the search facility at the following page:
        http://techsupport.services.ibm.com/rs6k/fixdb.html
there does not appear to be any updates to "devices.fcp.tape.*".  We have
ML_07 applied to our systems, and they show devices.fcp.tape.rte at 4.3.3.0.

June 29th is the correct GA date for 4.2.  You should receive a letter from
Tivoli instructing you to contact upgrades AT tivoli DOT com to have it shipped 
to
you.

HTH,

Ted
