That's good to know Jerry, thank you. 
shutdown was normal and successful, the POR of the box and the fact I had both 
checkpoints in the CF's (both CF's on the same CEC) cause me to loose spool 
data, well and the fact I didn't have the luxury of time to research my 
alternatives during that shutdown weekend. 
thanks again for the sanity check, Much appreciated !

We run with CKPT1 in the CF and CKPT2 on DASD for DR recovery. You should have 
no issues mixing. 

You certainly should not have lost your spool just because you shutdown - I'm 
assuming cleanly

Subject: EXTERNAL: JES2 Checkpoint question 

I've looked and looked at the Init and Tuning REF and Guide and I can't seem to 
find an answer to my question, I'm hoping someone can provide a sanity check 
for me. 
I have a 2 system JES2 MAS both running z/OS 2.1, both checkpoints are 
currently in a CF with mode=duplex and duplex=on. 
my issue is both CF's are in the same CEC so a POR of the box for maint last 
month I lost all my prod spool data and was forced to perform a JES2 cold 
start. I need to move CKPT1 to DASD and I want to leave CKPT2 in the CF, so my 
question is can I still run with mode=duplex and duplex=on in that 
configuration, or do I need to have both CKPT's on DASD. 
Any insight or recommendations would be very helpful, thank you all
