Issue:
The system was IPLED with the wrong LIBR init statement in CAS9 proc/stc.
Release 4.3 was inited and should have been 4.4
Can we start CAS9 as normal, with the new LIB 4.4 inits statement, along with all of the other statement that were done at the initial IPL?
If not what is the best/correct process to run just to do LIBR 4.4  
Resolution:
Need to first delete the Librarian 4.3 and then reinit with Librarian 4.4

Create a copy of the CAIRIM member and create one that contains only the Librarian statements:
PRODUCT(CA-LIB43) VERSION(LJ43) INIT(LJ43INIT) - 
PARM(DELETE,NAME=LAM) 

PRODUCT(CA-LIB44) VERSION(LJ44) INIT(LJ44INIT) - 
PARM(REINIT,NAME=LAM) 

Restart CAS9: 
s cas9

Restore the CAIRIM member to the full member and update the Librarian statement.
