I noticed after performing a SETLOAD 00,IEASYM that some of our system symbols were no longer in the list. The missing symbols are HRDWNAME, LPARNAME, OSLEVEL, SMFID, and VMUSER. Someone noted that these are the CA System Symbol Service symbols. Is there a way to refresh those outside of an IPL? We haven't noticed any impact. Is it safe to continue as is?
Common services for z/OS r14.1 in a z/OS 2.2  and above environment
If IBM utility IEASYMU2 is run, and a subsequent SETLOAD xxx,IEASYM  command is executed, the CAMASTER defined symbols will be removed. 
Apply RO97125 and any needed prerequisites   RO97125 requires a SETPROG LPA,ADD,MODNAME=CASRVSYM,DSNAME=LNKLST,FIXED,PAGEPROTALL command after the maintenance is applied so an IPL is not necessary.  LPA will be dynamically updated and remain in place until the next subsequent IPL when the updated CASRVSYM will become permanent. 
Additional Information:
RO97125 will resolve this problem.  Apply any prerequisites as necessary
