Why would you want to do this? I presume you have the health-check recommended 4 backups (or more). If the current backup is 'N', the next backup would be taken to N+1. N will not be overwritten for 3 additional cycles. More than long enough to make a backup copy.
To answer your question about fixcds prior to startup, no. What I have done is add the FIXCDS command to the end of ARCCMD* This will be executed before a CDS backup can occur. You can also bring dfHSM up in emergency mode obtain the backup number and issue the FIXCDS command followed by SETSYS NOEMERGENCY.

I am refining our DR procedures. After I restore the DFHSM CDSs from the most recent back-up, I need to update so as to not overwrite that back-up with the next occurrence of CDS backup. The fine manual says to use FIXCDS S MHCR PATCH(X'B1' nnnnnnn) to set the next back-up number. FIXCDS requires an active DFHSM. Is there a supported way to make this update BEFORE starting DFHSM on the recovered system? I have thought of running DFHSM itself with a specifically tailored parm to come up, FIXCDS, and stop, but this seems overkill. I can also do it "manually" during the steps documented for first IPL of recovered system, but this is more prone to error or omission. S DFHSM is in my COMMNDxx parmlib member.
