  SDA link mismatch warning? (SDALINKMISM) 
 The Question is:
 
Mr. Wizard,
 
After applying the patch "DEC AXPVMS VMS721_SYS V10.0" to a 7.2-1 system the
 ANALYZE/SYSTEM command produces a link mismatch warning message.  Has there
 been a subsequent patch to correct this problem?  Or might there be a way to
 uninstall the patch?
 
And yes, I am positive that this patch was the source of this error.  The
 sequence was 1) test SDA = no problem, 2) apply patch, 3) reboot, 4) test SDA
 = problem.
