HP-UX 11i v3 Read Before Installing or Updating, February 2007 (Initial Release)

/dev/random or /dev/urandom Errors During Update
When updating your system to HP-UX 11i v3, you may
encounter the following error message in the
/var/opt/swm/swm.log file:
*Running "/var/adm/sw/pre_update/RNG-DKRN.100".
ERROR: The /dev/random or /dev/urandom device special files may
not be in use during update-ux. Use the fuser(1M) command to
identify these processes, then terminate them.
ERROR: The script "/var/adm/sw/pre_update/RNG-DKRN.100" returned
a value of "1" (ERROR)
*Running "/var/adm/sw/pre_update/RNG-DKRN.100" failed with 2
errors
What To Do
Run fuser /dev/random or fuser /dev/urandom to
retrieve a list of process IDs that are using the special
device files. Use the process ID along with the ps
command to determine what processes are using the
special device files.
If you find mxdtf, mxdomainmgr, or mxinventory as part
of these processes, then run /opt/mx/bin/mxstop to stop
all HP SIM activities before updating to HP-UX 11i v3.
