weird situation met at booting OS - /etc/services gone!

[stephen peng]

dear all,
I've got a problem. HP-UX 11.11, before, it failed when installing some patches and some libraries property were modify, like /usr/lib/dld.sl, and later I modified them to original(777 to 555), and then when i reboot the os, it could not get right. after I try to boot it to run level 3, I found /etc/services' size was 0, so i copy /usr/newconfig/etc/services to replace the old file and reboot, more problems came. I got following messages:
/sbin/rc1.d/S093vxvm-reconfig[47]: /etc/vx/lib/vxcommon: not found
/sbin/rc2.d/S620xfs[10]: env: not found
/sbin/rc2.d/S620xfs[10]: grep: not found
interpreter "/bin/sh" not found
file link resolves to "/usr/bin/sh"
/sbin/rc[14]: /sbin/rc2.d/S890ServCtlMgr: not found
interpreter "/bin/sh" not found
file link resolves to "/usr/bin/sh"
/sbin/rc[14]: /sbin/rc2.d/S996vradmind: not found
interpreter "/bin/sh" not found
file link resolves to "/usr/bin/sh"
/sbin/rc[14]: /sbin/rc2.d/S996vxrsyncd: not found
/sbin/rc[14]: /sbin/rc3.d/S99prngd.rc: not found
then I boot the single user, mount /usr, and replace the null /etc/services again, and init 3, it was good! I tried to reboot again, the same problem appear!
It seemed that I had to boot to single user mode then mount /usr, and replace the null /etc/service to make it well.
what could this situation be? I don't think it was a must step to mount /usr at single user mode. was system library messed up? please offer me some hints.
If you need more detail, just give your words.

thanks a lot

those "no found" messages appeared after bcheckrc and
/sbin/auto_parms: DHCP access is disabled (see /etc/auto_parms.log)

And I found no strange modification at /sbin/init.d

Probably, the recovery action done, didnt solve all problems.

Go through the /var/adm/sw/swagent.log, check what went wrong, when installing the patches, see if what sort of state the installed patches are now (#swlist -l fileset -a state) and work out a action plan from there..

Or just log a call with HP Support...

Greetz,
Chris

It may be time to get out your ignite backup.

one sad thing, no tape for this server, then, no ignite backup for it.

You can make ignite network backups.
