At my last job this error was caused because /var was not mounted at the
boot time when the 
system wants to write to /var/adm/utmp.  Without /var mounted at boot time,
the /var/adm path 
does not exist.  What we did to avoid this message was to unmount /var and
create the
path /var/adm.  This creates the path from /.
 
What it does is make the path /var/adm available at boot time without having
/var mounted.
/var/adm/utmp and utmpx can then be created/written to at boot time.  When
the system 
comes up /var will be mounted normally and the system will use the mounted
/var/adm/utmp.

Hi Admins,
 
It seems that a power outage happenend and have corrupted the files
/var/adm/utmpx and utmp. 
When the system came back after power came back we get the msgs:

INIT: Cannot create /var/adm/utmp or /var/adm/utmpx

INIT: failed write of utmpx entry:"   "

INIT: failed write of utmpx entry:"   "
 
INIT: Single User Mode
 
...
 
We couldn't enter single user mode.
So we booted from cdrom, renamed the files utmp and utmpx to utmp and utmpx.
old,and rebooted the system but got the same err msgs again.
 
Any ideas... Help please.
 
Thanks,
 
Huawei Li
