The read only response was after the system came up in maintenance mode.

Absolutely. I didn't start the troubleshooting on the system. It was handed over to me after the first guy had to go home. It was at the maintenance prompt when I got it. They were unable to Ctrl-Brk to the open boot prom since Chris (the H&E guy) couldn't find the ctrl or brk keys. I picked it up there.

The error I had was along the lines of (it's been two weeks) "can't create utmp".

Attempting to umount /var returned the mount point busy message. Chris hit enter on fsck before I could tell him to type in the specific file system I wanted to check. When it got to /var, it responded that /var was mounted read only.

Quote:
btw, what was the last thing that happened to the server prior to it having the boot problem? was it patched and then rebooted? if patched, was the server in single-user mode or without regular user logins/processes at all during the patching?
According to the team lead, an application (a cisco management package) was being upgraded which required a reboot after it was done.

utmpx

utmpx(4)							   File Formats 							  utmpx(4)

NAME

       utmpx, wtmpx - utmpx and wtmpx database entry formats

SYNOPSIS

       #include <utmpx.h>
       /var/adm/utmpx
       /var/adm/wtmpx

DESCRIPTION

       The utmpx and wtmpx files are extended database files that have superseded the obsolete utmp and wtmp database files.

       The  utmpx database contains user access and accounting information for commands such as who(1), write(1), and login(1). The wtmpx database
       contains the history of user access and accounting information for the  utmpx database.

USAGE

       Applications should not access these databases directly, but should use the functions described on the getutxent(3C) manual page to  inter-
       act with the utmpx and wtmpx databases to ensure that they are maintained consistently.

FILES

       /var/adm/utmpx	       user access and adminstration information

       /var/adm/wtmpx	       history of user access and adminstrative information

SEE ALSO

       getutxent(3C), wait(3C)wait.h(3HEAD)
