When system was trying to open coreadm.conf, it is needed a tmp space to open the file so it will need /tmp partition to be rw.<br />
fsck /tmp partition, if it not mounted than mount it.<br />
and then try to remount /tmp partition to r/w. <br />
<br />
if these does not work post us these output when system is at single user mode.<br />
format<br />
mount<br />
<br />

The only time I've ever had the<br />
&quot;&nbsp;INIT: Cannot create /var/adm/utmpx&quot;<br />
&nbsp;message is when my /var partition wouldn't mount. <br />
<br />
btw: How many disks do you have and are they mirrored?<br />

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
