Joseph GanSystem AdminCommented:
The error message looks to me was the booting process couldn't find the root filesystem on the disk. The link you provide is something to do with re-installing boot block. Try to mount the root filesystem from the DVD, find out the disk controller, target, disk and slice number, ie (c?t?d?s?), compare it in /etc/vfstab file.

The boot disk is c1t0d0s0, its weird but I dont see infos on the vfstab

i did

mount /dev/dsk/c1t0d0s0 /a
and when i type

more /a/etc/vfstab i see no such file or directory


I only see the vfstab of the cd ,  its weird

thanx ganjos. What can I do to fix this issue

Joseph GanSystem AdminCommented:
If you couldn't find files on your disks, only way could do is re-install the OS. Do you know how could this happened before the reboot?

cismoneyAuthor Commented:
I suspect that the application support tried to install a patch, but they do not admit it

Its weird I can't find /etc when I boot the system on a single user mode with the solaris dvd

Joseph GanSystem AdminCommented:
Patching shouldn't cause this kind of problem, unless someone deleted files under /etc directory. Do you have any OS backup around ? The root filesystem could be on other slice, ie, s1, s3 etc ... ?
