You say that your device nodes (eg, /dev/dsk/c0t0d0s0) are all missing.
devfsadm=DEVice FileSystem ADMinistration
With the switches that I specified it will recreate the device nodes in all directories (/dev/dsk, /dev/rdsk, /dev/cfg) for the filesystems it can see during its search.
So looking in /dev/dsk and /dev/rdsk you should see the device nodes after running this command. As said, you need to boot from cd and mount your hard disk root filesystem under /a. (The switch "-r /a" tells devfsadm that the root filesystem is there).
After that you should check (carefully) the /etc/vfstab (/a/etc/vfstab) to ensure it tells Solaris where to find all the filesystems (eg, /usr).
Finally you must reboot with "boot -r" and wait for Solaris to reconfigure everything as it boots.
Thank You for all your responses..
I managed to get the server back up and running..
Started throwing up errors.
so I
Then mounted the file system on /a
Worked like a charm.
Thank you once again.
