boot hangs after recovering corrupted kernel

Hi Gurus;

After a patch installation, Solaris 10 kernel has been corrupted. I
used following procedure to recover it:

(from an identical server):


(1) Booted from network
(2) # installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk
/dev/rdsk/c0t0d0s0

(0) On Good server: # cd / ; tar -cvf /tmp/kernel_dirs.tar ./kernel
./platform ./usr/platform

(1) mounted the root FS slice: # mount /dev/dsk/c1t0d0s0 /a

(2) I renamed these kernel directories:
# cd /a ; mv kernel kernel.BAD ; mv platform platform.BAD; mv
./usr/platform ./usr/platform.BAD

(3) ftp'ed them from good server and untarred to original locations:

# ftp goodsvr's ip, lcd /a, cd tmp, hash/bin, mget kernel_dirs.tar
# cd /a ; tar -xvf kernel_dirs.tar
(4) unmounted the root FS slice: umount /a
(5) reboot


After this I received some /kernel .... stale messages, then I booted
in failsafe mode (boot -F failsafe) and updated boot archive. I also
fsck root filesystem and fixed corrupted superblock. Fsck one more
time to make sure any error remained. No error found. After that,  I
tried to reboot. I receive no error message but booting process is
hang at some specific point. To see what is happening I tried to boot
server with boot -rv. Here is the output: (where boot hangs):

Then it is stuck at this point.


Do you have any suggestions? Any answer will be highly appreciated.
