SUMMARY:- CLONING A BOOT DISK ON E450.

Hi,
   Overwhelmed by all that response. this is one thriving and buzzing
community. Many thanks for all those responses. Special thanks to Richard W.
Rominger for sharing that excellent script to clone boot disk. i am sharing
it with all with his permission.

My Original Q was:-

Hi Gurus,
             i will have to clone my boot (having the /, /var, /usr,
/export/home and /opt filesystems) disk on E450 on Solaris 9. i am wondering
will the following steps work:-

1) prvtoc /dev/rdsk/c0t0d0s2 | fmthard -s - /dev/rdsk/c0t1d0s2
2) use newfs to create the filesystems on the c0t1d0
3) ufsdump 0uf /dev/rdsk/c0t1d0s2 /dev/rdsk/c0t0d0s2
4) use install boot to create the bootblocks.

please help me with this. Thanks in Advance. i will summarize.

thanks
Prabir.


the Solution:-

1) prvtoc /dev/rdsk/c0t0d0s2 | fmthard -s - /dev/rdsk/c0t1d0s2
2) use newfs to create the filesystems on c0t1d0.
3) use installboot to install bootblocks on the new disk (c0t1d0).
3) create a temporary mount point, say, /clone,
4) mount the new slice (say c0t1d0s0) at /clone.
5) use*   * ufsdump 0f - / | (cd /clone; ufsrestore rf -)
6) unmount /clone.
7) repeat  steps  4, 5, 6  for the  rest of the slices of the new disk.
8)  modify the /etc/vfstab  in the new disk to use its slices.


Thanks
