Re: clone hdd
1. bttape
You can backup (and restore with btextract)your system using this utility (see man bttape)
2. # dd if=/dev/rdisk/dsk0c of=/dev/tape/tape0
3. Do "vdump" backup of all file systems to tape. They can be restored wherever you want.
Do consider bttape.
I ussually do backups using "vdump", but bttape image is simple to restore.

Re: clone hdd
If you use bttape you boot from tape device:
>>> boot -fl "nc" MKA600 (or whatever is your tape device).
As I said take a look at man pages for bttape.

Re: clone hdd
How will you do backups without the tape?
From where will you restore the data?

Re: clone hdd
Yes. Create a disk on fibre storage and create file system. It can even be UFS, does not have to be advfs. You would have less problems mounting UFS disk when booted from CD.
Mount that file system somewhere, for example on /bacdisk.
Then do:
# vdump -0f /bacdisk/root.vdump /
# vdump -0f /bacdisk/usr.vdump /usr
etc...
You vdump all file systems which are located on local disk.
You can also try:
# dd if=/dev/rdisk/dsk0c of=/bacdisk/dsk0.dd
if you prefer dd.
When you need to restore you boot from CD.
Then you create partitions on new disk and file systems.
Do not forget to create advfs boot block when doing disklabel.
Then mount /bacdisk and restore from vdump files or from dd file.
