Yes, it's me again. Running around getting this done! My current problem is I'm trying to image one drive 0 (/dev/dsk/c1t0d0s0) to drive 1 (/dev/dsk/c1t1d0s0). I know that drive1 came out of a Sun Server and it is a Sun drive. Solaris 10 recognized drive1 after the devfsadm command. The commands "dd" and "mount" both react the same.
# mount /dev/dsk/c1t1d0s0 /a
mount: I/O error
mount: Cannot mount /dev/dsk/c1t1d0s0
# dd if=/dev/rdsk/c1t0d0s0 bs=1024 of=/dev/rdsk/c1t1d0s0
dd: /dev/rdsk/c1t1d0s0: open: I/O error
I attempted to prepare a list of answers to possible questions:

c1t0d0s0 isn't a drive but a slice (i.e. partition).
Have you copied the label from the source to the destination drive (prtvtoc/fmthard) ?
Why are you using dd and not ufsdump/ufsrestore if your goal is really to copy a file system as it seems ?
Normally on a Sun drive slice 2 is the whole disk. Did you use the wm subcommand to make the disk writeable and mountable? What is the output from the print subcommand?
First of all, the purpose of using "dd" is to completely image the drive, directly from one to another without the use of single user mode or an interim media.
Thanks to jlliagre, I was able to make it mountable. I'm currently waiting on the dd command to finish up. It's been running for awhile. What time should I expect on an otherwise idle server?
dd stays at about .27% of use. Not too much of a variant.
Sidebar: I plan on using ufsdump/restore in the future when I have an interim media (SAN) to store the fssnap's and when there's a need for incremental backups. I heard there's a way to do it in single-user mode to do it using stdout and two commands seperated with a semicolon. Is it as simple as that?
