........I have a new hard drive and I need to copy ALL info from the old to the new. I would like to use the dd command. I know the command is as follows......

dd if=/dev/rdsk/c1t1d0s0 of=/dev/rdsk/????????

Where I have the question marks is the problem.
How do I find out what the id is?

Thanks in advance.

shorty,

This looks like a solaris box. If its is, its is most likly c1t2d0s0. It will depend on how to formatted the disk. If you are on a sun box. Use format command to look at how it is name. Using format will not change anything IF you just use it to look at the disks. Please do man on format command before using it. I think if you use df -k it should also give you disk naming.

df -k would only show you the device if it was currently mounted. Yes, the format command is probably the way to go. Did you remember to do a boot -r (or touch /reconfigure then init 6) after you added the new disk? If not, run devfsadm. Then the appropriate device entries will be created and you should be able to see the disk when you run format. You can use dd, or even ufsdump|ufsrestore to transfer your data. You're best to umount the source disk before you copy - if anything is writing to the filesystem whilst you're copying it's contents you could end up with corrupt data.

Ok......I did a format and the new drive showed being c1t2d0.
So I did a dd if=/dev/rdsk/c1t1d0s0 of =/dev/rdsk/c1t2d0s0 and the following error showed up........
dd: /dev/rdsk/c1t2d0s0 open: Invalid argument

I did some research and the consensus is that slice 2 would span the entire disk, so I tried dd if=/dev/rdsk/c1t1d0s2 of=/dev/rdsk/c1t2d0s2 and the same error came up.

Any suggestions

Progress...........I had to label the drive......i typed format and it asked me if i wanted it labelled.......then i did dd dd if=/dev/rdsk/c1t1d0s2 of =/dev/rdsk/c1t2d0s2 and it's been running for about an hour and a half. Maybe I should have specified the blocksize?!?!
