Duplicating a drive

[Mark Grant]

No, I didn't mean that, sorry. Your "dd" using the disk devices probably won't work because the disks are different sizes.

I meant, create logical volumes on the second disk that are the same size as the volumes on the first disk and then use "dd" on each logical volume using the device "/dev/vgXX/lvolX". as in "dd if=/dev/vg00/lvol2 of=/dev/vgbackup/lvol2 bs=4096"

I'm not saying this will work but it might. However, the Ignite option taht everybody keeps talking about is still a good option :)

John,

Go the Ignite route!!!!!! Your tape drive will handle it just fine!!!!

Ignite is much easier. If you crash your machine, you just put the tape in, boot from and let your machine rebuild.

I hir ctrl-C and it said 122881+0 records in
122880+0 records out.
Was it doing it?

[Mark Grant]

It was copying records from one disk to the other. It didn't finish though :)

Please consider Ignite. You will have fun trying to get other solutions to work but Ignite is much more fun when re-building in an emergency.

When I tried my used tape drive with new tapes I got an I/O error. That is why I was going to try the 9gig hard drive.

[Mark Grant]

Is it possible you were putting DDS3 or 4 tapes in a DDS 2 drive?

[John Ramsay_2]

I added the tape drive and tried to reboot and like I thought the system is toast.
I get:
Exec failed: Exec format error.
then it goes to ISL
Do I have to reload again???

[Mark Grant]

Quite possibly :(

[John Ramsay_2]

Can't I do a make boot or something? What about ISL things?

[Patrick Wallek]

What is the SCSI ID of the tape drive? It is possible that you have a SCSI ID conflict and between theh tape drive and you boot drive.

If this is an external drive, look on the back. There should be some switches or something that let you set the SCSI ID. Make sure it is not set to 5 or 6. Set it 1 or 2 and try booting your system again.
