Using Clonezilla live with non-conventional device names
A partition and disk imaging/cloning program

I'm trying to use Clonezilla Live (alternate Ubuntu version) to make disk images on an older server with a Mylex ExtremeRAID-2000 SCSI RAID controller and a Promise FasTrak SATA RAID controller.
If I go to a command prompt when booting Clonezilla Live and check out /dev (or use a command like lsblk), I can find the disks attached to both controllers, and then mount and read the partitions on the drives without problem. Thus, the Ubuntu drivers are working.
As far as Clonezilla goes, there are no problems with the drives attached to the Promise controller, because the drives are named conventionally (i.e. /dev/sda, /dev/sdb).
Unfortunately, the Mylex controller uses a non-conventional format: /dev/rd/c0d0, /dev/rd/c0d1, etc. I assume that 'c' is for channel, and 'd' is for disk on that channel. The drives are not directly under /dev, but there is a directory 'rd', and then the drives are found. As such, the Clonezilla user interface does not list the drives attached to the Mylex controller because they don't use conventional naming such as /dev/hda or /dev/sda.
If I were to go to command mode and try to run Clonezilla manually, with a command like
Would it be possilbe to specify the Mylex drives for the DEVICENAME parameter? Normally, you would specify something like 'sda' for DEVICENAME. Could I use 'rd/c0d0', or is this something that ocs-sr cannot handle?
Due to lack of server downtime, I can't really play around, so I would like to have a known working solution going in. I suppose 'dd' would be an option.
Thanks!
These device names /dev/rd/c0d0, /dev/rd/c0d1, are not supported. It has to be improved by modifying /usr/share/drbl/sbin/ocs-functions.
Here I do not have such a device so it's not easy for me to modify that.
If you modify ocs-functions and it works for your device name, please send me a patch file.
Thanks.

Oh, this device name (/dev/rd/c0d0) is very similar to /dev/cciss/c0d0. I could modify that, and it should be ready in the next testing release.

Please give Clonezilla live 2.3.1-9 or 20141104-* a try:
http://clonezilla.org/downloads.php
The format like /dev/rd/c0d0 is not supported.
Please let us know the results.
Thanks.
