Hello, I have a Dell Poweredge 2550 server.  It has 2 RAID containers.  One is a RAID-5, the other is RAID-1.
I need to ghost from the RAID-5 container to the RAID-1 container.  I am using a version of Ghost that requries me to boot into dos from either a diskette or CD.
What do I need to put in the Autoexec.bat and config.sys files so that I can "see" these containers?
Yes the RAID-1 container has more than enough room for the RAID-5 container copy.
I just don't know how to config the startup files(config.sys and autoexec.bat) to see the RAID continers.
Any help out there?
Thanks

Hello mrbodjagles:

You need to install an ASPI driver to run the array in DOS.  I'm not sure which controller that machine uses - there are LSI Logic and Adaptec variants used in Dell servers.  The ASPI layer drivers are pretty well standardized and, depending on the controller features, can be gotten from a number of different sources.

I would build a set of DOS boot disks (or use UBCD, below) with ASPI drivers on them - you can get the drivers from Adaptec, LSI or, perhaps, Dell (see http://support.dell.com/support/downloads/driverslist.aspx?os=DOS&osl=EN&catid=-1&impid=-1&servicetag=&SystemID=PWE_PNT_P3C_2550&hidos=WNET&hidlang=en).

Another option would be to try the Ultimate Boot CD, which can be downloaded from: http://www.ultimatebootcd.com/

warren, I am having a difficult time with this process.
1.  Would the aspi drivers be in both the autoexec.bat and config.sys files?
2.  Which drivers would I use?  Are they generic for a SCSI device?
3.  I have yet to find a dos or windows SCSI Raid driver.
4.  If I do find it how do I assign drive letters to each RAID container?

Thanks again.

I'm guessin you need this:

http://support.dell.com/support/downloads/download.aspx?c=us&l=en&s=gen&releaseid=R55773&SystemID=PWE_PNT_P3C_2550&servicetag=&os=DOS&osl=en&deviceid=1369&devlib=0&typecnt=0&vercnt=3&catid=35&impid=-1&formatcnt=1&libid=35&fileid=66392

Check the list of controllers it supports and make sure yours is in the list.

The instructions on the page are as follows:
--------------------------------
Default Instructions for PERC3-DOS-DC535.exe:

This program creates a diskette that contains a Dos management
application for the PERC 3, CERC and PERC 4 RAID controllers. You will
need a formatted 3 1/2 inch floppy diskette for the following procedure.

1) Download the file to a directory on your hard drive. The
file downloaded is a self extracting executable.
2) Install the formatted floppy diskette into the floppy drive.
3) Double click on the file, .exe, on your hard drive to run the
executable and to extract files to the floppy.
4) To execute this application, boot your server to Dos and then install
the floppy that contains the application into the floppy drive.
5) Type dellconf at the command prompt.
-----------------------------------------
To answer your questions:

1. As far as I can tell you don't need to put anything into the Autoexec.bat or config.sys files - it appears to be a stand-alone application that gives you access to the RAID arrays - beyond that, I can't say as I can't use them.

2. The drivers should be those specific to your controllers (see above - make sure yours are on the list).

3. The link I sent you in my original post has a drop-down list that allows you to select SCSI Raid drivers and the link above is the place that that drop-down list points to.  These drivers are for DOS; if you go back to the original link

http://support.dell.com/support/downloads/driverslist.aspx?os=DOS&osl=EN&catid=35&impid=-1&servicetag=&SystemID=PWE_PNT_P3C_2550&hidos=DOS&hidlang=EN

 and click on the first drop-down menu, you will be able to select drivers for the various flavors of Windows - for example, this link is for SCSI Raid drivers for Windows XP:

http://support.dell.com/support/downloads/driverslist.aspx?os=WW1&osl=EN&catid=35&impid=-1&servicetag=&SystemID=PWE_PNT_P3C_2550&hidos=DOS&hidlang=en

4. Usually drive letters are assigned by the drivers sequentially starting with the first available letter - C:, D:, etc. although some drivers allow you to set the assignment sequence; I can't say what the Dell drivers will do - I cannot unpack them on any of my machines (they appear to be Dell-specific).
You only need a DOS driver if you plan to use the DOS version of Ghost.

I <think> the process is as follows:

Boot into Dos from a diskette.
Run the Dell driver diskette (see the first link in this post).
Run Ghost from diskette or CD
