Upgrade Adaptec SCSI Card

Hi,

We have a customer who has a hotswappable back plane supported by an Adaptec
2010s Raid Controller.

They wish to add additional disks but it doesn't seem to be possible with
that controller.  It is a Zero Channel card so when I plug in an extra disk
the existing mirror is immediately unbootable.

We have sourced a 2310 which will do the job but of course Windows 2003
won't boot from it.

I have imported the array from the 2010 and it starts to boot from the 2310
but fails and reboots.  I assume this is because there isn't a driver
installed on Windows 2003 that will support it.

Has anyone ever tried to upgrade adaptec raid controllers before?  If so,
how did you achieve it.  Or is a rebuild or a restore from backup the only way.

Thanks,
Joe

Just a suggestion....

Why dont you have both controller cards connected and boot from the original array on the original controller.  Install the drivers for the new card while the machine is running and make sure Windows is happy with it.

Then shutdown the machine and import the array on to the new controller and at the same time remove the original.

Spent a little more time on this and now see that the server was originally configured with the drives on the highest IDs on the scsi backup plane.  Any additional drives pickup lower IDs and the card attempts to boot from these.

I'm going to have to break the mirror, move the drives down the backplane and recreate the mirror.

A little worried about deleting the array as the adaptec storage manager tells me that deleting the array will delete all data.  I'm sure it won't but any advise would be helpful.
