Changing the SCSI Adapter without re-installing

Hello There,

I had to install an Intranet Application under RedHat Linux 9.0 + Tomcat + Java + MySQL in an HCL Server.

The server configuration is Intel Xeon 2.4 GHz, 1 GB RAM, 36 GB SCSI with built-in Adaptec Ultra320 SCSI adapter.

When I tried to install Redhat Linux 9.0, it was not detecting the SCSI adapter. Since I was not able to find the driver for the built-in SCSI adapter, I disabled the adapter from the BIOS and plugged in an Adaptec Ultra160 card which the OS detected and installation was smooth after that. The server is up and the application is running perfectly. Let me tell you one more thing that the application which I am mentioning requires lot of configurations.

Now my problem is, I found out the proper driver for the on-board Ultra320 SCSI adapter and I want to use it instead of the current Ultra160.

Can somebody tell me what should I do, or how should I load the driver into the Linux server befor plugging out the Ultra160 card and enabling the on-board SCSI card. I dont want the system to crash and re-installed at any cost.

Requesting the experts to gove me a quick solution.

With nest regards

1. Make a backup. For speed in "recovery", you could perhaps use an imaging tool like partimage (http://www.partimage.org) or ghost.

2. Make the kernel aware of the "new" driver.... probably involves building/installing a kernel module for it, editing /etc/modules.conf (to add an "alias scsi_hostadapter <xxxxx>" line), then running mkinitrd, fixing grub config etc.

3. move the drive(s) over.

Hi Glenn,

Thanx for your suggestions.

Could you please eloborate on the step 2. I'm not very good at compiling kernal etc.

Thanx once again.

Hm, could you point out where (and what) info you've found so far? It's probably easier if I try help with specifics than trying to guess what you already know:-).
