need help loading aic79xx.o offline


Hi all,

i am working on an old server with Red Hat AS3 and it had the adaptec 7902 A4 hostraid adapter. i need to remove the hostraid module "aa320raid.o" and put the aic79xx.o module so it will work with the adapter as a simple scsi disk.

the issue is that i cannot use the modprobe to install the driver as the server is offline. i am looking at any way to make the server load the aic789xx.o driver by modifying the config files from live cd "by mounting the disk". i have the module in the /etc/modules.conf but it is not loading it but instead is loading the a320raid.o. commented out the line of the a320raid.o
#alias scsi_hostadapter a320raid
alias scsi_hostadapter aic79xx

changed the scsi_hostadapter1 aic79xx to scsi_hostadapter aic79xx to have the correct numbering

and it still is loading the a320raid.o module.


please someone help me.

thanks to all

The obvious question is, have you called Red Hat support? You're using a commercial, PAY FOR, distribution, and as such, pay for access to their tech support and online knowledgebase.

You can blacklist the current driver:
https://access.redhat.com/site/docum...cklisting.html

...but at that point, how do you expect the system to boot, if you can't access the disk(s) any longer? Boot the server, remove the module(s) you want, load the other modules that you want, and create a new initrd image:
https://access.redhat.com/site/docum...isk_Image.html

thanks for the reply.

i got this server and need to support it. they don't have the red hat support for this. the issue is that the server is now offline and cannot boot on the old controller so what ever i had to do i need to do with it offline via live CD. do you have any link for creating a new offline initrd image for 2.4-15 kernel ?

That's an easy fix...just call Red Hat, and they can register it over the phone.

From your first post, you indicated that it was still loading that module...so how can it load ANY modules if it can't boot? If you need to create an initrd image, follow the link I already sent you. If you're booted from CD/DVD, mount the hard drive manually, or put in a thumb drive or some other device you can write to, and create the image there.
