RE: [Oscar-users] Problem about install slave nodes with SCSI hard disk?

Hey Kevin:
 
Can you boot up RHEL3's first CD on the node you want to install, go into rescue mode, and show us the output of:
 
lspci
 
lsmod
 
Cheers,
 
Bernard

Dear Bernard Li:
 
Thank you for your response!
I have downloaded the kernel from the URL you afforded and I used this kernel file to replace the original kernel in /tftpboot/kernel.(didn't do any other changes). But it doesn't work as well.
I used DHCP and PXE to install my client node this time.
When I booted up my client node, it can get a IP address from the DHCP server and connected to the master node successfully. It can load the kernel and initrd.img files, but finally it failed to install the client machine.
The output informations from the console are as follows:
 
Start_syslogdget_boel_binaries_tarball

Then it stopped here and prompted a BusyBox V0.60.3 Built-in Shell(ash).
I tried to use lsmod and modprobe aic79xx. And the followed information diplayed.

 insmod: init_module: aic79xx: No such device

I don't know why it can not find the SCSI HDD, since the kernel has included the aic79xx.o module?
I have searched the errors used google.com, but didn't find a solution.
How can I figure it out, which kernel should I choose ?  
Any suggestions are appreciated !
 
Hardware and software information of master and slave nodes:
2*3.6GHz xeon (smp),  1GB ECC RAM,  RedHat EL AS3U3 , Oscar 4.1
Adaptec SCSI control card(driver is aic79xx, vendor: SEAGATE ST336754LW).

Hi Kevin:
 
You can try to use the kernel/boot CD available here, it should have the drivers for your SCSI hardware:

Subject: [Oscar-users] Problem about install slave nodes with SCSI hard disk?

 
Dear members:
 
I have 20 Dell precision 470 Workstations ,each has 2*3.6GHz Xeon CPU, 1GB ECC RAM, 36 GB SCSI HDD (Adaptec SCSI Control Card), PXE supported.
I have installed RedHat Enterprise Linux AS 3.0 Update 3 in one of these computer as the server node.  When I used the boot CD to install RHEL AS3 U3, It can automatic install the SCSI driver(aic79xx).  Now, I have successful configured and installed OSCAR4.1 in the server node.
 
My problem happened when I tried to install the client nodes, as follows:
In step 6: setup networking
Because the dhcpd service in server node cann't start(conflicted with an existed dhcpd server), I used mkautoinstalldiskette -config  FILE  to creat a boot floppy.
When I used the boot floppy to boot up one client node, It can find the server node and excute the /var/lib/systemimager/scripts/(clientname).sh.  But a error message appeared " NO DISK DEVICE FILES WERE FOUND.  THIS USUALLY MEANS THE KERNEL DID NOT RECOGNIZE ANY OF THE ATTACHED DISKS".
 
Then,  I tried to use mkautoinstalldiskette -config FILE -kernel  $Path_to_the_kernel_as_server_node  -initrd  $Path_to_the_initrd_as_server_node to creat a boot floppy and used it to boot up the client node.  But a new error message displayed,"Kernel panic: No init found. Try passing init=option to kernel"
 
So, I am puzzled by these problems. I think the problem focus on how can  the SCSI driver be loaded successful.
Can anyone help me out with these problems?
 
If I used the dhcpd server and PXE to boot the server nodes, can the server nodes load the SCSI driver aic79xx with the default kernel ?
